se suffering from a
transverse fracture of the ulna, is similar to that in radial paralysis.
Crepitation may be detected by manipulating the parts, and in some
instances of fracture of the olecranon, there occurs marked displacement
of the broken portions of the bone. Lameness is intense and the parts
are swollen and supersensitive. The capsular ligament of the elbow joint
is usually involved in the injury because fracture of the ulna may
directly extend within the capsular ligament. In such cases, there is
synovitis, and later arthritis causes a fatal termination.

Treatment.--The impossibility of applying a bandage in any way to
practically immobilize these parts in fracture of the ulna, prevents our
employing bandages and splints. Therefore, one can do little else than
to put the patient in a sling and try to keep it quiet and as nearly
comfortable as circumstances allow.

Fracture of the Radius.

Etiology and Occurrence.--From heavy blows received such as kicks,
collision with trees or in falls in runaway accidents, the radius is
occasionally fractured. In very young foals, fracture of the radius, as
well as of the tibia and other bones, results from their being trampled
upon by the mother.

Symptomatology.--Excepting in some cases of radial fracture of foals
where considerable swelling has taken place, there is no difficulty in
readily recognizing this condition. The heavy brachial fascia materially
contributes to the support of the radius, and in cases where swelling
is marked, crepitation may not be readily detected. In fact, a
sub-periosteal fracture may exist for several days or a week or more and
then, with subsequent fracture of the periosteum, crepitation and
abnormal mobility of the member are to be recognized. In such cases, the
subject will bear some weight upon the affected member, but this causes
much distress. In one instance the author observed a transverse fracture
of the lower third of the radius which was not positively diagnosed
until about ten days after injury was inflicted. In this case, without
doubt, the subject originally suffered a sub-periosteal fracture of the
bone and because the animal was a good self nurse, the brachial fascia
supported the radius until the periosteum gave way and the leg dangled.
In this instance infection took place and suppuration resulted. It was
deemed advisable to destroy this animal.

Prognosis.--In adult animals, radial fracture constitutes a grave
