Avascular Necrosis (Hip)
About Avascular Necrosis (Hip)
Avascular necrosis of the hip occurs when a part of the bone dies as the result of loss of its blood supply. The lack of blood may cause the surface of the bone to collapse, and arthritis will result.
The condition can be caused by a number of things including trauma, the use of corticosteroids, excessive alcohol consumption and as a result of some diseases. Avascular necrosis can also occur if an injury to the hip, such as a dislocation or fracture, limits the blood supply to the femoral head.
Symptoms vary depending on the cause, but hip pain is common. Although nonsurgical treatment options can relieve pain and slow the progression of the disease, the most successful treatments are surgical. Patients with avascular necrosis that is caught in the very early stages are good candidates for hip preserving procedures. If it has progressed to a significant stage and the bone has collapsed, hip replacement surgery may be required.
