Treatment of osteonecrosis of the femoral head with vascularized bone grafting.
Osteonecrosis of the femoral head (ONFH) is a challenging diagnosis for the patient and treating surgeon. Though its cause is poorly understood, several methods of surgical treatment exist and are performed with variable success. Vascularized bone grafting is one such treatment that attempts to restore viable bone, structural support, and blood supply to the avascular portion of the femoral head. This review summarizes the various approaches to this technique that have been proposed and put into practice. The cost effectiveness of these procedures, both in time and resources, has been evaluated and found to be favorable. The use of revascularization procedures, along with the introduction of other potentiating factors, may signal an exciting future for this debilitating disease process.
