recovery in
humeral fracture in a foal three days old. The only treatment given was
the application of a pitch plaster from the top of the scapula to the
radius. The colt was kept in a comfortable box stall and in about four
weeks regained use of the leg. Complete recovery eventually resulted. In
the experience of the author, recovery has not occurred in humeral
fractures.

Treatment.--When animals are not aged and of sufficient value to
justify treatment, they are best supported in a sling, if halter broken.
If subjects are nervous, wild and unbroken, it is possible to employ the
sling, if care is given to train the animal to this manner of restraint.
The presence of an attendant for a day or two will reassure such
subjects so that even in these cases it may be practicable to employ the
sling.

Braces and other mechanical appliances intended to immobilize the parts
are not of practical benefit in the horse. Unlike the dog, the horse as
yet has not been successfully subjected to tolerating rigid braces for
the shoulder and hip.

Everything possible must be done that will make for the patient's
comfort. If the subject turns out to be a good self nurse, and the
nature of the fracture is such that practical apposition of the broken
ends of bone may be maintained, recovery will occur in some cases.

Inflammation of the Elbow.
(Arthritis.)

Affections of this articulation other than those which are produced by
traumatism are rare. This joint has wide articular surfaces, and
securely joined as they are by the heavy medial and lateral ligaments
(internal and external lateral ligaments), luxation is practically
impossible. When luxation does occur, irreparable injury is usually
done. Castagne as quoted by Liautard[15], reports a case of true
luxation of the elbow joint in a horse where reduction was effected and
complete recovery took place at the end of twenty-five days. This is an
unusual case. The average practitioner does not meet with such
instances.

Anatomy.--The condyles of the humerus articulate with the glenoid
cavities of the radius and a portion of the ulna. Two strong collateral
ligaments pass from the distal end of the humerus to the head of the
radius. The capsular ligament is a large, loose membrane which encloses
the articular portion of the humerus with the radius and ulna and also
the radioulnar articulation. It is attached anteriorly to the tendon of
the biceps brachii (flexor brachii). The capsul
