maller onesmay be taken to discover the nature of the injury. The iliac bones may be fractured, when it is sometimes difficult to showthe seat of the lesion. When the sacrum is damaged, there may be a fractureat the sacro-iliac synchondrosis, and the body of the sacrum may also beinvolved in these injuries. The pelvis is often damaged when the violence isof a crushing type, or it may be broken by direct violence. The ischiummay also participate in the injury. The coccyx is frequently fractured. In all doubtful cases both sides of the pelvis should be examined, andthe hip-joints should also receive attention. The common injuries are easilydistinguished, but there are many grades of fracture, where the injury maynot be demonstrable if only one radiograph be taken. Injuries near the Hip-joint In some cases of injury at the hip-joint a widening of the interarticularspace may indicate an effusion of blood into the joint, which later on maylead to inflammatory changes and abscess formation.

Q 2 ^is FRACTURES OF THE FEMUR 165 An uncommon injury to the hip-joint has been recorded, where the headof the bone was driven through the acetabulum into the pelvic cavity. Orthe acetabulum may be fractured to a lesser degree. This may be shownon examination. The Neck of the Femur is frequently broken when, especially in oldpeople, there may be impaction. Traumatic coxa vara is a fairly commonoccurrence. Fracture through the Great Trochanter is also common. It maybe localised to the trochanter or may extend downwards obliquely into theshaft. Fractures of the Femur Fracture through the Shaft below the lesser trochanter is an injuryoften met with. Fractures of the Lower End. — (1) Transverse supra - condyloidfracture is practically identical withthat involving the lower third of thefemur. (2) T- or Y-shaped fracture of thecondyles. In this a transverse frac-ture is complicated by a fissurewhich runs into the joint, separatingthe two condyles. (3) Separatio?i of either condylealways r
