Vascularized Compared with Nonvascularized Fibular Grafts for Large Osteonecrotic Lesions of the Femoral Head

Abstract

Vascularized fibular grafting was associated with better clinical results and was more effective than nonvascularized fibular grafting for the prevention of collapse of the femoral head in a matched population with a Steinberg Stage-IIC or larger osteonecrotic lesion. The results of vascularized grafting were best when the procedure was used to treat precollapse lesions (Steinberg Stage IIC).
