The triceps group because of its convenient location, constitutes the
site for hypodermic injection of drugs and biologic agents, with some
practitioners; and as a result, more or less inflammation may occur. The
author has observed and treated some twenty cases where an intensely
painful infectious inflammation of the triceps brachii was caused by
the intramuscular injection of a caustic solution by a cruel and
unscrupulous empiric, whose object was to increase his practice.

Symptomatology.--As the triceps brachii is not particularly taxed
during weight bearing in the subject at rest, there may be no unnatural
position assumed during inflammation of the triceps. More or less
swelling and supersensitiveness is always present, however, and great
care and discrimination must be exercised in digital manipulation of the
triceps region because many animals are normally sensitive to palpation
of these parts. It is sometimes difficult to correctly interpret the
true state of conditions because of this peculiarity.

There is always swinging-leg-lameness, which is accentuated when the
subject is urged to trot. Where symptoms are pronounced, it is
unnecessary to cause the subject to move at a faster pace than at a walk
to recognize the condition. The forward stride is shortened and in
extremley painful conditions, no attempt is made to extend the leg. It
is simply carried _en une piéce_--flexion of the shoulder and elbow
joints is carefully avoided.

Treatment.--During the early stage of inflammation, hot or cold
applications are beneficial. Long continued use of moist
heat--fomentations--allays pain and stimulates resolution. Keeping in
contact with the painfully swollen parts a suitable bag filled with
