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
cases, the treatment of the injury along general surgical principles,
such as cleansing the area, providing drainage for wound secretion, and
the administration of suitable dressing materials such as antiseptic
dusting powder, is all that is required for the wound. The symptoms
manifested by the subject in such cases are the same as have been
discussed heretofore and merit no special consideration.

Prognosis.--Unless very serious injury be done the articular portions
of the scapula or the humerus, resulting in the destruction of the
capsular ligament, prognosis is entirely favorable.

Open Joint.--Where the capsular ligament is perforated and the
condition becomes one of open joint, then a special wound treatment
becomes necessary. The surface of the skin is first freed from all hair
and filth in the vicinity of the wound. The wound proper is cleared of
all foreign material either by clipping with the scissors, curetting or
mopping with cotton or gauze pledgets. The whole exposed wound surface
as well as the interior of the joint cavity, if much exposed, is
moistened with tincture of iodin. Subsequent treatment consists in a
local application of a desiccant dusting powder, which should be applied
five or six ti
