perforans

Of the flexor tendons, the perforans is the one commonly attacked, by reason, of course, of its more superficial position.

The flexor perforans tendon showed inflammatory softening, and was very nearly ruptured through at the level of the navicular bone.

The metacarpo-phalangeal sheath and the ring of the perforatus laid open posteriorly, and the cut edges reflected; the flexor perforans cut through at about the region of the sesamoids, and its inferior portion deflected.

Seeing that with every movement of the foot the perforans tendon is called upon to glide over this surface, it is clear that a secondary effect must be that of inducing erosion and destruction of the tendon.

We must admit, however, that the cure of the lesion is generally at the expense of slight lameness, due, in all probability, to inflammatory tissue adhesions between the flexor perforans and the perforatus, and to a partial destruction of the synovial membrane of the sheath.

-- In common with the perforans, this muscle arises from the inner condyloid ridge of the humerus.

In the articulation with which we are dealing, however, these last two symptoms are not easily detected, for the surrounding structures -- namely, the lateral and other ligaments of the joint, the extensor pedis tendon in front, and the perforans behind, together with the dense and comparatively unyielding nature of the skin of the parts -- are such as to prevent distension and fluctuation becoming marked to a visible extent.

The flexors were apparently all right, and the bending back seemed to be due to contraction of the ligaments of the joint and the sheath of the perforans.

In this manner the pressure of the perforans tendon upon the bursa is greatly increased, and the animal is caused to show symptoms of distress.
