ition; generally speaking, prognosis, in such cases, is unfavorable.
Because of the leverage afforded by the extremity, immobilization of the
radius is difficult. Any sort of mechanical appliance, which will
immobilize these parts, is likely to produce pressure-necrosis of the
soft structures so contacted. There is occasioned thereby much pain and
the subject becomes restive, unmanageable and sometimes the splints are
completely deranged because of the animal's struggles, and much
additional injury to the leg is done. Occasionally, an otherwise
favorable case is thus rendered hopelessly impossible to handle, and the
subject must be destroyed several days after treatment has been
instituted.
Consequently, unless all conditions are good, and the affected animal a
favorable subject, young, of good disposition, and the fracture a simple
transverse one, complete recovery is not likely to result from any
practical means of handling.
Treatment.--Mature subjects ought to be put in slings and kept so
restrained throughout the entire time of treatment. Immobilization of
the broken parts of the bone is the object sought. This is attempted by
practitioners who employ various methods, and each method has its
advocates.
Casts are used by some and serve very well in many cases; but because of
their bulk and unyielding and rigid nature, they are not well adapted to
use on fractures of bones proximal to the carpus and tarsus. This is in
reference to plaster-of-paris casts or those of any similar material.
Appliances which depend on glue or other adhesive substances combined
with leather, wood or fiber for their support, are efficacious but not
comfortable.
The use of heavy leather when the member has been suitably padded with
cotton and bandages, constitutes a very good manner of reducing fracture
of the radius or of the tibia. Leather when cut to fit both the medial
and lateral sides of a leg, and firmly held with bandages, will form a
firm support that yields slightly to changes of position, thus making
for comfort of the subject.
Such a splint or support should extend from the fetlock region to the
elbow, but the cotton and bandages are to reach to the foot. When one
considers that, with the supportive appliance placed on each side of the
affected member, rigidity is accomplished as much from tensile strain
put upon the leather as from its own stiffness, it is seen that the
leather need not be of the heaviest--sole leath
