The article reports that the diagnosis of avaseular necrosis of the femoral head cannot be established until a relatively long time after the accident. It cannot be demonstrated roentgenographically until revascularization has commenced and resorption and new formation of bone have occurred, i.e., when the structure of the bone has become irregular or the femoral head is deformed. Dense parts represent areas with broad bone trabeculae, consisting of newly formed bone apposited on the old bony framework. The nonreorganized dead caput, for example at nonunion of the fracture, retains its original roentgenologic structure and the necrotic state of the bone escapes the radiologist.
