s to destroy articular cartilage beyond repair. In
the average instance, because of arthritis which persists for a
considerable length of time, more or less ankylosis results. At best,
one can only hope for partial recovery, that is to say, the member may
regain its usefulness as a weight-supporting part, but because of
restricted or abolished joint function, locomotion is more or less
difficult. Exostoses, articular and periarticular, occur and the carpus
usually becomes a large immobile articulation. There is danger of
infection resulting in simple carpal fractures and, needless to say, in
a compound-comminuted fracture of the carpus, infection usually occurs
and a fatal outcome is probable.

When treatment is instituted, antiseptic precautions are taken in
handling the compound fractures, and in any case immobilization of the
parts is sought. Here, as has been previously pointed out, it is best to
employ leather splints, so that a maximum degree of rigidity with a
minimum of distress and inconvenience to the patient will result. The
leg must be bandaged from the hoof upward, making use of a sufficient
amount of cotton to ensure against pressure-necrosis. The leather
splints are placed mesially and laterally and, of course, need to extend
as high as the proximal end of the radius. Subjects must be kept in
slings until union of bones has become established, and as a rule there
will then exist marked ankylosis.

There is no particular difference in the handling of carpal luxation and
dislocation of other bones. Where ligaments have not been destroyed to
the extent that reduction is of no practical use, the parts are kept
immobilized, if thought necessary. Later, vesication of the whole
pericarpal region is done and the subject allowed exercise at will.

Carpitis.

Etiology and Occurrence.--Inflammation of the carpus is caused by
contusions, such as are occasioned in falling, by kicks by striking the
carpus against objects in jumping and sometimes by striking it against
the manger in pawing. The condition is of rather frequent occurrence.

Symptomatology.--Evident symptoms of inflammation in carpitis are
always present--hyperthermia, supersensitiveness and swelling. Also,
there exists lameness which is characterized by an apparent inability to
flex the leg, and there is circumduction of the leg as it is advanced
because in this way little if any flexion of the carpus (which increases
pain) is necessary.
