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 unimportant and deserving of no more attention than placing the animal in such position as to insure it against subsequent injury until the bones are united. Some distortion may result, but not sufficient to warrant interference.
