recognition of rupture
of either of these structures is easily recognized. When one considers
that in rupture, a position directly opposite to that which is seen in
contraction in either one of these structures, is assumed, a detailed
description of each separate condition is needless repetition.

However, it is pertinent to suggest that rupture of the deep flexor
tendon (perforans) allows a turning up of the toe. Whether it be torn
loose from its point of attachment or ruptured at some point proximal
thereto, the position is the same--heel flat on the ground, toe slightly
raised and this raising of the toe varies in degree as the subject moves
about.

When the superficial flexor (perforatus) is ruptured there is no change
in the position of the foot but the fetlock joint is slightly lowered.
The pathognomonic symptom is the lax tendon during weight bearing, which
may be felt by palpation of the tendon along its course in the
metacarpal region.

With complete rupture of the suspensory ligament there occurs a marked
dropping of the fetlock joint and an abnormal amount of weight is then
thrown upon the superficial flexor tendon (perforatus), causing it to be
markedly tensed. This is readily recognized by palpation. By palpating
the suspensory ligament from its proximal portion down to and beyond its
bifurcation, while the affected member is supporting weight, it is
possible to diagnose rupture of one of its branches.

Prognosis and Treatment.--In rupture of the superficial flexor tendon
(perforatus) because of its comparatively less important function,
prognosis is favorable and recovery takes place when proper treatment is
put into practice.

With rupture of the deep flexor tendon (perforans), especially when it
occurs at or near its point of insertion and sometimes following
disease, prognosis is unfavorable.

Rupture of the suspensory ligament constitutes a condition which is, as
a rule, hopeless, because of the impracticability of treating such
cases.

The salient feature which characterizes any practical attempt at
treatment of ruptured tendons or other portions of the inhibitory
apparatus of the fetlock region, is to retain the phalanges in their
normal position for a sufficient length of time that the approximated
ends of ruptured tendons or ligaments may unite. The length of time
required for this to occur, together with the difficulties encountered
in confining the affected extremities in suitable braces
