ding the limb perfectly quiet in a natural position, which may be done
by the application of long, wooden splints retained by bandages, or a
plaster-of-Paris bandage.
FRACTURES BELOW THE KNEE.--Fracture of the long bone below the knee
(metacarpus) and hock (metatarsus) is more common. In young animals of
quiet temperament the treatment of simple fractures here is likely to be
attended with good results. On the other hand, a compound fracture in this
region becomes a serious matter. The structures which surround the bones
are so thin that a very small degree of sloughing will expose parts of the
bones and be liable to lead to serious complications and probably fatal
results.
FRACTURES OF BONES BELOW THE FETLOCK.--These fractures are comparatively
unimportant unless associated with other serious injury. The parts can
generally be held in position without much difficulty, and union generally
takes place quite rapidly.
APPLIANCES.--Of the appliances used in the treatment of the fracture of
limbs above the knee, splints made of wood or iron strips and bandages are
likely to serve best. Below the knee plaster-of-Paris bandages are
preferable. The writer is well aware that many of the standard authors
deprecate the use of the latter, but an extensive experience leads me to
believe that they have many advantages over any of the other appliances
when used alone, and in many ways they may be used with advantage in
combination with others.
DISLOCATIONS.
Luxation, or displacement without fracture of the bones forming a joint, is
comparatively rare among cattle. It most frequently occurs in the stifle
joint, where dislocation of the kneepan (patella) takes place. A glance at
the skeleton (Pl. XXV) will show the relations better than they can be
described. It will be observed that the small, irregularly shaped bone
(patella) plays on the anterior rounded part of the lower edge of the thigh
bone (femur) and between it and the upper end of the shank bone (tibia).
The outer ridge on the lower end of the thigh bone is less prominent than
the inner one, so that displacement, when it does take place, is by
slipping outward. Such an accident may occur from direct injury or external
force, as a blow, or from slipping. When it does occur the symptoms
produced are somewhat alarming. The animal is unable to draw the leg
forward, and either stands with it thrown back with the toe pointing
downward, or, if it should succeed in getting
