series of suppurating compound fractures, but during my whole experience
I have never seen so many cases of what might be regarded as fairly pure
instances of acute osteo-myelitis. The symptoms corresponded with the
main seat of the suppuration; only moderate swelling of the limbs
occurred, this mainly consisting in soft superficial oedema; often
there was no redness, and fluctuation was difficult to determine. At the
same time symptoms of constitutional infection, such as continued fever,
rapid pulse, restlessness, loss of strength, progressive anæmia, and
emaciation, were marked. Pyæmia, as evidenced by secondary deposits,
was, however, rare; I only saw two cases, both in fractures of the
femur; in both recovery followed secondary amputation.
_Prognosis._--This depended almost entirely on the nature of the injury
to the soft parts; given moderate injury to these, and the preservation
of the wound from infection, scarcely any degree of injury of the bones
precluded recovery, even if this were slow and prolonged. The existence
of perforations scarcely increased to an important extent the gravity of
a wound of the soft parts alone; in fact, this injury could not be
regarded as more severe than an ordinary surgical osteotomy, putting the
risks of infection of the wound under the special circumstances on one
side.
With regard to the functional results, these depended on the degree of
comminution; when this was extreme, union was slow and for a time weak,
and shortening was often considerable, but a fair result was as a rule
obtained.
Suppuration and osteo-myelitis were the dangerous features when they
occurred; still, even in the presence of these, I never saw a fatal
result in an upper extremity fracture, although in the lower extremity
a considerable mortality followed fractures both of the leg and thigh,
the deaths being most commonly from septicæmia, or from a combination of
this with secondary hæmorrhage.
_Treatment._--The general treatment was of a simple character. The
perforations may be at once dismissed, since nothing more was needed
than what has been already described under the heading of wounds of the
soft parts. Again, with regard to the co-existence of vascular injury,
or injury to the soft parts generally, the ordinary rules guiding us in
civil practice were followed.
The first point of importance, and needing consideration in the
treatment of severely comminuted fractures, was as to whether in these
it was better simply to try to obtain union of the wound with as little
disturbance as possible, or to anæsthetise the patient and explore the
wound, removing such fragments as were free or widely displaced. I think
the answer to this question depends entirely on the nature of the
external wounds. If these be of the small type forms, or if the exit
aperture is, at any rate, of only moderate size, a strictly conservative
attitude is the better when the risk of making an exploration under the
circumstances is borne in mind, the more so as an exploration, to be
safe and useful, ought to be done at once. If the exit wound is of the
large or explosive type, on the other hand, there is no doubt that the
best results are to be obtained by early exploration and the removal of
all loose fragments. I saw several excellent results obtained in this
way, even when the patients had to undergo the risk of transport
shortly, in some cases the very next day, after the operation. The loose
fragments are an immediate source of danger, and later may interfere
with the healing of the fracture, even if suppuration does not occur. In
all the cases that I saw the exit wound was dressed, but left freely
open, and I do not think any attempt to close it should ever be made.
The question of operative fixation rarely needs consideration; it
occasionally happens, however, that oblique fractures, such as one
mentioned on p. 166, are met with, in which screwing or wiring of the
bone ends is advisable. What has been said above as to fractures,
accompanied by loss of continuity, applies equally to cases of severe
wedge-fracture, where many loose fragments exist.
As to the disinfection of the limb, primary cleansing, mainly by soap
and water, of course precedes the exploration, and when the latter has
been carried out a second cleansing and disinfection, preferably with
spirit and carbolic acid lotion, are imperative.
Immobilisation is a more difficult problem. In practised hands
plaster-of-Paris splints answer most requirements except in the case of
the thigh; but the splints take time to apply and also to set firmly,
and, as sometimes needing frequent removal, are not altogether suitable
for Field hospital work. Of all the splints I saw in use, I think the
best were wire splints, and the Dutch cane folding splints for the thigh
and leg (figs. 56, 58); wire-gauze splints with steel at the margins
(fig. 54), or strips of ordinary cardboard applied with some variety of
adhesive bandage for the arm and forearm; and plain wooden of various
lengths for any situation.
A question of constant difficulty was that of frequency of dressing; in
a Stationary or Base hospital this is not difficult, as the same surgeon
has the patient continuously under his charge, and can readily decide as
to the proper moment for the renewal of the dressing. When the patient
is, however, being moved from the Field to the Stationary hospital, and
thence to the Base, a constant succession of surgeons has the case in
hand for short periods, the movements during transport disturb the
fixity of the dressing, and, in consequence, dressings are apt to be far
more frequent than is advisable. This question raises the larger one of
the advisability of _any_ transport beyond what may be an actual
necessity. There is only one answer to this. No fractures of the thigh
or leg, and few of the arm, can be transported for any distance without
material disadvantage. The risks attendant on disturbance of the
fracture and tissue injury, septic infection as a result of slipping of
the dressing and the impracticability of efficiently renewing it, far
more than counterbalance any advantage to be gained from the superior
comforts available at a Base hospital. For these reasons, if possible,
all fractures of the arm, thigh, or leg should be kept at a Stationary
hospital for a period of three or more weeks, and, as far as splints and
appliances are concerned, these should be as numerous and complete as at
a Base hospital. I have had a useful set made of aluminium. A word will
be added later as to the splints suitable for different regions of the
body.
The necessity for _primary amputation_ chiefly depends on the nature of
the injury to the soft parts, less commonly on the extent of the injury
to the bones, and should be decided on exactly the same lines as in
civil practice. So-called intermediate amputations are always to be
avoided if possible; the results were consistently bad, and the
operation should only be undertaken in cases of severe sepsis where
little can be hoped from it, or for secondary hæmorrhage. When the
operation could be tided over until the septic process had settled down
and localised itself, secondary amputation gave very fair results. In
either intermediate or secondary amputation for suppurating fractures,
it was necessary to bear in mind the special likelihood of the existence
of extensive osteo-myelitis. If this condition affected the upper
fragment, an amputation was of little use unless the whole bone was
removed, as septic infection continued and brought about a fatal issue,
or a fresh amputation was required in order to obtain a stump that would
heal.
SPECIAL FRACTURES
_Upper Extremity._--Fractures of the _scapula_ were not uncommon, but
were mostly of the perforative variety; thus perforations both of the
spine in longitudinal wounds of the back, and of the ala in perforating
wounds of the thorax, were tolerably frequent. They possessed little
practical interest; as a rule, the openings were not large, and the most
unexpected feature was the small interference with the movements of the
bone on the chest wall that resulted. It might be assumed that
comminuted fragments would project into the muscles and cause both pain
and interference with movement; but neither was the case. I saw grooving
of the crest of the spine, but never happened to meet with a fracture
of the acromion process. Many axillary tracks passed in the closest
proximity to the coracoid, but this again I never saw separated. One
practical point of importance with regard to the scapula was the
frequency with which bullets lodged in the venter, or the firmly
bound-down muscles of the supra- and infra-spinous fossæ. These retained
bullets often gave rise to remarkably little trouble in this situation;
thus I have a skiagram of a shrapnel bullet lying in the deepest part of
the subscapular fossa, which did not inconvenience its possessor.
[Illustration: FIG. 53. Head of Humerus, showing broken perforation. The
roof forms a hinged covering to a groove.]
Every variety of _fracture of the clavicle_ was met with, even
perforation of the most compact portion of the shaft; comminuted, wedge,
or notched fractures were, however, the more common, and were
accompanied by the development of very large masses of provisional
callus during the process of healing. An interesting skiagram is
reproduced in plate III., which shows a compound form of injury to the
clavicle. The bullet has passed obliquely beneath the acromial end,
rising to perforate the posterior compact margin, and producing one of
the diamond-shaped openings sometimes occurring in compact bone with the
passage of bullets at a low rate of velocity. No case of perforation of
the subclavian vein by comminuted fragments of the clavicle came under
my notice.
_Fractures of the humerus_ of every variety were common, and I think
when the statistics of the campaign are published, it will be shown that
the humerus was the most frequently injured individual bone in the whole
body. I remember to have seen thirteen fractures of the shaft of the
humerus in one pavilion alone at Wynberg after the battle of Paardeberg.
Perforations of the upper articular extremity were common, and as a rule
gave rise to wonderfully little trouble in the shoulder-joint. The outer
aspect of the head of the humerus is a common situation for the
production of a special form of broken canal or groove (fig. 53). The
slope from the greater tuberosity to the shaft naturally favours the
production of the injury in this position.
I saw only one case in which a vertical fissure extended from a fracture
of the shaft into the shoulder-joint; in this case the transverse
solution of continuity was at the upper part of the middle third of the
bone. Skiagram, plate IV., illustrates a well-marked stellate
comminution of the shaft with large fragments. Plate V. shows extreme
comminution with fragments blown out of the wound. Two plates, Nos. VI.
and VIII., illustrate well the difference resulting from the oblique
passage of a bullet at high and low rates of velocity respectively. In
both cases good results were obtained; in the more severe the resultant
mass of ensheathing callus was very large, temporarily interfered with
flexion of the elbow-joint, and consolidation was very slow (see plate
VII.). The patient was wounded at Belmont in November 1899, but he was
able to row at the end of the summer of 1900, although very prolonged
suppuration occurred, and the elbow movements became practically normal.
Plate IX. illustrates a transverse track, the bullet having undergone
considerable injury during its passage through the bone, as evidenced by
the presence of fragments both of mantle and lead in the limb. This
might be called an example of transverse fracture, and illustrates the
nearest approach to one seen when the bone is struck fairly plumb.

The wound track took a directly antero-posterior course. Impact
rectangular. The musculo-spiral nerve was completely divided.
The plate affords a good example of the so-called 'butterfly' fracture.
Two long doubly wedge-shaped lateral fragments, and pointed extremities
to both main fragments, are shown.
The fracture healed well, with the deposition of a large mass of
provisional callus. The musculo-spiral nerve was united by suture some
three months later.]
Plate VIII. exhibits an oblique fracture of the lower part of the shaft
produced by a bullet passing at a low rate of velocity. It does not
widely differ from a perforation, and the illustration possesses some
further interest as showing the deviation of a bullet likely to occur
when a bone lies in its course. Although the velocity with which this
bullet was travelling must have been very low, when the bone had been
traversed the deviation in its course was slight. A few bony fragments
from the compact tissue of the posterior surface of the humerus have
been carried into the distal portion of the track.
Fractures of the various prominences of the lower articular extremity
were not uncommon, but deviated little from the types with which we are
familiar in civil practice; the after results were good, both as to
union and movement of the elbow.
Explosive wounds of the soft parts were not infrequent in the arm, and
fig. 48, p. 158, exhibits an extreme example. The humerus in respect of
depth of covering, however, comes between the femur and the bones of the
leg and forearm; hence such injuries were not so easily produced as in
the latter segments of the limbs.
In connection with the subject of fractures of this bone, one word must
be added as to the occurrence of the most characteristic of its
complications, musculo-spiral paralysis. This was frequent in every
position of the fracture, and came on either immediately, or, at a
subsequent period, as a result of callus irritation or pressure. Its
frequency is only what would be expected when the nature of the fracture
is considered, but the chief interest of the condition lay in the
difficulty of certainly detecting it in the initial stages of the cases;
this depended on the fact that in many of them the local shock to the
limb was so severe that the function of the whole of the muscles was
lowered, or in some cases, although the musculo-spiral was the nerve
chiefly affected, the other large trunks had also suffered concussion or
contusion. In consequence of this difficulty the actual localised
paralysis often only became evident at the end of a week, or even more,
when there was difficulty in deciding as to whether the paralysis was
primary or due to secondary trouble. In the fracture illustrated by
skiagram, plate IV., the nerve suffered complete division, and was
united some three months later, improvement in the symptoms being very
slow. The latter was a common experience, and although not unusual in
civil practice, I think it is more marked in these injuries as a result
of the more widespread character of the nerve lesion.

(25) COMMINUTED FRACTURE OF THE HUMERUS
Range '50 yards.' Velocity extreme.
Impact somewhat oblique. The bullet entered anteriorly about 3 inches
above the elbow crease. The wound of exit was on the inner aspect of the
arm and explosive in character; it still measured 4 inches by 2 inches
three weeks after the injury was received.
The wounds suppurated locally, but at the end of six weeks fair union of
the bone had taken place and the wound of exit had contracted to a
sinus. The musculo-spiral nerve was concussed, but not divided.
The skiagram was taken three weeks after the reception of the injury.
Comparison with plate IV. demonstrates the effect of high velocity in
free comminution of the bone, the sharper radiation of the stellate
lines of fracture, and the propulsion of bone fragments.]
The _bones of the forearm_ were also often fractured. The principal
peculiarity of these fractures was the common localisation of the injury
to one bone, which is readily seen to be probable.
Each bone offered some special features dependent on its structural
character and anatomical position. In the case of the _ulna_, pure
perforation of the olecranon process, without obvious evidence of
implication of the elbow, was seen on several occasions. The other
important feature with regard to this bone depends on its subcutaneous
position, which accounted for the frequency with which highly developed
explosive exit wounds were met with. One is figured in the general
section (fig. 47, p. 156). This, however, is a very slight instance
compared with what was often seen in the upper and middle thirds of the
bone, where the lateral soft parts often protruded as a much larger
tumour, the particular illustration being mainly designed to show the
nature of the injury to the skin. The _radius_, as more deeply placed in
the upper part of its course, was less often the seat of such
well-marked explosive injuries; but when the lower end was struck this
character was sometimes very striking: thus in a track passing
antero-posteriorly through this bone, the whole lower end appeared
shattered, all the tendons at the back of the wrist being implicated in
the protruding mass, while the bone itself seemed shortened, so that the
hand took up the position common in Colles's fracture. It was found
impossible to place the bone in good position; nevertheless the patient
retained his hand, which is still of use in writing.
Plate X. is a good example of a high-velocity injury in which lateral
contact with the radius has produced local comminution, some slight
injury to the casing of the bullet, and the separation of a large wedge.
The case from which this was taken also illustrated well one of the
chief troubles of such fractures of the forearm; the degree of
splintering resulted in the formation of a large mass of callus, which
for a time rendered any degree of pronation and supination impossible.
[Illustration: PLATE VI.

(26) COMMINUTED FRACTURE OF THE HUMERUS
Range '250 yards.'
Impact oblique. Wound of entry 1 inch below the insertion of the
deltoid; exit, on inner aspect of arm at a slightly lower level. The
bullet probably struck the bone laterally, and drove out the central
fragment.
Prolonged suppuration resulted, but the humerus healed well, and good
movement of the elbow was preserved.
The effect of oblique impact together with high velocity is well
illustrated. Had the resistance been greater, as in the case of the
femur, a nearer resemblance to the effect seen in plate XV. would have
been the result.]
Of _fractures of the hand_ I have little to say. In the case of the
_carpus_, the slight degree of resistance offered by the bones rendered
injuries of an explosive character rare. I never saw one. Fractures of
the _metacarpus_, on the other hand, presented exactly the opposite
features. The density of these small bones was well illustrated by the
frequency with which the bullet suffered injury, even amounting to
fragmentation, and the great comminution they themselves suffered. The
breaking up of the bullet in these fractures was a curious feature,
which may perhaps be explained by the tendency of the distal part of the
limb to be driven in the course of the bullet, with the result of
somewhat lengthening the period of contact of the projectile, or more
probably by somewhat frequently occurring irregular impact. Plate XI. is
a good example of an injury of this nature of moderate severity. The
soft parts suffered much in these injuries, the tendons were torn and
lacerated at the moment, and were very apt to acquire more or less
permanent adhesion. This latter condition was sometimes to be improved
by the removal of bone fragments, and I have freed tendons from actual
clefts in the bones where they had been carried in by the bullet. In
some cases very great deformity of the digits, due to shortening,
developed, even when no fragments were removed beyond those blown away
by the bullet.
One form of injury of some interest was multiple fracture of the
phalanges produced by a bullet travelling in a course parallel to the
length of the rifle when pointed by the patient. Occasionally several
digits were lost.
_Treatment of fractures of the upper extremity._--The general lines of
this have already been foreshadowed in the general section, the remarks
as to transport being applicable to all serious fractures of the shaft
of the humerus, and this is the only one of the bones of the upper
extremity on which anything special need be said, as the treatment of
all the other fractures exactly coincides with that of ordinary civil
practice.
[Illustration: PLATE VII.

(26_a_) CONDITION OF THE SAME FRACTURE SHOWN IN PLATE VI., A YEAR AFTER
ITS PRODUCTION
The ensheathing callus is still very abundant, but less so than at an
earlier date. No trouble with the musculo-spiral nerve was noted, but
residual abscesses occurred from time to time in connection with the
fracture.]
[Illustration: FIG. 54.--German Wire Gauze Splint on steel wire
foundation.
(German Ambulance, Heilbron)]
The treatment of wounds should be on the lines already laid down:
thorough cleansing, and then an attempt to seal. In severely comminuted
fractures, however, the exit wound may be of very large size, and then
frequent dressings are necessary. Loose fragments, by which those freed
from their periosteal connections are meant, need removal. The question
which most interested me was the best method of fixation. This needs to
be sufficient to effect immobility, but on the other hand in many cases
the weight of the arm as a means of extension is very valuable. Some of
the most successfully treated cases that I saw were fixed by means of
simple strips of pasteboard, applied moist, and fixed with an adhesive
bandage. Ordinary book-muslin bandages are as good as anything for this
purpose, as they can be reinforced by a stronger form outside them.
Where necessary, an angular piece of cardboard can be applied on the
inner aspect, or a wooden angular splint may be substituted, if it is at
hand; but in this case most of the advantage of the weight of the arm as
a means of extension is lost. The cardboard cases possess the great
advantage of being readily cut off and reapplied much as is done with
plaster of Paris. During the period in which dressing may be necessary I
believe this form of splint is as good as can be got for use in Field
hospitals, the only point needing care being to ensure that the
bandaging is not too tight. It is much more reliable than are ordinary
splints if transport is unavoidable, and is much lighter and less
irksome to the patient. With such strips of cardboard, a few of the
gauze splints (fig. 54), and a few angular and wooden splints, I believe
a Field hospital is fully equipped for the treatment of any fractures of
the upper extremity.

(27) OBLIQUE FRACTURE OF THE HUMERUS OF THE NATURE OF A PERFORATION
Range more than '1,000 yards.'
The distance was probably much greater, as the bullet was retained and
undeformed, and the comminution of the bone was very slight. The wound
of entry was just below the elbow.
The bullet has cut its way through the inner half of the humerus,
producing little comminution and mere solution of continuity of the bone
without displacement]
_Fractures of the pelvis._--These, as a rule, were of so slight a nature
as to form a very insignificant part of the entire injury with which
they were associated, or when uncomplicated they were of little more
importance than simple wounds of the soft parts. The very great majority
were of the simple perforating type. I had the opportunity of examining
three at the brim of the pelvis, these all passing in a downward
direction. The openings were of about the same calibre as the bullet,
and at their entrance was a small amount of bone dust such as would be
found at the entry hole of a gimlet. It was these that made me consider
the possibility of the rifle grooves having some part in the ease with
which certain perforations are made. Of a large number of cases in which
bullets traversed the ilium, the openings in the bone, as a rule, were
with difficulty palpated. I must say that I was astonished that I never
met with an instance of an extensive stellate fracture in the case of
the ilium. Such may have occurred in some of the cases fatal on the
field or shortly afterwards, but I never came across one in the
hospital. It says much for the combined density and toughness of the
human pelvis.
Comminuted fractures were, however, occasionally met with when the
bullet passed in a track parallel to the plane of the bone. One such of
an unusual character has already been mentioned on p. 171. A still more
interesting form, and one highly characteristic of flat bone injuries,
is shown in fig. 55. The patient, a man wounded at Modder River, was
struck at a range of 300 to 400 yards. The bullet entered over about the
centre of the ilium and emerged in the anterior abdominal wall about 2
inches above the anterior-superior spine. As there was some doubt as to
penetration of the abdomen, and as the exit wound was of considerable
size, the wound was explored, an anæsthetic having been given. A
clean-cut track in the bone was discovered which allowed the middle
finger to be placed in it. There was little splintering of either inner
or outer table of the bone beyond the width of the track, but plates of
each table adhered on the one side to the origin of the gluteus medius,
and on the other to the iliacus, the latter muscle being somewhat widely
separated from the venter ilii by effused blood. There was no
perforation of the abdominal cavity.
[Illustration: PLATE IX.

(28) LOCALISED COMMINUTED FRACTURE OF THE HUMERUS
Range '100 yards.'
The entry and exit wounds were on the front and back aspects of the arm,
about 3 inches above the elbow.
Fragmentation of the mantle of the bullet has occurred. It will be noted
that the fragments are lodged in both the proximal and distal segments
of the track. This may indicate that the bullet was damaged prior to
entry, or the recoil of fragments. I incline to the latter view. The
skiagram was taken a fortnight after the injury.
The large median fragment carried forwards, and the small degree of
comminution, suggest the decrease of resistance and prolongation of
impact by carriage back of the arm when struck.
The fracture is one of the nearest approaches to a transverse cleft that
I met with.
The plate may well be compared with No. XII., where the effect of
increased resistance in augmenting the degree of comminution is seen.]
Lesser degrees of the same kind of injury amounting to grooving of the
surface or notching of the crest of the ilium were not uncommon, and the
occasional large character of exit openings in buttock wounds pointed to
contact of travelling bullets with other parts of the external pelvic
wall.
[Illustration: FIG. 55.--Clean Gutter Fracture of the Ilium (range
placed by patient at 300 yards. Highland Brigade, Magersfontein). The
gutter was clean cut, and admitted the forefinger. The inner and outer
tables of the bone were in part blown out of a large irregularly
circular exit opening about 1-1/2 in. above the crest of the ilium. The
cancellous tissue was probably entirely blown out. Plates of the outer
and inner tables still remained connected by their periosteum to the
deep aspects of the iliacus and gluteus medius muscles. The peritoneal
cavity was not opened. The patient did well. Compare with the gutter
fractures of the skull shown in figs. 64, 66.]
Certain portions of the pelvis were subject to more severe comminution;
thus in one case in which the bladder was wounded, a very much
comminuted fracture of the horizontal ramus of the pubes was produced by
a bullet which subsequently lodged in the thigh behind the femoral
vessels. In this case the track was so oblique as to have necessitated
almost pure lateral impact on the part of the bullet; hence the form of
injury was nearly allied to the comminutions of the ilium already
described.
[Illustration: PLATE X.

(29) Wedge-shaped Fracture of the Radius
Range 'a few yards.'
The officer shot the man, his assailant, with a revolver. The entry
wound was on the posterior aspect of the forearm at the junction of the
middle and lower thirds. The exit wound was on the anterior aspect of
the forearm, 1 inch below the elbow crease, and of moderate size.
Some fine fragmentation of the mantle of the bullet is indicated, and
very fine comminution of the bone. The fracture healed well, but the
resulting mass of callus at the end of three months prevented any
movements of pronation or supination.]
I never observed a fracture of the floor of the acetabulum by a bullet
which had entered from the back of the pelvis, although tracks entering
by the great sciatic notch were not infrequent. I saw one case in which
a bullet which traversed the upper part of the shoulder and emerged at
the axilla entered a second time an inch behind and above the anterior
superior spine, and split off a layer of the outer table of the ilium of
the extent of two square inches, which involved the upper portion of the
rim of the acetabulum. No displacement upwards of the femur resulted;
but external rotation was accompanied by crepitus. The wound suppurated,
and some general infection resulted, but six weeks later there was no
evidence of fluid in the hip-joint, the limb was adducted and slightly
rotated outwards, and some movement in each direction could be made
without causing any great amount of pain. I can say nothing of the
further course of this case, as I neglected to take the patient's name.
I saw one or two instances of perforation of the sacrum. One is
mentioned in the chapter on injuries to the abdomen, in which a central
puncture at the level of the fourth vertebra was accompanied by
temporary incontinence of fæces.
Fractures of the _femur_ were fairly numerous and formed one of the most
serious classes of case we had to treat, as well as one of the most
fertile sources of mortality in the Base hospitals. In spite of the last
observation, however, it is probable that the results in this campaign
will be far better than in any previous war, both as to the smaller
proportion in which amputation was needed and as to recovery.
[Illustration: PLATE XI.

(30) COMMINUTED FRACTURE OF THE SECOND METACARPAL BONE
Large fragments of the mantle of the bullet.
Fragmentation of the bullet was comparatively common when the metacarpal
bones were struck, also free comminution of a somewhat coarser variety
than that seen when bones offering greater resistance were struck.
This may be a result of the more frequent lateral impact of the bullet
on these small bones.]
In spite of a considerable experience, I never saw a case of perforation
of either the head or neck of the thigh bone. I saw numerous tracks
emerging at the side of the femoral vessels and entering at the buttock
or vice versa, but never one accompanied either by effusion into the
hip-joint or impairment of movement. Considering the regularity with
which hæmarthrosis occurred when the other joints were crossed, and also
the nature of the compact tissue of the neck of the femur, which must
have ensured some splintering, I do not think I can have overlooked an
injury of this nature. No doubt also the escape of the neck of the bone
was explained in some of the cases by the fact that the injuries were
received while the hip-joint was in a position of flexion, the bullet
passing over the neck of the femur. In two cases of extensive
comminution of the upper third of the femur that I saw, the fissures
stopped short at the inter-trochanteric line anteriorly, but in one of
them a large angular fragment was torn out of the posterior surface of
the neck.
Excepting transverse fracture every form was met with in the shaft,
although I saw only two instances of perforation. One has been already
alluded to and was situated in the broadening portion of the lower
third, the bullet taking an antero-posterior course. The second is seen
in plate XVII.
Plate XII. shows an instance of extreme comminution of the upper third
accompanied by the presence of two typical elongated fragments. The
course taken by the bullet was almost directly antero-posterior, and the
wounds were of moderate size even in the case of the exit one. This
seems to preclude the possibility of the injury having been produced by
a ricochet bullet, while the fact of perforation and escape of the
bullet in spite of the serious damage suffered by the mantle points to
the injury having been produced at a short range of fire. The patient
himself owns to being quite unable to give any estimate of the distance.
Although no suppuration occurred, this fracture was very slow in
consolidating, and the free comminution with consequent inaccurate
apposition led to the development of four inches shortening of the limb.
The skiagram was taken about six weeks after the occurrence of the
injury, a few days after I first saw the patient; I have, however, had
the opportunity of seeing a second skiagram taken some four months
later. This is of considerable interest, as throwing light on the mode
of union of such fractures. The two elongated fragments in the later
skiagram are widened to three times their original breadth, and form
buttresses on either side of the point of union, while the irregular
ends of the shaft are rounded off, and the mass of fine fragments behind
is consolidated. Beyond this the second skiagram shows that the upper
fragment, apparently intact in the first, was really split
longitudinally, and therefore was far less useful as a point of support
than might have been assumed from the earlier skiagram, plate XIII. The
case illustrates well the chief difficulty in the treatment of such
fractures: that of maintaining the fragments in line, since absolutely
no help is received from the apposition of the two ends, and artificial
traction alone must be relied upon.

(31) HIGHLY COMMINUTED FRACTURE OF THE UPPER THIRD OF THE SHAFT OF THE
FEMUR
Range 'short.'
Impact fairly direct. The wounds were of moderate size and at nearly the
same level. The exit wound near the buttock fold was of moderate size,
and presented no special features.
Considerable fragmentation of the bullet occurred. The comminution of
the bone is very fine, suggesting high velocity, and great resistance by
the bone. The skiagram was taken five weeks after the injury was
received, and at that time no union had occurred.
Reference to plate XIII. will explain more fully the difficulty
experienced in maintaining this fracture in position. The upper fragment
is seen to be split into fragments, beyond the separation of the long
splinter on the inner side; hence no aid was to be obtained from the
apposition of the ends. About 2 inches of the shaft were actually
pulverised; the fine fragments seen in a mass to the inner side of the
bone in the exit portion of the back, eventually formed a large mass of
callus, and the fracture united, with considerable shortening.]
Plate XIV. offers a good contrast; the fracture here presents a typical
stellate form, and a good result without shortening was readily
obtained. I assume that the difference in character of these two
fractures depended mainly on the rate of velocity with which the bullet
was travelling, since it passed fairly directly across the limb in each.
I think it is clear, however, that the bullet struck the femur rather
nearer the centre of the width of the shaft and therefore more directly,
in the more severe injury.
This brings me to the question of explosive exit wounds in the thigh. In
spite of the great tendency to comminution of the shaft, these were rare
in a severe form. This depended simply on the depth and thickness of the
coverings of the bone, and, as already mentioned, although the skin
openings were often comparatively small, a large cavity or area of
destroyed soft tissues may be contained within the limb. I do not think
I ever saw an exit wound in the thigh exceeding 1-1/2 inch in diameter.
The oblique fracture illustrated by plate XVI. has been already referred
to, and the influence of the weight and movement of the trunk on its
production has been considered.
Plate XV. illustrates an obliquely comminuted fracture of another
character. The bullet has here been stripped of its mantle, which has
undergone fragmentation, but the leaden core is little altered in shape.
This is of much interest, since it shows that the bullet struck the bone
by its side. The effect of such lateral impact on the part of the
projectile is well shown: there is great bone comminution of a less
regular character than usual, and the bullet is retained. Retention in
this case was probably not a result of low velocity of flight, but of
the increased resistance offered by the broad area of bone struck, and
the check exerted on the axial rotation of the bullet by the lateral
contact.

(31_a_) THE FRACTURE SHOWN IN PLATE XII., SIX MONTHS AFTER RECEPTION OF
THE INJURY
The amount of callus furnished around the loose fragments is very
striking.
The upper end of the bone is shown to have been divided into at least
two fragments, hence one of the difficulties of maintaining the ends in
apposition. The stoppage of the fissuring short of the epiphysis is
characteristic.]
Slighter injuries to the femur in which the shaft was chipped or grooved
without loss of continuity were not uncommon, and showed well the
capacity of the bone to withstand the lateral shock transmitted by small
bullets. Two figures inserted in the chapter on wounds in general (figs.
22, 23, pp. 61, 62) are of cases in which, from the appearance of the
wound of exit, the bullet probably underwent deformation, or was so
deflected as to escape on a considerably altered axis. Beyond the nature
of the exit wound in the case depicted in fig. 22, some thickening
beneath the femoral vessels denoted bone injury, but unfortunately no
skiagram was taken.
I saw no case in which a transverse fracture of the shaft accompanied
such injuries, but am under the impression that, if they had been
produced by bullets of greater volume and weight, transverse solution of
continuity would have been more common. In point of fact, no case of
pure transverse fracture of the femur ever came under my notice.
The diagram depicted in fig. 51, p. 164, is from a sketch made of the
lower end of a femur in which a severely comminuted fracture followed by
suppuration necessitated an amputation of the thigh, performed by Major
Lougheed, R.A.M.C. It is inserted as an illustration of the tendency of
the fissures to stop short above the actual articular extremities of the
bones. In this case the comminution was extreme and accompanied by the
usual long lateral fragments, one of which measured five inches in
length and might well have extended into the knee-joint had that been an
ordinary occurrence.
Perforations of the lower extremity of the bone were very common. These
were sometimes transverse and limited to the articular extremity itself,
or the same limitation occurred to the antero-posterior tracks. These
were the slightest forms of injury, putting on one side incomplete
tunnels and grooves on the surface of the bone. With regard to the
latter, however, when they invaded the joint cavity the injury was
liable to be more severe than a complete perforation, in consequence of
the projection of comminuted fragments into the joint cavity near the
line of reflection of the synovial capsule and ulterior interference
with freedom of movement.

Range 'short.'

Other tracks took a direction of longitudinal obliquity, and then
implicated both epiphysis and diaphysis. Fig. 52, p. 169, shows an
example, and also the peculiarity likely to be assumed by the exit
aperture in the bone, especially if the bullet was travelling at a low
rate of velocity, a considerable plate of the compact bone being driven
out. In some cases these oblique tracks involved both femur and tibia.
They will be referred to again under the heading of injuries to the
joints, and some remarks will also be found there regarding the synovial
effusion so often occurring into the knee-joint in cases of fracture of
the shaft of the bone.
It may be of interest to insert here a few remarks as to the clinical
characteristics of fractures of the femur. First with regard to the
primary signs and symptoms. A very considerable degree of general or
constitutional shock usually accompanied them, and this was perhaps more
constant than in the case of any other injury in the body. This was,
moreover, no doubt increased by the unfavourable conditions in which
patients on the field of battle are situated in regard to transport.
When the patients were brought into hospital some delay in the primary
treatment was often necessary until reaction took place. Local shock to
the part was also a prominent feature. Abnormal mobility was very free
in the badly comminuted cases. Crepitus was often loose, and of 'the bag
of bone' variety. The result of local shock and consequent flaccidity of
the muscles was to reduce the development of primary shortening; in some
cases of severe comminution this was practically nil during the first
day or two, when, with return of tone in the muscles, it sometimes
became very considerable. Swelling of the limb was often very great, and
vascular injury definitely far more common than in the fractures of
civil practice, in consequence, no doubt, not only of the number and
sharpness of the fragments, but also of the force with which they were
driven into the surrounding tissues. The exit segment of the track was
out of all proportion in size to the entry, as a result of the
propulsion of bone fragments through it. This often made the closure of
the exit wound a very protracted event, the track continuing to
discharge a small quantity of bloody serum and fragments of necrosed
tissue for many weeks.

Oblique lateral impact on the part of the bullet, the mantle of which

The comminution of the upper portion of the fracture is very fine; the
bullet has merely cut its way down the lower portion, and one or two
long fragments are separated. The skiagram shows well the result of
lateral impact by the side of the bullet.
Compare this plate with No. VI. as illustrating lesser resistance, and
No. VIII. as illustrating the effect of lower velocity.]
In a large proportion of the cases which were transported for any
distance suppuration occurred; this must have been the case in at least
60 per cent. of the fractures. Suppuration was of the character already
described in the general section, affecting particularly the bone
itself, and accompanied by very marked signs of general infection.
_Prognosis in fractures of the femur._--As regards mortality fractures
in the upper third of the bone proved one of the most formidable
injuries which came under treatment. Suppuration was common, at least 60
per cent. of the wounds becoming infected. This depended on several
reasons, often inseparable from the injuries, or from their treatment in
Field hospitals: such as (1) the exit wound being situated in the
dangerous region of the thigh; (2) ineffective dressing and fixation;
(3) the impossibility of ensuring primary cleansing and removal of
detached fragments of bone; (4) the necessity of the early transport of
patients to the Stationary or Base hospitals, often for great distances;
(5) the comparatively long period that often had to elapse before the
opportunity of doing the first efficient dressing arrived.
Fractures in the middle and lower thirds of the bone were more easy to
treat successfully, but these also added to the list both of amputations
and fatalities.
Punctured fractures of the lower articular extremity were usually of
little importance, as they progressed without exception, as far as my
experience went, favourably.
I can give no idea of the general results obtained during the whole
campaign, but I am able to state the results of the fractures of the
shaft treated at No. 1 General Hospital during my stay in South Africa.
Thirty-two cases of fracture of the shaft of the bone came under
treatment, and of these 6 or 18.7 per cent. needed amputation, and of
the whole number 5 or 15.6 per cent. died. To emphasise the satisfactory
nature of these figures I need only quote the results attained in the
American War of the Rebellion; mortality in upper third, 46 per cent.;
middle third, 40.6 per cent.; lower third, 38.2 per cent.

Aperture of entry just above the centre of the outer aspect of the
thigh. Exit, about 2 inches lower, at the junction of the inner and
posterior aspects. The bullet was retained just within the wound, and
when removed the mantle fell off in two parts. The leaden core was
mushroomed. The bullet had passed through another soldier previous to
entering the patient's thigh. Only two small fragments of the mantle
were retained, as seen in the skiagram. These were in the substance of
the great sciatic nerve, and were subsequently removed by Sir Thomas
Smith.
It is difficult to determine how the bone was struck; reference to plate
XXI. would suggest that the shaft may have been perforated, but no
evidence of this remains in the skiagram taken, which was five months
later.
The patient was standing at the moment of reception of the injury, and
the obliquity of the fracture no doubt depended on his fall and the
resulting influence of the weight of the body. The length of the
fracture cleft was 9 inches.]
I need hardly dwell upon the difference between the nature of the
injuries received in the American War of the Rebellion and in the
present campaign, as in the former the old large bullets were employed,
and shell injuries are possibly included; but I ought to add in this
relation, that the numbers quoted from No. 1 General Hospital included,
to my knowledge, at least three severe Martini-Henry wounds.
The first element for a favourable prognosis is a small wound, and
opportunity for an efficient primary treatment of the same; the second
the absence of necessity for transport of the patient. With regard to
the second of these requirements, we were unfortunately situated in
South Africa, and the majority of the cases which did badly were moved
during the first few days and for a distance of between five and six
hundred miles. On the other hand, as a rule, the external wounds were
small.
As to functional result, the fractures did well. I think an average of
an inch and a half would well cover the shortening, and in many the
length was little altered. Considering the serious nature of many of
these fractures, this was good.
_Treatment._--In all punctured fractures of the lower extremity,
dressing of the wounds like uncomplicated ones and a short period of
immobilisation were all that was necessary. In oblique fractures, and
those with slight comminution, closure of the wound by dressings, after
it had been carefully cleansed, was all that was necessary prior to
applying the splints for immobilisation.

In the highly comminuted fractures a more radical treatment was
indicated, especially if the exit wound was large. In these, after
careful preliminary cleansing of the limb, the wounds, especially the
exit aperture, needed exploration and, if necessary, enlargement, and
all free splinters needed removal. If interference with the entry wound
could be avoided, this was always preferable, as it was rare for this
not to heal by primary union unless free suppuration occurred. Under
Field hospital conditions I think the exit wound should never be
sutured, whatever its situation; and in the present campaign, where
carbolic acid lotion was freely used, this step was manifestly
inadvisable, in view of the abundant serous discharge always to be
expected when this disinfectant has been employed. Except in cases
manifestly infected at the time of exploration, the use of drainage
tubes or plugs is not to be recommended. I would point out also that in
the majority of cases it is quite hopeless to attempt to make the entry
wound the safety-valve for drainage, as its natural tendency, even if
enlarged, is to heal, while the condition of the tissues in the exit
segment of the track usually renders primary union an impossibility.
The wound having been dealt with, the next indications were for the
reduction of deformity, immobilisation of the limb, and the provision of
a proper degree of extension. As to the reduction of the fracture, this
was always a matter of ease, needing only slight axis traction. The
provision of efficient means of extension and immobilisation was a very
different matter. These questions had to be considered under two sets of
conditions: (1) when it was possible to keep the patient at rest in the
hospital he was first deposited in; (2) when it was necessary for him to
be transported for a considerable distance, probably not less than 500
miles.
When transport is a necessity, the best method of immobilisation is the
application of breeches of plaster of Paris, and a long outside splint.
The latter we often had excellently made on emergency by the Ordnance
Department or the Royal Engineers. A perineal band is the only form of
extension possible under these circumstances. The Dutch ambulances were
provided with a very excellent emergency splint for cases of fractured
thigh, which is illustrated in fig. 56. I think something of this kind
should be carried in one of the ambulances going on to every field of
battle, as being far more suitable than a long outside splint for hasty
and inaccurate application. This splint, fixed with some kind of firm
bandage, is an excellent temporary one for use during transport.

[Illustration: FIG. 56.--Dutch Cane Field Emergency Splint for Thigh or
Lower Extremity. (Dutch Ambulance, Winberg)]
In cases which can be treated at a Stationary hospital near at hand, a
long outside splint supplemented by plaster breeches, and a well-applied
American extension, is a very good method of treatment, the only point
to bear in mind being frequent examination of the position of the limb
to ensure the extension being efficient. As already mentioned, the
shortening in the primary stages is often slight and easily combated,
but in many of these cases if examined in a few days the limbs are found
to have shortened considerably, principally as a result of recovery of
tone by the muscles, and the absence of any help from the resting of the
two fragments end to end. The weight, therefore, has often to be
progressively increased and the fracture readjusted if necessary.
Although this method of treatment is satisfactory in cases with a small
wound, it is very troublesome to carry out, even when a bracket is
inserted opposite the wound, when frequent dressing is necessary, as is
generally at first the case when the wounds are large. For this purpose
a much more satisfactory method is the use of Hodgen's splint. This
allows of automatic adjustment of the degree of extension, and the
dressing of the wound without interference with the position of the
fracture. A continuous many-tailed bag is preferable to the strips
usually employed for the suspension of the limb, as more easily
adjustable and as offering a more even support to the limb.

(37) OBLIQUE COMMINUTED FRACTURE OF THE TIBIA

The entrance wound was large and the exit also. The fracture may have
been caused by a Mannlicher (8 mm.) soft-nosed bullet, or possibly a
ricochet. The fragmentation is somewhat coarse at the periphery, but
very fine in the track of the bullet. Several fragments of the mantle
are visible.
The fracture affords a good example of obliquity due to cutting by the
bullet, and contrasts well with those due to rectangular impact such as
are shown in plates IV. and XIV.]
While at Orange River, in conjunction with Major Knaggs, R.A.M.C., and
Mr. Langmore, we treated several cases of fracture of the shaft of the
femur by this method. The splints were made for us by the Ordnance
Department, while the Royal Engineers erected a kind of gallows for us
down the centre of a commissariat marquee in order to avoid the risk of
using the tent poles for suspension. The patients were then ranged on
each side of the tent in two rows so that the pull of the two sets of
limbs opposed each other on the gallows from which they were suspended.
Although these patients had to lie on the ground, they were really
comfortable compared with those treated with long outside splints, and
the results obtained were very good: in three cases which I had the
opportunity of measuring later the bones were in good position and the
shortening was less than one inch.
I have no doubt whatever that Hodgen's splint is by far the best method
of treating all cases of fractured thigh in the Stationary field
hospitals; and, more than this, I believe it is the only practicable and
efficient one. It can be applied without the use of an anæsthetic
without causing undue suffering to the patient, it allows of ready
change of the dressing, it is comfortable and permits considerable range
of movement on the part of the patient, it is as efficient with patients
lying on the ground as in a bed, it keeps the limb in good position and
allows of constant inspection on this point, and it is the only method
which provides satisfactory extension without constant readjustment.

the fibula full. This is the only instance of a transverse cleft which
came under my notice.
The wound suppurated, and a number of fragments of the fibula needed
removal; hence the amount of callus present.]
Cases in which operative fixation is indicated are rare, but a few
oblique fractures may be treated with advantage in this manner if the
conditions surrounding the patient admit of it. Screwing is generally
preferable to wiring.
Lastly, we come to the cases in which primary amputation is necessary. I
may say at once that I saw no case of wound from a bullet of small
calibre in which this was indicated, and only one shell injury in which
it was performed. I believe with small bullets that injury to the main
blood-vessels is almost the only indication which is likely to be met
with, and this by no means always indicates an amputation. First of all
the question arises as to whether the wound in the vessel is caused by a
bone fragment or by the bullet itself; reference to the chapter on
blood-vessels would seem to prove that a bullet wound is by no means a
necessary indication for amputation. Given favourable conditions, it
might be treated locally by ligature at the time, while if hæmorrhage is
not proceeding, developments should be awaited before proceeding to
amputation. In the case of bone fragment punctures, secondary hæmorrhage
is a more likely indication for amputation than primary.
Broadly, it may be laid down that very extensive injury to the soft
parts is the only indication for primary amputation beyond primary
hæmorrhage, and it may be added that the condition is rare with wounds
from small-calibre bullets. If a primary amputation is necessary the
observations as to the transport of fractured thighs are equally
applicable. I never saw a primary amputation do well that was moved
during the first week; sloughing of flaps or hæmorrhage followed as a
rule, and often death.
Intermediate amputations were indicated in cases of septic infection and
those of hæmorrhage; they seldom did well, and should be avoided if
possible. Secondary amputations for sepsis or hæmorrhage were attended
by fair results, but I can give no statistics. Unless extensive
osteo-myelitis is evident, or very widespread cellulitis of the limb
exists, I am strongly of opinion that the amputations when the fractures
are above the middle of the thigh should be through the fracture, and
not at the hip-joint, even if a subsequent secondary operation is
risked.

The patient was standing when struck, and fell backwards, his rifle
falling at the same time and striking the shin. The fibula is intact.
The perforation indicated by the well-marked translucent spot is small.
The forking of the lower extremity of the cleft suggests the starting of
the fissure from above. The fissure comes to the surface at the seat of
election, but its position may possibly have been determined by the blow
from the falling rifle.
The backward fall of the patient clearly explains the mechanism of
production of the fissure, and throws light on the production of an
oblique fracture such as shown in plate XVI.]
_Fractures of the patella._--Punctured fractures of the patella were
common with direct impact of the bullet; these were often difficult to
palpate, and were only to be certainly diagnosed by attention to the
direction of the track, and the development of hæmarthrosis. I saw at
least three or four in which the bullet, in addition to traversing the
knee-joint, injured the popliteal vessels. I have notes of one case in
which a bullet traversed the soft parts from above downwards and scored
a vertical groove on the surface of the patella; this was readily
palpable, but produced no solution of continuity. In several cases the
margin of the patella was notched by a passing bullet.
I never saw a case of stellate fracture, and by this my experience in
the case of the ilium was confirmed.
On two occasions I saw pure transverse fractures of the bone; in each
the wound was produced by a Lee-Metford bullet. This is of some interest
as denoting that the greater volume and weight, in conjunction with the
blunter tip, of the Lee-Metford may produce more severe injury to the
bones than the Mauser. I believe this to be the case, given an equal
degree of velocity on the part of the bullet at the moment of impact;
but it is probable that the position of the patella with regard to the
condyles of the femur when struck is of far greater importance in
relation to the production of transverse fractures. The skiagram
represented in plate XVIII. shows an obliquely transverse fracture,
which in this instance resulted from a crossing bullet, which grooved
the surface of the bone.
With regard to the two cases of transverse fracture above referred to, I
may add that one occurred in a youth under twenty, and a good result was
obtained by treatment with splints, and later by massage. In the second
the patient was a man over fifty, who had received other injuries. The
wound over the patella healed and some union had occurred, when the
patient fell and burst both the bone union and the skin cicatrix.
Secondary suppuration of the knee-joint, necessitating an amputation of
the thigh, followed, but the patient made a good recovery. The third
case also did well.

Range 'short.'
The raising of the margins of the notch suggests a perforation. Compare
with figs. 51 and 57 in the text.]
The treatment of these injuries differed in no way from that adopted in
civil practice, given satisfactory surroundings. Suture might be
indicated in some cases of transverse fracture, but this would only be
necessary if the fragments were widely separated. The punctured
fractures needed treatment as for simple wounds, combined with a short
period of rest and pressure for the condition of hæmarthrosis. It was
important not to prolong the period of rest beyond a week or ten days if
the effusion was slight, in view of possible ulterior interference with
range of movement in the knee-joint.
_Fractures of the tibia._--Some remarks have already been made regarding
fractures of the head of the tibia, and the importance of the
overhanging prominent margins in the production of somewhat irregular
injuries (p. 170). Putting these peculiarities on one side, the
cancellous ends are subject to the type forms of injury; thus
perforations either of the head of the bone or the malleolus were common
injuries. The fractures of the shaft also deviated from the type in so
far as the broad flat surfaces in the upper two thirds of the bone
rendered it especially liable to the results of lateral impact, and to
the production of the extreme wedge-shaped types of fracture. Plate
XXII. illustrates the different result of a bullet striking the dense
and strong spine at a low rate of velocity, a notch only resulting. If,
on the other hand, the lateral surfaces were struck, a wedge with the
base corresponding to the posterior surface was the most common injury,
the spine in many cases remaining intact and maintaining the continuity
of the bone. Wedge-shaped fractures of this bone were apt to show
multiple secondary wave fissures concentric with the main line, and
consequently free comminution. I saw several examples, the loose
fragments being remarkably numerous. Plate XIX. is an example of an
oblique fracture produced by a bullet which has ploughed across the
bone, displacing large fragments anteriorly, but finely comminuting the
bone in its course, and leaving small fragments of the mantle on its
way. Plate XX. is an example of the rare condition of transverse
fracture.

(41) SPURIOUS PERFORATION OF THE FIBULA
Moderate range, 'about 1,000 yards.'
The injury was caused by an 8 mm. bullet, which entered base foremost
and lodged in the calf. The fracture is really an incomplete stellate
form, two well-marked transverse fissures extending from the point
struck. The position of the bullet suggests its entry into the limb base
foremost, and as it is retained low velocity may be assumed.]
This fracture was produced by a bullet travelling at a high rate of
velocity, which struck the posterior surface of the tibia, and caused a
grooving, accompanied by a horizontal fissure through the whole
thickness of the bone; later it struck the fibula more directly, and
produced an ordinary comminuted fracture two inches above the malleolus.
Perforations of the shaft were far more common than in the case of the
femur, and I saw them in every part of the length of the bone (plate
XXI.). Fig. 57 illustrates a form of peculiar interest as showing the
gradual transition of the tunnel to the groove, and also as bringing
fractures of the long bones into line with such fractures of the flat
bones of the skull as are depicted in fig. 68.
[Illustration: FIG. 57.--(42) Perforation of lower third of Tibia,
showing lifting and fissuring of the compact roof of the tunnel. Compare
with fig. 68, p. 259, of a fracture of the cranial vault.]
_Fractures of the fibula_ offered no special features of importance. Any
form might occur. The plate No. XXIII. is of interest as showing a
spurious form of perforation, and also the primary form of displacement
of the fragments in stellate fractures. It was produced by a reversed
ricochet, but undeformed, bullet, still seen in position in the
skiagram; the bullet only possessed sufficient force to perforate the
bone, and then appears to have turned on its transverse axis. The
following plate, No. XXIV., is inserted to show the depth at which the
bullet lay, and its distance from the surface of the tibia, which
appears in the first plate to be nil. It is also of interest as showing
the ease with which a false impression may be obtained from a single
picture, as, beyond a spot of transparency, no obvious injury to the
fibula, and certainly no displacement, is discernible.
[Illustration: PLATE XXIV.

(41_a_) This skiagram is inserted to show the depth at which the bullet
lay from the surface. It is also interesting to note the insignificance
of the fracture of the fibula from this aspect. Without the second
skiagram the injury might have passed for a simple perforation or a
transverse fracture.]
Fractures of the bones of the leg possessed an unenviable degree of
importance. First, on account of the very severe injuries to the soft
parts that often accompanied them, without an apparently correspondingly
serious damage to the bone. Secondly, on account of the frequency with
which the vessels were implicated in these injuries to the soft parts,
either by the bullet or bone fragments. Beyond this, fracture of either
articular end of the tibia was certainly more frequently followed by
troublesome joint complications than occurred in the case of any other
bone.
In the matter of 'explosive' injuries, I think more were seen in the
calf of the leg than in any other part of the body, and this often
without solution of continuity of the bones, and sometimes without
evidence even of contact of the bullet with either tibia or fibula. Some
remarks on this subject have already been made in the chapter on wounds
in general, and some sources of fallacy exposed. I believe that in
practically all these so-called explosive injuries the wound was either
caused by a ricochet, or a bullet which deformed with great ease on bony
contact during its progress through the limb. A considerable number of
the wounds which were referred by the men to the use of expanding
bullets were probably the result of the use of Martini-Henry or large
leaden sporting bullets, and evidence of this was often forthcoming on
examination of the entry wounds. In other cases the irregularity of the
opening plainly pointed to ricochet of a small bullet as the explanation
of the character of the injury. The greater frequency of ricochet
injuries in the leg and foot when the men were standing is readily
understood.
Concurrent injury to the vessels of the leg was common, but primary
hæmorrhage, as was the case generally, usually ceased spontaneously. The
importance of injury to the vessels was rather in view of secondary
hæmorrhage, which occurred with some frequency, and I think more
commonly from the anterior than the posterior tibial vessels, usually
occurring at the end of a week or ten days, and naturally most
frequently in cases which suppurated.
_Prognosis and treatment in fractures of the leg._--In fractures of the
leg, except those of extreme severity, almost any form of splint
sufficed to maintain the bones in position, but for field purposes the
Dutch cane splint (fig. 58, p. 222) was certainly very convenient. For
later use in cases that needed frequent dressing, a wooden back splint,
with a foot-piece, or, if obtainable, a Neville's splint with a
suspension cradle, was the best. Where the wounds were small and
frequent dressing was not required, nothing was so good as plaster of
Paris, especially when transport was a necessity.
[Illustration: FIG. 58.--Dutch Cane Field Emergency Splint for Leg]
In cases with large wounds suppuration was very frequent, and in
connection with this secondary hæmorrhage, or in the case of fractures
near the articular ends, especially the upper, joint suppuration. The
treatment of these cases varied: in many an amputation was the best or
only treatment advisable; but I several times saw good results follow
ligation of the anterior tibial artery for secondary hæmorrhage, even
when suppuration existed, and occasional good results after incision
and drainage of joints if the infection was not of the most acute form.
Primary amputation was rarely needed for any case of injury from a
bullet of small calibre, since it was only necessary either in the case
of injury to both main arteries, and this was rare, or in cases of very
extensive injury to the soft parts. I saw many of the latter make fair
results when treated conservatively, even though the condition seemed
almost hopeless at first sight. All the primary amputations that I saw
were either for shell or large bullet injuries. A word may be inserted
here as to the weight that ought to attach to nerve injuries in this
relation. From the experience gained elsewhere it is clear that we
should attach little importance to these unless the divided nerves are
actually in sight, as far as deciding on amputation is concerned. On the
other hand, there is little doubt that the presence of concurrent nerve
injury, be it only concussion or contusion, exerts an important ulterior
influence on the healing of the wound, whether the part be amputated or
not. Amputation flaps in such cases possess a very considerably lowered
degree of vitality.
Secondary amputations were often needed for sepsis, and on the whole did
very well; both for the same cause and for hæmorrhage intermediate
amputations had occasionally to be performed; the results of these, as
elsewhere, were bad.
_Fractures of the tarsus._--Wounds of these short bones were as a rule
of slight importance, given fairly direct impact on the part of the
bullet. They then consisted of either simple perforations or surface
grooving. A single bone might be implicated or several might be
tunnelled; in the latter case the implication of the joints very
considerably influenced the prognosis, since the addition of the joint
injury caused much more prolonged weakening of the foot.
Wounds of the foot were common from the fact that when the men lay out
in the prone position, the foot was often the part least protected by
the cover chosen, and particularly the heel. In these circumstances the
os calcis was the bone most frequently implicated, and that by tracks
taking an oblique course downwards from the leg to the sole. Again the
foot was often struck by ricochet bullets, as a result of its position
when the erect attitude was assumed. The latter fact was of much
importance with regard to the nature of the injury sustained by the
bones, as under these circumstances the mode of impact was irregular,
and consequently comminution was often produced.
The behaviour of the different bones of the tarsus varied somewhat. On
the whole the prognosis in cases of injury to the os calcis was the
best, since the injury was more often individual and did not implicate
any joint, and also because of the comparatively regular architecture of
the bone. In the smaller bones concurrent injury to a joint was more
frequent. In the astragalus the central hard core extending upwards from
the interosseous groove, as increasing resistance, I think accounted for
the fact that comminution was more marked in this bone than in any
other. The effect of wound of bones of the tarsus in producing a certain
degree of laxity in the mediotarsal joint resulting in a slightly flexed
position of the fore part of the foot and some projection of the head of
the astragalus did not seem to me easy of explanation, but it occurred
with some regularity.
The injuries to the _metatarsus_ corresponded so nearly to those already
spoken of in the case of the metacarpus that they need no further
mention. They were less common, however, and I am under the impression
that fragmentation of the bullet was not such a marked feature, probably
on account of the lower degree of density of the bones, and their
greater fixity of position.

CHAPTER VI
INJURIES TO THE JOINTS
Until recent times gunshot injuries of the joints formed a class
entailing the gravest anxiety to the surgeon, both in regard to the
selection of primary measures of treatment and in the conduct of the
after progress of the cases. The external wounds were severe,
comminution of the bones was great, and retention of the bullet within
the articulation was not uncommon. Operative surgery therefore found a
large field in the extraction of bullets, removal of bone fragments,
excision of the joints, or even amputation of the limbs.
The introduction of bullets of small calibre has robbed these injuries
of much of the importance they possessed in earlier days and during the
present campaign direct clean wounds of the joints were little more to
be dreaded than uncomplicated wounds of the soft parts alone. No more
striking evidence of the aseptic nature of the wounds, and the harmless
character of the projectile as a possible infecting agent, than that
offered by the general course of these injuries in this campaign, is to
be found in the whole range of military surgery.
The aseptic nature of the wounds, and the slight and localised character
of the bone lesions, have in fact justified the opinion previously
expressed by Von Coler, that these injuries in the future would be less
feared than fractures of the diaphyses of the bones.
Not less important than the localised character of the bone lesion
itself is the fact that the accompanying wounds of the soft parts retain
the small or type forms. Thus I occasionally observed more troublesome
results from minor shell wounds in the neighbourhood of joints, but not
implicating the synovial cavity, than in actual perforating injuries
produced by bullets of small calibre.
_Vibration synovitis._--Before proceeding to the consideration of wounds
of the joints, a short account is necessary of a condition of some
importance which is, I believe, more or less special to injuries from
bullets of small calibre travelling at high rates of velocity. This
condition, if not novel, at any rate excited little comment in the
descriptions of the older forms of injury, although this may have
depended on the more serious nature of the primary local lesions
accompanying wounds from the larger bullets, among which it formed a
comparatively unimportant element.
The condition referred to was the occurrence of considerable synovial
effusion into the joints of limbs in which the articulation itself was
primarily untouched. These effusions sometimes occurred even when the
soft parts alone were perforated, especially when the wounds were
situated above or below the knee-joint. They were apparently the direct
result of vibratory concussion of the entire limb dependent on the blow
received from the bullet.
The effusions were most strongly marked in cases of fractures of the
diaphyses, although this was more noticeable in some situations than
others. Thus with fractures of the shaft of the femur anywhere below the
junction of the upper and middle thirds of the bone, and in some cases
even higher, effusion into the knee-joint was very common, and sometimes
extreme. On the other hand, similar effusions into the hip-joint were
less marked, since I failed to determine their existence in the majority
of cases. I am inclined to ascribe this to the different anatomical
arrangement of the two joints, particularly to the fact that the head of
the femur is included in a bony cup, into the hollow of which it is
accurately fixed by the resilient cotyloid fibro-cartilage. The latter
by its firm grasp of the head allows of little play in the joint; hence
vibrations are conveyed directly to the acetabulum in continuous waves,
and rocking of the articular surfaces is prevented. Beyond this no doubt
the difficulty of detecting small effusions in this joint is an element
which must be taken into consideration.
I do not think that wrenches of the knee-joint in the act of falling
can be suggested as an explanation of the frequency of effusions into
that articulation, since the fractures of the femur were not always
received while the erect position was maintained, and effusion was most
marked when the diaphysis was the part affected, the latter point
illustrating the greater resistance offered by compact bone. Again, when
fracture had taken place, the solution of continuity rendered the
directly injured point the most mobile, and tended to prevent lateral
strain from falling on the joints.
Effusion into the knee or ankle, or sometimes both joints, was common in
fractures of the shaft of the tibia.
In the articulations of the upper extremity the condition was also
common, but somewhat less marked than in the lower limb. Effusions into
the shoulder or elbow occurred. In the former these were less striking;
again, perhaps, as a result of the difficulty of detecting small
effusions in this situation. The elbow was to a certain extent protected
by the possession of a degree of fixity somewhat resembling that already
mentioned in the case of the hip-joint, although here depending on the
conformation of the bones alone. I think this explained the absence of
free effusion in many cases of fracture of the humeral shaft, but when
the latter affected the lower third effusion into the elbow was usually
abundant.
The lighter weight and greater mobility of the upper extremity as a
whole, as decreasing the resistance to the bullet, were also probably an
element in the fact that these effusions were less severe than those in
the joints of the lower limb.
The nature of the effusions was apparently simple, since they were
rapidly reabsorbed, and little thickening of the synovial membrane
remained to suggest either a marked degree of inflammation, or the
deposition of blood-clot on the inner aspect of the same.
The only treatment indicated was a short period of rest, accompanied in
the early stages by pressure and slight fixation, followed later by
massage and movement if necessary.
Before dismissing this subject, I should like to particularly emphasise
the fact, that in the cases described there was no reason to suspect the
extension of fissures from the point of fracture in the shafts into the
articular ends of the bones. This was as far as possible excluded by
clinical examination, and in the cases where wounds of the soft parts
only were present, the rapid return of the patients to active duty, with
absence of remaining joint trouble, negatived the possibility of such
fractures.
I only saw one case in which a longitudinal fracture actually extended
for any considerable distance into a neighbouring joint. In this a
comminuted fracture occurred just above the centre of the shaft of the
humerus. At the time of examination and putting up of the fracture there
was considerable swelling of the whole arm, and nothing special was
noticed about the shoulder-joint. Three weeks later, however, when the
fracture was consolidating, difficulty in abduction of the shoulder was
noted, and the arm could not be placed closely in contact with the
trunk. There was no evident displacement of the head of the humerus
forwards. A skiagram, which I much regret I have not been able to
insert, showed that a longitudinal fissure extended from the seat of
fracture upwards in such a manner as to divide the upper fragment into
two parts, of which the outer bore the greater tuberosity, the inner the
articular surface of the head. The latter fragment had become somewhat
displaced downwards, and had united in such a manner that the head
rested on the lower part of the glenoid cavity. Abduction of the limb
therefore brought the greater tuberosity into contact with the acromion
process, and movement was checked. This case passed out of my
observation shortly afterwards, and I have no knowledge of the final
result as to movement.
Fractures of the bony processes surrounding the elbow-joint, and of the
malleoli of the tibia and fibula, were not infrequent, but offered no
special features.
One other form of injury indirectly affecting the joints is perhaps
worthy of mention, but I observed it only once, and that in the case of
the shoulder, the only joint where it is likely to be marked. I refer to
the displacement of the head of the humerus by the force of gravity,
when the circumflex nerve is injured. In the instance I refer to, a
fracture of the surgical neck of the humerus was accompanied by
complete motor paralysis of the deltoid and very rapid wasting of the
muscle. Circumflex sensation was impaired, but not absent at the time
the condition of the muscle was noted--a favourable prognostic sign of
much importance. At the end of five weeks, when the fracture of the bone
was consolidated, the head of the humerus had dropped vertically at
least an inch, but could be replaced with ease. Shortly afterwards an
improvement in the condition of the muscle commenced, and with this the
head of the humerus was gradually raised. This patient later recovered
his power in great part, but not completely.
In a few cases bullets lodged in the neighbourhood of joints in such
positions as to limit movement by mechanical impact with the bones. Thus
I saw one case in which a bullet lay between the radius and ulna just
below the lesser sigmoid cavity; in another the bullet lay in front of
the ankle-joint, and limited the possibility of flexion; and in a case
related to me by Mr. Bowlby, a bullet was removed by him from the wall
of the acetabulum where it was tightly fixed in the substance of the
bone. In two other cases I saw bullets lying deeply on the anterior
surface of the hip capsule and so limiting flexion. In all such cases
the indication for removal of the bullet was sufficiently strongly
marked.
WOUNDS OF THE JOINTS
These may be divided into several classes, varying much in comparative
severity, and in prognostic importance.
1. The comparatively rare instances in which a wound implicated a joint
cavity, without accompanying lesion of any bone.
2. Perforating wounds in which the bullet was retained within the
articular cavity. These were also rare.
3. Wounds of the joints accompanied by grooving of the articular
extremities of the bones.
4. Complete perforating tracks through the articular ends of the bones,
crossing the joint cavity in various directions.
5. Comminuted fractures of the terminal parts of the diaphyses extending
into joints.
Of these several classes, the first was of the least prognostic
importance. In the absence of bone injury the wounds usually healed
without any obvious ill effect beyond the transient effusion into the
joints of a mixture of blood and synovial fluid. When suppuration of the
wound in the soft parts occurred, however, the remarks made as to the
injuries classed under the third heading also apply here in a lesser
degree.
With regard to the retention of the bullet, in the case of bullets of
small calibre this was a distinctly rare occurrence. I never happened to
see an instance of retention of either a Mauser or Lee-Metford bullet in
an articulation. It is only possible with bullets practically spent, or
travelling at a very low rate of velocity and making irregular impact.
The influence of both volume and velocity of flight was well illustrated
by my own small experience of retained bullets. In one case a
Martini-Henry was found impacted between the femoral condyles, having
slipped in beneath the margin of the patella. It caused a semiflexed
position to be assumed by the joint, and was removed by Mr. Brown in No.
1 General Hospital at Wynberg. The second instance I saw in the Portland
Hospital at Bloemfontein in a patient of Mr. Bowlby's. The bullet was a
Guedes, a form which has been already described as possessing low
velocity and deficient power of penetration; beyond this, in the
particular instance irregular impact was evidenced by the presence of a
large irregular contused wound of entry over the tuberosity of the
tibia.
The presence of the bullet in the knee-joint was later determined by the
X-rays, and Mr. Bowlby removed it successfully. Seven months later the
range of movement was nearly normal.
I may add that I saw several instances of large leaden bullets lodging
in the popliteal space, and a comparatively insignificant number of
bullets of small calibre in the same situation. This was very striking,
in view of the immense relative frequency of use of the latter forms.
There is no doubt, moreover, that small bullets rarely lodge even in the
neighbourhood of joints, unless at the distal end of a long track. To
take the extreme example of large bullets, those employed as shrapnel,
in comparison with the frequency with which wounds were produced by
them, bullets lying at the bottom of short tracks in the neighbourhood
of joints were not uncommon. Thus I saw one lying over the hip-joint,
and another in close proximity to the shoulder capsule.
Wounds of the third class, where the bones had been superficially
grooved, were in some respects the most serious. This was especially so
in the knee and ankle joints, and some cases will be quoted later under
the heading of the special joints to illustrate this point. Danger only
arose in the event of suppuration; and here the presence of the long
oblique superficial track in a neighbourhood liable to comparatively
free movement was the important element. Such tracks usually opened the
synovial sac more extensively than direct perforating wounds, and if
suppuration occurred in any portion of the track, the pus was very
liable to be sucked into the joint on any free movement. The presence of
fine splinters of the bone displaced in the production of the groove was
also a special character of wounds of this class. Another point worthy
of mention is that in these cases it was not always easy to be quite
certain whether the joint cavity had been implicated or not, since cases
often occurred in which, although the bones had been grooved, the joint
cavity escaped. The indication, however, was to consider any wound in
the immediate proximity of a joint as perforating until it was healed.
This course was the more easy to take, since a large proportion of such
wounds were accompanied by some degree of synovial effusion, even when
the neighbouring joint had escaped puncture.
Wounds of the fourth class, although the most highly characteristic of
the form of accident, were in many instances the most favourable in
regard to their course. The tracks might course directly across the
joint in any direction, or they might course obliquely, traversing
either one or both the component bones. In the latter case the exit
might be in the diaphysis, and be accompanied by the separation of an
exit fragment such as is illustrated in fig. 52, p. 169. The
particularly favourable character of the direct transverse and
antero-posterior wounds depended on the slight amount of splintering of
the bones, the limited nature of the opening into the joint, and the
shortness of the tracks in the soft parts, which ensured that, even if
infection did occur, the resulting pus was near the surface, and
generally spread in that direction and escaped.
Wounds of the fifth class were the most dangerous, but the danger was
entirely a secondary one, dependent on the occurrence of infection.
These injuries were liable to be accompanied by the presence of
extensive irregular wounds of the soft parts, in which suppuration was
frequent, and the suppuration of the joint frequently meant subsequent
amputation, if not a worse result.
_Course and symptoms of wounds of the joints._--The immediate result of
any perforation of a joint was the development of intra-articular
effusion. This consisted of synovial fluid admixed with a varying
proportion of blood. The degree of synovitis was apt to vary with the
amount of force expended in the production of the injury; for this
reason both high velocity and irregular impact were of importance in
this relation.
The constant feature, however, depended on the effusion of blood; this
was not rapid, or, as a rule, very abundant, but tended to increase
during the first twenty-four hours. It resulted in a swelling of the
joint, which possessed some peculiar features. At first elastic and
resilient, it slowly decreased in volume with the assumption of a soft
doughy character on palpation. In the case of the knee, where readily
palpated, it very much resembled a tubercular synovial membrane, except
for its extreme regularity of surface; still more closely the condition
noted in a hæmophilic knee of some duration. Absorption took place with
some rapidity, and except for slight thickening, the joints might appear
almost normal, in a period of from two to four weeks. With the
development of the effusion there was local rise in temperature of the
surface, and in a considerable number of the cases a general rise of
temperature.
This latter was sometimes very marked, as in the case of all the other
traumatic blood effusions, but not quite so regular in occurrence. It
was important, as I have seen it give rise to the suspicion of
suppuration, when tapping resulted in nothing more than the evacuation
of turbid synovia mixed with blood. Pain was rarely a prominent symptom
in consequence of the generally moderate degree of distension.
As a rule, these injuries were characterised by the small tendency to
the development of adhesions; but this in great part depended on the
care expended on their treatment. If kept too long quiet, either from
necessity when the effusion was followed by much thickening, or when the
external wound was large and so situated as to be harmfully influenced
by movement, or in the ordinary course of treatment, troublesome
stiffness, even amounting to firm anchylosis, sometimes followed. I saw
several such cases, some of the most confirmed being wounds of the
knee-joint complicated by injury to the popliteal vessels or nerves. The
latter complication I saw altogether six times, but only once with a
thoroughly bad knee, and in this case the injury had affected both the
vessels and the internal popliteal nerve. The joint in that case was
straightened out by continuous extension by Major Lougheed, when it came
under his charge some six weeks after the primary injury, but I hear has
again relapsed, and the popliteal paralysis is not much improved.
The small tendency to formation of adhesions in uncomplicated cases
probably depended on the coagulation of a layer of blood over the whole
internal lining of the joint. This kept the synovial surfaces apart at
the lines of reflection of the membrane, and, given sufficiently active
treatment, mobility was restored before any firm union could take place.
The primary escape of synovial fluid was rarely observed, as the wounds
of the soft parts were too small and valvular to permit of it. Synovia
in some abundance, mixed with pus, sometimes escaped in considerable
quantity when infection had opened up the tracks.
Primary suppuration in any joint as a result of small and direct wounds
was very rare. I observed it only on one occasion. On the other hand, a
considerable number of cases in which secondary suppuration occurred
came under my notice. In some of these the suppuration was secondary to
comminuted fractures of the shaft of the tibia, in which the articular
extremity was implicated. These offered no special peculiarity. In
others infection of the joint was secondary to infection and suppuration
in the deep part of long oblique wound tracks, and these were of
sufficient interest to warrant the insertion of two illustrative cases.
(43) In a man wounded at Paardeberg the bullet entered the leg
to the inner side of the crest of the tibia, about 3 inches
below the tubercle; thence it coursed upwards to emerge about 2
inches above the cleft of the knee-joint on the outer side.
Regulation dressings were applied, and a week later the man
arrived at the Base, with little apparent mischief in the
knee-joint. He was placed in bed and warned against movement;
on the second day, however, he got up and walked to the
latrine. When bending his knee to sit down he was seized with
agonising pain in the joint, and had to call out for help; he
was then carried back to bed in a more or less collapsed
condition. The knee commenced to swell; there was rise of
temperature and great pain, together with extreme restlessness.
I was asked to see him two days later, and after a
consultation, Major Burton, R.A.M.C., freely incised the
knee-joint bi-laterally. One opening was closed, the second
plugged for drainage, as there was a large quantity of pus. No
improvement followed, and a week later Major Burton amputated
through the thigh. An attack of secondary hæmorrhage a few days
later, combined with the degree of septic infection, ended the
man's life. On examination of the joint, a groove forming
three-fourths of a tunnel was found in the external tuberosity
of the tibia, leading into the knee-joint beneath the external
semilunar cartilage. The bullet had then passed upwards over
the outer border of the cartilage, bruised the margin of the
external condyle of the femur in such a manner as to depress
the outer compact layer, and finally escaped from the joint
near the upper reflection of the synovial membrane. The
synovial membrane was granular in appearance and reddened, but
there was no suppuration outside the confines of the joint,
except in a cavity corresponding to 2 inches of the track
before it actually perforated the tibia. A localised abscess
had evidently formed here and been diffused into the joint by
the movement of flexion already described.
(44) A man wounded during General Hamilton's advance on
Heilbron was struck on the outer aspect of the heel. An oval
opening of some size led down to a track in the os calcis; the
bullet was retained. The foot was dressed, and put up later in
a plaster-of-Paris splint. On the tenth day the splint was
removed to see to the wound, which looked satisfactory and was
re-dressed.
A few hours later the man was seized with very severe pain in
the ankle, and a day later I was asked to see him by Mr.
Alexander. The man was anæsthetised, and I examined the wound
with care, and also removed the retained bullet from the inner
margin of the leg. The bullet was reversed, having no doubt
suffered ricochet, hence the large aperture of entry, but it
was in no way deformed. I could not certainly determine the
presence of any fluid in the ankle-joint, and as the pain was
apparently localised to the distribution of the
musculo-cutaneous nerve, I decided not to freely open the
joint. In this, however, I erred, and two days later, after
consultation, the joint was freely incised by Mr. Alexander. It
was then found that the bullet in its passage had just touched
the posterior aspect of the tibia and wounded the ankle-joint.
A localised collection of pus which had formed in the deep part
of the wound had been diffused into the joint by the movements
made when the splint was removed, in a similar manner to that
described in the last case. This joint also did badly, and an
amputation of the leg had to be performed by Mr. Alexander to
save the man's life.
These two cases are particularly instructive as showing, first, how
quietly a small amount of deep suppuration may sometimes take place;
and, secondly, the importance of keeping the joints quiet on a splint
when there is any reason to suspect their implication by wounds of this
character.
_The general treatment_ of the wounded joints was simple. The old
difficulties of deciding on partial as against full excision, or
amputation, were never met with by us. We had merely to do our first
dressings with care, fix the joint for a short period, and be careful to
commence passive movement as soon as the wounds were properly healed, to
obtain in the great majority of cases perfect results. Careful light
massage, if available, was used to promote absorption of blood.
If suppuration occurred, the choice between incision and amputation had
to be considered. In the early stages this choice depended entirely on
the nature of the injury to the bones. If this were slight, incision was
the best plan to adopt. I saw several cases so treated which did well,
although convalescence was often prolonged, and only a small amount of
movement was regained. Amputation was sometimes indicated in cases of
severe bone-splintering, when the shafts were implicated, but was as a
rule only performed after an ineffectual trial to cut short general
infection of the septicæmic type by incision.
I have dwelt at such length on the subject of suppuration on account of
its importance, but I should add that, on the whole, suppuration of the
joints was uncommon, except in the case of injuries far exceeding the
average in primary severity.
_Special joints._--Such deviations from the general type of injury as
above described depended entirely on peculiarities of anatomical
arrangement, and peculiarities in the situation of the joint clefts in
the different parts of the body. A few words as to these are perhaps
necessary.
_Shoulder-joint._--Wounds of this articulation were by no means common.
This depended, I think, on two points in the architecture of the joint:
first, a bullet to enter the front of the cavity and traverse the joint
needed to come with great exactitude from the immediate front; secondly,
wounds received from a purely lateral direction calculated to pierce the
head of the humerus and the glenoid cavity were naturally of very rare
occurrence. Wounds of the prominent tip of the shoulder received while
the men were in the prone position were not uncommon, but it was
remarkable how rarely the shoulder-joint was implicated in these. The
question of the narrow nature of the cleft exposed also comes up in this
position. As far as my experience went, injuries to the lower portion of
the capsule accompanying wounds of the axilla were those most often met
with. The ease and neatness with which pure perforations of the head of
the humerus can be produced was also an important element in the
frequent escape of this joint. No case of fracture of the glenoid cavity
happened to come under my notice.
I saw few instances in which the joint needed incision, and cannot
recall or find in my notes any case in which serious trouble arose.
_Elbow-joint._--Injuries to this joint came second in frequency in my
experience to those of the knee. They were, in fact, comparatively
common, especially in conjunction with fractures of the various bony
prominences surrounding the articulation. Fractures of the lower end of
the humerus were of worse prognostic significance than those of the
ulna, on account of the greater tendency to splintering of the bone. I
saw several cases of pure perforation of the olecranon without any signs
of implication of the elbow-joint. In a case which has been utilised for
the illustration of some of the types of aperture (fig. 20, p. 59), at
the end of a week there was no sign of any joint lesion, although the
bullet had obviously perforated the articulation.
Several cases of suppuration which came under my notice did well. I saw
one of them a few days ago, six months after the injury, with perfect
movement. In another of which I took notes, the bullet entered over the
outer aspect of the head of the radius, to emerge just above the
internal condyle anteriorly. A considerable amount of comminution of the
olecranon resulted, and when the man came into hospital some ten days
later the joint was suppurating. The joint was opened up from behind,
and some fragments of bone removed by Mr. Hanwell. On the 26th day this
joint was doing well, and considerable flexion and extension were
possible without pain. There was a somewhat abundant discharge of bloody
synovia during the first few days after the operation.
[Illustration: FIG. 59.--Illustrates the very neat and limited injury to
the Phalanges over the dorsal aspect of the first inter-phalangeal joint
of the Middle Finger, accompanying a gutter wound received by the
patient while holding a rifle.]
I never saw any troublesome results from perforations of the _carpus_.
The joints of the _fingers_ also offered little special interest,
except in so far as they afforded astonishing examples of the extreme
neatness of the injuries which a small-calibre bullet can produce. Fig.
59 is a good example of such an injury.
_Hip-joint._--I can only repeat with regard to this joint what I have
already said as to the injuries to the head of the femur. I had
practically no experience of small-calibre bullet injuries to the
femoral constituent, and beyond the single case of injury to the
acetabular margin mentioned on p. 193 I saw no obvious wounds of the
joint at all.
_The knee_, as usual, proved itself _par excellence_ the joint most
commonly injured, no doubt as a result of its size, the extent of its
capsule anteriorly, and its exposed position. In spite, however, of the
frequency with which it suffered injury, and the opportunities it
afforded for observation of the progress of the effusions towards
absorption, the injuries to the joint gave less anxiety and attained a
more favourable prognostic character than is the case in civil practice.
This depended on the very favourable course observed in the frequent
pure perforations following a direct line. These occurred in every
direction, the accompanying hæmarthrosis usually disappearing completely
in an average period of little over a month. The extremes can be fairly
placed at a fortnight and six weeks. Limitation of movement was slight
or non-existent in many cases; in others it was of a very moderate
character, and I only remember to have seen one case in which a really
serious anchylosis developed. In this the man was struck from a distance
of 300 yards, and a considerable amount of bone dust from the femur was
found in the lips of the exit aperture. The wounds healed _per primam_,
but when I saw the man two months later anchylosis in the straight
position was apparently complete.
The comparatively frequent association of popliteal aneurisms with
wounds of the knee-joint has already been spoken of in relation to
anchylosis. Wounds of the popliteal space from larger bullets sometimes
caused more troublesome after-stiffness than wounds of the articulation
itself. Again I remember a small pom-pom wound at the inner margin of
the ligamentum patellæ without obvious wound of the joint, which was
accompanied by synovitis from contusion, and was followed by very
considerable limitation of movement. This had only been partially
improved when the patient returned home, in spite of prolonged massage
and passive movement.
The general remarks on the joints cover all that need be said as to
suppuration of the knee-joint.
_The ankle-joint_ maintained the undesirable character which it has
always held as a subject for gunshot injuries. This is entirely a
question of sepsis, and in great measure depends on the fact that the
foot, as enclosed in a boot, is invested with skin particularly
difficult to thoroughly cleanse; while the socks are an additional
source of infection to the wounds before the patients come under proper
treatment.
Of seven cases of suppurating ankle-joint, of which I have notes, only
two retained the foot, and one of these after a very dangerous illness.
This case was one of special interest as exemplifying the results
dependent on variations in velocity on the part of the bullet. The
patient was struck at a distance of twenty yards. The bullet entered the
front of the right ankle-joint and emerged through the internal
malleolus, just behind its centre, causing no comminution of the latter.
It then entered the left foot by a type wound one inch behind and below
the tip of the internal malleolus, traversed and comminuted the
astragalus, and emerged one inch below the tip of the external
malleolus. The first joint healed _per primam_. The second produced by
the bullet when passing at a lower rate of velocity was accompanied by
considerable comminution of the bone. It suppurated, and gave rise to
great anxiety both for the fate of the foot and the life of the patient.
It is probable that the more abundant hæmorrhage which took place from
the second wound was in part responsible for the occurrence of
infection.
The second of the two cases is of some interest in relation to the
doctrine of chances as to the position in which a wound may be received.
The man was wounded in one of the earlier engagements, a bullet passing
transversely through his leg immediately behind the bones and about half
an inch above the level of the ankle-joint. He recovered, and rejoined
his regiment, only to receive at Paardeberg a second wound, about an
inch lower, which traversed the ankle-joint. On his return to Wynberg he
happened to be sent to the same pavilion, and occupied the same bed he
had left on returning to the front.
The subject of the result of wounds of the joints of the _foot_ has
received sufficient consideration under the heading of wounds of the
tarsus.
The repetition of the fact that, among the whole series of cases on
which this chapter is founded, not a single instance of primary or
secondary excision of a joint, either partial or complete, is recorded,
forms an apt conclusion to my remarks on this subject.
CHAPTER VII
INJURIES TO THE HEAD AND NECK
Injuries to the head formed one of the most fruitful sources of death,
both upon the battlefield and in the Field hospitals. It has been
suggested that the mere fact of wounds of the head being readily visible
ensured all such being at once distinguished and correctly reported,
while wounds hidden by the clothing often escaped detection. When the
external insignificance of many of the fatal wounds of the trunk is
taken into consideration this is possible; but, on the other hand, it
must be borne in mind that the head is in any attitude the most
advanced, and often the most exposed, part of the body, and even when
the soldier had taken 'cover,' it was frequently raised for purposes of
observation. For the latter reasons I believe injury to the head fully
deserved the comparative importance as a fatal accident with which it
was credited.
A number of somewhat sensational immediate recoveries from serious
wounds of the head have been placed upon record. Observation, however,
shows that these, with but few exceptions, belonged either to certain
groups of cases the relatively favourable prognosis in which is familiar
to us in civil practice, or that the wounds were received from a very
long range of fire, and hence the injuries were strictly localised in
character.
ANATOMICAL LESIONS
_Wounds of the scalp._--Nothing very special is to be recorded with
regard to these; they either formed the terminals of perforating wounds,
or were the result of superficial glancing shots. The glancing wounds
were of the nature of furrows, varying in depth from mere grazes to
wounds laying bare the bone. Their peculiarity was centred in the fact
that a definite loss of substance accompanied them, the skin being
actually carried away by the bullet; hence gaping was the rule. Every
gradation in depth was met with, but the only situations in which wounds
of considerable length could occur were the frontal region in tranverse
shots, or, when the bullet passed sagitally, the sides of the head, or
the flat area of the vertex.
The danger of overlooking injuries to the bone was of special importance
in the short subcutaneous tracks occasionally met with at the points at
which the surface of the skull makes sharp bends. In all such wounds it
was a safe rule to assume a fracture of the skull until this was
excluded by direct examination. In some of the gutter wounds and
subcutaneous tracks crossing the forehead and sides of the head, signs
of intracranial disturbance were occasionally observed in the absence of
external fracture, such as transient muscular weakness, unsteadiness in
movements, giddiness, diplopia, or loss of memory and intellectual
clearness. In connection with such symptoms the classical injury of
splintering of the internal table of the skull, the external remaining
intact, had to be borne in mind, but I observed no proven instance of
this accident. I am of opinion, moreover, that its occurrence with small
bullets travelling at a high degree of velocity must be very rare, since
little deflection is probable unless the contact has been sufficiently
decided to fracture the external table; while in the cases of spent
bullets the injury is unlikely, as requiring a considerable degree of
force.
_Injuries to the cranial bones, without evidence of gross lesion to the
brain._--It may be premised that these were of the rarest occurrence,
and they may be most readily described by shortly recounting the
conditions observed in a few cases I noted at the time. The injuries
resulted from blows with spent bullets, from bullets barely striking the
skull directly, or those striking over the region of the frontal
sinuses. Wounds of the mastoid process will not be considered in this
connection as being of a special nature (see p. 299).
I saw only one case of escape of the internal, with depressed fracture
of the external, table of the skull.
