application or even a vesicant is in order.

Where abatement of the infectious process does not take place, and
suppuration of the structures in the vicinity of the joint occurs, it is
necessary to provide drainage for pus. In some cases of strangles, for
instance, large pus cavities are formed and drainage is imperative.
However, metastatic inflammation of this joint is seldom observed except
in cases of strangles. The animal should be kept perfectly quiet until
recovery has taken place.


Injuries.

Injuries to the scapulohumeral joint may be the result of kicks, runaway
accidents or bruises from the collar, and there may result, because of
such injuries, reactionary inflammation which will vary in intensity
from the mildest synovitis to the most severe arthritis, causing more or
less lameness.

Treatment.--The general plan of treatment in this form of arthritis is
the same as has been outlined under the head of infectious arthritis,
with the exception that there is seldom occasion to provide for drainage
of pus.


Wounds.

Wounds which cause a break of the skin and fascia overlying the
scapulohumeral joint are usually of little consequence, unless the blow
is of sufficient force to directly injure the articulation, and in such
