l the seat of
the injury. If it was the result of a blow, there may be some abrasion of
the skin. The diagnosis is only important as an aid in determining the
proper course to pursue.
If paralysis is present and a depression or irregularity of the spinal
column is so apparent as to leave no doubt of the existence of a fracture,
the only alternative is to destroy the animal, for of recovery there can be
no hope. If, on the other hand, the paralysis is incomplete and there is no
depression or irregularity of the spinal column or other evidence of
fracture, the patient should be made as comfortable as possible by being
placed in a well-bedded box stall and a few days permitted to elapse before
the case is abandoned. The symptoms last described may possibly be the
result of a severe strain of the muscles of the loins, in which case an
improvement will soon be noticeable.
FRACTURES OF THE PELVIS.--The pelvis, or bony framework which gives shape
to the posterior part of the body, is liable to fracture in many ways. A
common one is by a separation of the two bones which constitute the whole
pelvis along the bottom and center line (symphysis pubis). In early life
the two bones are separate and distinct. The union between them, which is
at first cartilaginous, undergoes a change and is converted into bone, so
that in adult life the whole pelvis is practically one bone. The point on
which the two bones are united is weaker than the adjoining parts of the
bone. When an animal slips violently, spreading the legs wide apart, the
weaker materials give way and the bones are divided. If the accident is
noticed when it occurs, it is likely to throw light on the nature of the
injury. The animal will immediately go stiff behind, the legs being spread
apart. Further examination may be made by introducing the hand, previously
carefully oiled, into the rectum or vagina and pressing down along the
central line, which will cause the patient to evince acute pain. In this
case no appliance can be used to advantage. The animal should be tied in a
stall until the parts become reunited and the lameness disappears.
Fracture of the posterior parts of the bone (ischium), which forms the
point of the buttocks occasionally occurs. The buttock on the injured side
will be less prominent than the other. Careful manipulation will generally
move the parts so that crepitus may be recognized. If the fracture is
through the posterior part of the bone, it is
