Avascular necrosis of the femoral head is a fairly common condition affecting primarily men in their third to fifth decades. It has a high morbidity rate. If left untreated, the femoral head collapses and degenerative changes appear within 2-3 years. It is important to prevent progression of the disease by early management before the head collapse. AVN is one of the common causes for hip arthroplasty in the young and patients may require more than one in their life time. Many non operative treatments have been found in the literature with variable results like bisphosphonates, extracorporeal shock wave therapy, pulsed electromagnetic therapy, anticoagulants, statins, and hyperbaric oxygen etcetera.
