Symptomatology.--Bog spavin is recognized by the distended condition

of the joint capsule which is prominent just below the internal tibial

malleolus and this affection is characterized by a fluctuating swelling

which varies considerably in size in different subjects. Except in cases

of acute synovitis, lameness is not present and in chronic distension of

the capsule of the tarsal joint, no interference with the subject's

usefulness occurs. In the majority of instances, the disfigurement which

attends bog spavin is the principal objectionable feature. The condition

is bilateral in many instances, and in such cases the subjects have a

predisposition to this condition or it follows attacks of strangles or

other debilitating ailments. Because of a rapid and unusual growth,

bilateral affections are of frequent occurrence in some animals.

Treatment.--The most practical method of handling bog spavin consists

in aspiration of synovia and injection of tincture of iodin. Discretion

should be employed in selecting subjects for treatment, regardless of

the manner in which such cases are to be handled. Where there exists

chronic distension of the joint capsule of several years' standing in

old or weak subjects, needless to say, recovery is not likely to result.

When animals are vigorous and two or three months' time is available,

treatment may be begun with reasonable hope for success.

The average subject is handled standing and can be restrained with a

twitch, sideline and hood. Aspirating needles and all necessary

equipment must be in readiness (sterile and wrapped in aseptic cotton or

gauze) so that no delay will occur from this cause when the operation

has been started. The central or most prominent part of the distended

portion of the capsule is chosen for perforation and an area of an inch

and a half in diameter is shaved. The skin is cleansed and then painted

with tincture of iodin. The sterile aspirating needle is pushed through

the tissues and into the capsule with a sudden thrust. With a large and

sharp needle (fourteen gauge), synovia can be drawn from the cavity in

most instances and the subject usually offers no resistance. By

compressing the distended capsule and surrounding structures with the

fingers, considerable synovia may be evacuated. In singular instances,

no synovia is to be aspirated with the needle, and in such cases the

amount of iodin injected needs be increased, possibly twenty-five per

cent., as experience will indicate. From two to five cubic centimeters

of U.S.P. tincture of iodin is injected through the aspirating needle

into the synovial cavity of the joint, and the exterior of the parts are

vigorously massaged immediately after injection to stimulate

distribution of the iodin throughout the synovial cavity. Where a

bilateral affection exists, two or three weeks' time should intervene

between the treatments of each leg. A sterile metal syringe equipped

with a slip joint for the needle is well adapted to this operation.

Lubrication of the plunger with heavy sterile vaseline or glycerin will

prevent the syringe from being ruined by the iodin.

Following the injection, the subject is kept in a stall or in a suitable

paddock, so that conditions may be observed for four or five days. The

object sought by the introduction of iodin is not only for a local

effect upon the synovial membranes in checking secretions, but the

production of an active inflammation and great swelling, which will

remain from four weeks to three months subsequent to the injection. This

periarticular swelling should produce and maintain a constant pressure

over the entire affected parts for a sufficient length of time until

normal tone is re-established.

In some cases, swelling does not develop as the result of a single

injection of iodin. When marked swelling has not taken place within five

days, none will occur and a repetition of the injection may be made

within ten days after the first treatment has been given. One may safely

increase the amount of iodin at the second injection in such cases by

one-fourth to one-third.

In Europe this method of treating bog spavin has been employed by

Leblanc, Abadie, Dupont and others according to Cadiot; but Bouley, Rey,

Lafosse and Varrier used it with bad results. Where a perfect technic is

executed (and no other is excusable in this operation), no infection

will occur if a reasonable amount of iodin is injected. The dilution of

iodin with an equal amount of alcohol has been practised by the author

in many cases, but later this was found unnecessary.

Other methods of treatment have been used with success. Perhaps the most

heroic consists in opening the joint capsule with a bistoury or with

the actual cautery. Such practice is too hazardous for general use and

is not to be recommended, although good results should follow the

employment of such methods if infectious arthritis does not occur.

Line firing over the distended capsule is a practical method of

treatment. This is attended with good results in young animals in many

cases, but considerable blemish is caused when sufficient irritation is

produced to stimulate resolution.

Vesication also is successfully employed in some instances. However,

only cases of recent origin in young animals--colts of two years or

younger--yield to blistering, and in some affected colts no doubt

recovery would have been spontaneous had no treatment been instituted.

Ligation of the saphenous vein at two points, one above and the other

below the distended ligamentous capsule, is an old operation, which has

undoubtedly given good results in some cases, although it does not seem

to be a rational procedure.

After-Care.--After swelling has fully developed--which occurs within a

week--the subject is turned to pasture and no attention is necessary

thereafter. A gradual subsidence of the swelling occurs and in the

average instance, this completely resolves within six or eight weeks.

Complete recovery succeeds the aspiration-and-injection-treatment in

about seventy-five per cent of cases as the result of one operation, and

subjects may be gradually and carefully returned to work in about sixty

days after treatment has been given.

Distension of the Tarsal Sheath of the Deep Digital Flexor.

(Thoroughpin.)

The terms "thoroughpin" or "throughpin" are translations from the French

_vessignon chevillé_ and have the same significance. They are so named

because of the diametrically opposed distensions of the sheath of the

deep flexor tendon in such manner that the distensions appear to be due

to a supporting peg.

Anatomy.--The theca through which the deep digital flexor (perforans)

plays in the tarsal region, begins about three inches above the inner

tibial malleolus and extends about one-fourth of the way down the

metatarsus. The posterior part of the capsular ligament of the hock

joint is very thick in its most dependent portions and is in part

cartilaginous, forming a suitable groove for the passage of the deep

flexor tendon.

[Illustration: Fig. 57--Thoroughpin. Showing distension of the sheath of

the deep flexor tendon as it protrudes antero-externally to the fibular

tarsal bone (calcaneum).]

Etiology and Occurrence.--Strains and sequellae to debilitating

diseases constitute the usual causes of this affection. As a result of

acute synovitis a chronic synovial distension of the tarsal sheath

occurs. Bog spavin is often present in case of thoroughpin but the two

conditions are separate and distinct excepting in that both may occur

simultaneously and as the result of the same cause. Some animals are

undoubtedly predisposed to disease of synovial structures. The average

horse that has been subjected to hard service on pavements or hard roads

at fast work suffers synovial distension of bursae, thecae or of joint

capsules. Some of the well bred types such as the thoroughbred horses

may be subjected to years of hard service and still remain "clean

limbed" and free from all blemishes. Thus it seems that subjects of

rather faulty conformation, animals having lymphatic temperaments and

the coarse-bred types, are prone to synovial disturbances such as

thoroughpin, bog spavin, etc., sometimes having both legs affected.

[Illustration: Fig. 58--Fibrosity of tarsus as a complication in chronic

thoroughpin.]

Symptomatology.--Thoroughpin is characterized by a distended condition

of the tarsal sheath which is manifested by protrusions anterior to the

tendo Achillis. However, where but moderate distension of the sheath

exists, there is little, if any, bulging on the mesial side of the hock

and but a small hemispherical enlargement is presented on the outer side

of the tarsus, anterior to the summit of the os calcis. In some

instances the protruding parts assume large proportions, but always,

because of the relationship between the fibular tarsal bone (calcaneum)

and the tendon sheath, the larger protrusion is situated mesially.

During the acute inflammatory stage there is marked lameness present but

this soon subsides when local antiphlogistic agents are applied to the

parts. In fact, spontaneous relief from lameness usually results in the

course of ten days' time following the appearance of thoroughpin. No

lameness marks the advent of this affection when it develops as the

result of continuous strain and concussion occasioned by hard service,

and local changes tend to remain in _status quo_.

[Illustration: Fig. 59--Another view of same case as illustrated in Fig.

58.]

Treatment.--Rest and the local application of heat or cold will suffice

to promote resolution of acute inflammation and lameness when present

will subside within two weeks. In chronic affections, however, the matter

and manner of effecting a correction of the condition--distended tarsal

sheath--merit careful consideration. While drainage of distended thecae

and bursae by means of openings made with hot irons was practiced by the

Arabs, centuries ago, and good results have attended such heroic

corrective measures, nevertheless the occasional serious complications

which result from infection likely to be introduced in following such

procedures, cause the prudent and skilful practitioner to employ safer

methods of treatment.

The application of blistering agents is of no value in stimulating

resorption of an excessive amount of synovia in chronic cases and the

actual cautery when employed without perforation of the synovial

structure, is of little benefit. Trusses or mechanical appliances for

the purpose of maintaining pressure upon the distended parts are of no

practical value because of the great difficulty of keeping such

contrivances in position. They usually cause so much discomfort to the

subject that they are not tolerated.

A very practical and fairly successful method of treatment consists in

the aspiration of a quantity of synovia and injecting tincture of iodin.

Cadiot recommends the drainage of synovia with a suitable trocar and

cannula and injecting a mixture consisting of tincture of iodin, one

part, to two parts of sterile water, to which is added a small quantity

of potassium iodid. The latter agent is added to prevent precipitation

of the iodin. This authority (Cadiot) further advocates the removal of

practically all of the synovia that will run out through the cannula and

the immediate introduction of as much as one hundred cubic centimeters

of the above mentioned iodin solution. This solution is allowed to

remain in the synovial cavity a few minutes and by compressing the

tissues surrounding the tendon sheath, the evacuation of as much of the

contents of the synovial cavity as is practicable, is effected.

Subsequently the subject is allowed absolute rest and more or less

inflammatory reaction follows. In some cases there occur marked lameness

and some febrile disturbance, but where a good technic is carried out,

no bad results follow. At the end of four weeks' time, horses so treated

may be returned to service, but the full beneficial effect of such

treatment is not experienced until several months' time have elapsed.

Where good facilities for executing a careful technic in every detail

are at hand, incision of the tarsal sheath, evacuation of its contents

and uniting its walls again by means of sutures and providing for

drainage with a suitable drainage tube, may be practiced. This manner of

treatment has been satisfactory in the hands of a number of surgeons.

Capped Hock.

Enlargements which occur upon the summit of the os calcis, whether

hypertrophy of the skin and subcuticular fascia, the result of injury or

repeated vesication, distension of the subcutaneous bursa or injury to

the superficial flexor tendon (perforatus) or its sheath, are generally

known as capped hock. However, the term should be restricted to use in

reference to distensions of synovial structures of that region.

Etiology and Occurrence.--Usually there occurs a hygromatous

involvement of the subcutaneous bursa due to contusion. As in bog

spavin, following certain infectious diseases (influenza, purpura

hemorrhagica, etc.) there remains a distended condition of the

subcutaneous bursa, after swelling of the member has subsided. In

feeding pens where numbers of young mules are kept in crowded quarters

many cases may be observed. In some instances where violent contusions

result from kicking cross-bars of wagon shafts (by nymphomaniacs or in

habitual kickers where there is opportunity for doing such injury) the

superficial flexor tendon and its synovial apparatus are injured and a

more serious condition may result.

Symptomatology.--In acute and extensive inflammation of the parts,

lameness is present, but in the average case no inconvenience to the

subject results. The prominent site of the affection is cause for an

unsightly blemish. This is undesirable, particularly in light-harness or

saddle horses. These affections are characterized by a fluctuating mass

which has a thin wall and in all cases of long standing the condition is

painless.

By careful palpation one may readily distinguish between a hygromatous

condition of the superficial bursa and involvement of the underlying

structures. Affection of the expanded portion of the flexor tendon and

contiguous structures makes for an organized mass of tissue which is

somewhat dense and in some instances painful to the subject when

manipulated. This is particularly noticeable in cases where the parts

are regularly and repeatedly injured as in habitual kickers.

[Illustration: Fig. 60--"Capped hock." Distension of the bursa over the

summit of the os calcis.]

Treatment.--In acute inflammation, antiphlogistic applications are

indicated and the subject must be kept quiet. The matter of bandaging

the hock is a difficult problem in some cases and needs be done with

care. As has been previously stated in this volume, the tarsus needs to

be well padded with cotton before the bandages are applied and only a

moderate degree of tension is employed in applying the bandages lest

anemic-necrosis result from pressure. In distension of the superficial

bursa, after clipping the hair over a liberal area and preparing the

skin by thoroughly cleansing and painting with tincture of iodin, the

capsule is incised with a bistoury. An incision about an inch in length,

situated low enough to provide drainage, is made through the tissues and

the contents are evacuated. Tincture of iodin is injected into the

cavity and the parts are covered with cotton and bandaged. No after-care

is necessary except to retain the dressing in position, which is not

difficult in the average case if the subject is kept tied. If much

resistance is exhibited, such as extreme flexion of the bandaged hock,

the animal may be put in a sling and little if any objection to the

bandage will be offered thereafter. The wound may be dressed at the end

of forty-eight hours and no redressing will be necessary in the average

instance if infection is not present. But slight local disturbance and

little distress to the subject result in cases so treated even when

infection occurs, but a good technic is possible of execution in most

instances and no infection should take place.

The surgical wound heals in two or three weeks and inflammation

gradually subsides. Bandages are retained one or two weeks, as the case

may require, and subsequently a good wound lotion may be employed

several times daily. A good lotion for such cases as well as in many

others has long been employed with success by Dr. A. Trickett of Kansas

City. It consists of approximately equal parts of glycerin, alcohol and

distilled extract of witch hazel, to which is added liquor cresolis

compositus, two percent, and coloring matter q.s.

Complete resolution does not occur in the average case. There remains

some hyperplastic tissue and even where the enlargement is slight, the

prominent situation of the affection precludes its being unnoticed.

In disease of the flexor tendon and its bursa where contiguous

inflammation of tissue is present, the parts are blistered or fired.

Line firing is beneficial in such instances but in all cases the cause

is to be removed if possible.

Rupture and Division of the Long Digital Extensor

(Extensor Pedis).

Etiology and Occurrence.--Because of the fact that the long digital

extensor is the only extensor of the phalanges of the pelvic limb, its

rupture or division constitutes a troublesome condition, which in some

cases does not readily respond to treatment.

Rupture of this tendon may occur during work on rough and uneven roads,

particularly in range horses that are ridden over ground that is

burrowed by gophers or prairie dogs; in such cases, horses are apt to

suddenly and violently turn the foot in position of volar flexion,

thereby causing undue strain to the digital extensor and its rupture

sometimes follows. In foals of one or two days of age, this tendon is

sometimes found parted or ruptured and the condition may be bilateral.

As the result of accidents, the digital extensor may be divided and when

the wound becomes contaminated, as it does because of the marked volar

flexion (knuckling) which occurs during the course of this affection,

regeneration of tissue is checked and recovery is tardy.

Symptomatology.--There is no interference with ability to sustain

weight in such cases, when the foot is placed in normal position; but

immediately upon attempting to walk, the toe is dragged, and if weight

is borne with the affected member, it comes upon the anterior face of

the fetlock. The flexors are not antagonized and if there be an open

wound the parts soon become contaminated; or, in rupture, if animals

travel about very much, there soon occurs necrosis of the tissues of the

anterior fetlock region and the condition is rendered incurable. Cases

are reported of animals that have suffered rupture of the long digital

extensor and the subjects learned to throw the member forward during

extension, substituting for the extensor tendon the pendulum-like

momentum which the foot affords when so employed; and a walking and even

a trotting pace was possible without doing injury to the fetlock region.

Where a subcutaneous division exists as in rupture, the divided ends of

the tendon may be definitely recognized by palpation.

Treatment.--Subjects are best put in slings and kept so confined until

regeneration of tendinous structures has been completed. This requires

from six weeks to two months' time. In addition, the extremity is kept

in a state of extension by means of suitable splints and shoes,--a shoe

equipped with an extension at the toe and perforated so that a steel

brace may be hooked into the perforation and the brace fashioned to be

buckled to the upper metatarsal region. When braces are placed in front

of the foot, great care is necessary in properly padding the member with

cotton lest sloughing from pressure occurs at the coronet; but this does

not apply in rupture of extensors so much as where flexors are ruptured.

Open wounds are treated along general surgical lines, dressed as

frequently as occasion demands, and recovery will be complete in a few

months' time unless much of the tendon has been destroyed. In one

instance, the author had occasion to observe such a condition, which,

because of the extensive destruction of tendon and lack of facilities

for giving proper attention to the subject, results were so unfavorable

that it was deemed necessary to destroy the animal.

Wounds From Interfering.

When, during locomotion, injury is inflicted upon the mesial side of an

extremity by the swinging foot of the other member, the condition is

termed interfering.

Etiology and Occurrence.--Faulty conformation, bad shoeing and

over-work are the principal causes of interfering. Horses that are "base

narrow" or that have crooked legs are quite apt to interfere. Shoes that

are put on a foot that is not level or applied in a twisted position, or

shoes wide at the heel will often cause interfering and injury. Animals

that are driven at fast work until they become nearly exhausted may be

expected to interfere. Such cases are frequently observed in young

horses that are driven over rough roads, particularly when so nearly

exhausted or weakened from disease or inanition that the feet are

dragged forward rather than picked up and advanced in the normal manner.

Symptomatology.--Wounds inflicted by striking the extremities in this

manner present various appearances and occasion dissimilar

manifestations. The hind legs are almost as frequently affected as the

front and the fetlock region is most often injured, though wounds may be

inflicted to the coronet. In front, the carpus is sometimes the site of

injury.

When only an abrasion is caused, little if any lameness occurs, but

where interfering is continued and nerves are involved or subfascial

infection and extensive inflammation succeed such abrasions, marked

lameness and evidence of great pain are manifested. Frequently, in

chronic cases affecting the hind leg, the fetlock assumes large

proportions, and at times during the course of every drive the subject

strikes the inflamed part, immediately flexing and abducting the injured

member, and the victim hops on the other leg until pain has somewhat

subsided.

Interfering is much more serious in animals that are used at fast work

than in draft horses. In light-harness or saddle horses, it may render

the subject practically valueless or unserviceable if the condition

cannot be corrected.

Treatment.--Wherever possible, cause is to be removed and if animals

are properly used, ordinary interfering wounds will yield to treatment.

If the shoeing is faulty, this should be corrected, the foot properly

prepared and leveled before being shod and suitable shoes applied. In

young animals that become "leg-weary" from constant overwork, rest and

recuperation are necessary to enhance recovery. In such cases it will be

found that very light shoes, frequently reset, will tend to prevent

injury to the fetlock region such as characterizes these injuries of

hind legs.

Palliative measures of various kinds are employed where cause is not to

be removed and a degree of success attends such effort. In draft horses

or animals that are used at a slow pace, shields of various kinds are

strapped to the extremity and protection is thus afforded. Or, large

encircling pads of leather, variously constructed, serve to cause the

subject to walk with the extremities apart.

Interfering shoes of different types are of material benefit in many

instances. Often the principle upon which corrective shoeing is based is

that the mesial (inner) side of the foot is too low; the foot is

consequently leveled and the inner branch of the shoe is made thicker

than the outer, altering the position of the foot in this way. This is

productive of desirable results. However, much depends upon the manner

in which the foot in motion strikes the weight-bearing member as to the

corrective measures that are indicated. This belongs to the domain of

pathological shoeing and the reader is referred to works on this subject

for further study of this phase of lameness.

Lymphangitis.

Excluding glanders, in the majority of instances, lymphangitis in the

horse, such as frequently affects the hind legs, is due to the local

introduction of infectious material into the tissues as a result of

wounds. However, one may observe in some instances an acute lymphangitis

which affects the pelvic limbs of horses and no evidence of infection

exists. Consequently, lymphangitis may be considered as _infectious_ and

_non-infectious_.

INFECTIOUS LYMPHANGITIS.

Etiology and Occurrence.--Traumatisms of the legs frequently result in

infection and when such injuries are near lymph glands, even though the

degree of infection be slight, more or less disturbance of function of

the muscles in the vicinity of such glands occurs and lameness follows.

The prescapular, axillary and cubital lymph glands when in a state of

inflammation, cause lameness of the front leg, and the superficial

inguinal and deep inguinal lymph glands not infrequently become involved

also. Because of the location of these lymph glands, they are subject to

comparatively frequent injury and inflammation, causing lameness more

often than other lymph-gland-affections.

Small puncture wounds in the region of the elbow are often met with.

These may be inflicted when horses lie down upon sharp stumps of

vegetation or shoe-calk injuries may be the means of introducing

contagium, and an infectious inflammation results. Abscess formation,

the result of strangles or other infection in the prescapular glands,

may be observed at times. Following castration, the inguinal lymph

glands may become involved in an infectious inflammation and locomotion

is impeded to a marked degree. Horses running at pasture sometimes

become injured by trampling upon pieces of wood, causing one end of

these or of various implements to become embedded in the soft earth and

the other end to enter at the inguinal region and even penetrate the

tissues to and through the skin and fascia just below the perineal

region.

Nail punctures resulting in infection frequently cause an infectious

lymphangitis and a marked and painful swelling of the legs supervenes.

[Illustration: Fig. 61--Chronic lymphangitis. Showing hypertrophy of the

left hind leg, due to repeated inflammation.]

Symptomatology.--Lameness, mixed or swinging-leg, signalizes the

presence of acute lymphangitis. There is always more or less swelling

present and manipulation of the affected parts gives pain to the

subject. Depending upon the character of the infection and its extent,

there is presented a varying degree of constitutional disturbance. There

may be a rise in temperature of from two to five degrees, and in such

instances there is an accelerated pulse. Where much intoxication is

present, anorexia and dipsosis are to be noticed.

Swelling may increase gradually and in time discharge of pus may take

place spontaneously without drainage being provided for, if the

character of the infection does not cause early death. In these cases

lameness is pronounced and the cause of the disturbance is to be sought,

particularly if the condition be due to a nail puncture.

[Illustration: Fig. 62--Elephantiasis.]

Treatment.--Location of the site of injury is advisable in all cases

and in some instances provision for drainage, as in puncture wounds, is

helpful. Locally, curettage and the application of suitable antiseptics

are indicated. Hot fomentations are beneficial and should be continued

for several days if necessary, to stimulate resolution. A brisk purge

should be admintered at the onset and strychnin, because of its indirect

stimulative effect upon the circulation together with its tonic effect

upon the musculature, is beneficial.

In all such cases rational treatment, good hygiene and careful nursing

are the principal factors which stimulate recovery. Individual

resistance or lowered vitality has a marked influence on the course of

this affection.

NON-INFECTIOUS LYMPHANGITIS.

This type of lymphangitis is associated with, or the result of, a

derangement of digestion. It affects heavy draft horses, rarely other

types of animals, and involves one or both hind legs.

Occurrence.--In healthy and well nourished horses irregularly used,

this affection may suddenly manifest itself. It occurs in singular

instances in mares that are in advanced pregnancy even when such animals

are at pasture. Usually, however, this malady is found in heavy draft

horses that have been kept stabled from one to three days.

Symptomatology.--At the outset in severe cases, there is elevation of

temperature, labored breathing, accelerated pulse, anorexia and more or

less swelling of the affected members. Swelling is very painful and when

the affected legs are palpated, pain is manifested by flinching. The

inguinal lymph glands are often swollen but in some cases they are not

affected in any perceptible degree. In the average case suppuration does

not occur and when conditions are favorable, resolution is complete

within ten days. The extent of the involvement and the intensity of the

affection vary materially in different cases and a chronic lymphangitis

may succeed the acute attacks and finally in some instances,

elephantiasis results.

Treatment.--An active purgative should be given at once and in the

ordinary case, stimulants are indicated. If marked distress is present,

morphin is given and where there is much rise of temperature, cold

drinking water is offered in abundance and catharsis is enhanced by

enemata. Locally, hot applications are of benefit. Hot towels or cotton

held in position by bandages and kept soaked with warm water will

relieve pain and stimulate resolution. Diuretics may be of benefit and

anodyne applications are to be employed with profit in some cases.

Walking exercise, if not indulged in to excess, is helpful as soon as

acute inflammation has subsided. By giving careful attention to the

regimen and providing regular exercise for susceptible subjects, this

type of lymphangitis is often forestalled.
