an excessive degree
of lameness, and in some instances a dropping back of the fetlock, with
perhaps a straightened or upright condition of the pastern.
The difficulty of reduction and coaptation in this accident, and the
probability of bony deposits, as of ringbones, resulting in lameness,
are circumstances which tend to discourage a favorable prognosis.
The treatment is that which has been recommended for all fractures, so
far as it can be applied. The iron splint which has been mentioned gives
excellent results in many instances, but if the fracture is incomplete
and without displacement, a form of treatment less energetic and severe
should be attempted. One case is within our knowledge in which the owner
lost his horse by his refusal to subject the animal to treatment, the
post-mortem revealing only a simple fracture with very slight
displacement.
FRACTURES OF THE SECOND PHALANX (CORONET).
Though these are generally of the comminuted kind, there are often
conditions associated with them which justify the surgeon in attempting
their treatment. Though crepitation is not always easy to detect, the
excessive lameness, the soreness on pressure, the inability to carry
weight, the difficulty experienced in raising the foot, all these
suggest, as the solution of the question of diagnosis, the fracture of
the coronet, with the accompanying realization of the fact that there is
yet, by reason of the situation of the member, immobilized as it is by
its structure and its surroundings, room left for a not unfavorable
prognosis. Only a slight manipulation will be needed in the treatment of
this lesion. To render the immobility of the region more fixed, to
support the bones in their position by bandaging, and to establish
forced immobility of the entire body with the slings is usually all that
is required. Ringbone, being a common sequela of the reparative process,
must receive due attention subsequently. One of the severest
complications liable to be encountered is an immobile joint
(anchylosis). Neurectomy of the median nerve may relieve lameness after
a fracture of the phalanges.
FRACTURES OF THE THIRD PHALANX (OS PEDIS).
These lesions may result from a penetrating street nail, or follow
plantar or median neurectomy. In the latter instance it is caused by the
animal setting the foot down carelessly and too violently, and partly
due to degeneration of bone tissue which follows nerving.
Though these fractures a
