Avascular necrosis of the femoral head is a pathologic process resulting from the death of the cells in bone tissue after interruption of its blood supply by traumatic or non-traumatic causes and it results in collapse of the femoral head and early degeneration of the joint. While a number of factors have been documented to cause avascular necrosis, alcoholism, excessive steroid use, trauma, vascular compression, sickle cell anemia, caisson disease and Gaucher`s disease are the most common etiologic factors. In some cases it is idiopathic. When an area of bone is completely deprived of its blood supply, local cell death occurs, resulting in necrotic bone. Articular cartilage which is not affected by these changes primarily may become affected secondarily by mechanical pressure and necrosis develops in time causing a picture of arthritis to develop. It is difficult to treat this problem because of the lack of effective measures to interrupt the necrosis process. Different treatment modalities can be used to treat this disease depending on the stage of the disorder at the time of diagnosis.
