In addition to the bands mentioned above, which attach the lateral
cartilages to the extremities of the navicular bone, there are three
ligaments on either side which attach the cartilages to the phalanges.
An ill-defined elastic band passes from the middle part of the border of
the first phalanx to the upper part of the cartilage, detaching a branch
to the plantar cushion.
A short strong band connects the anterior extremity of the cartilage
with the rough eminence on the second phalanx in front of the attachment
of the lateral ligament of the coffin joint.
The lower border of the cartilage is covered externally by fibers which
attach it to the wing of the third phalanx.
