Objective To evaluate the effect of the treatment of necrosis of femoral head with the free vascularized fibula grafting. Methods From October 2000 to February 2002, 31 hips in 26 patients with ischemic necrosis of the femoral head were treated with free vascularized fibula graft. Among these patients, 21 patients (25 hips) were followed up for 6-18 months(12 months on average). According to Steinberg stage:Ⅱ period, 5 hips;Ⅲ period,8 hips; Ⅳ period, 12 hips.Results Among 25hips, their Harris Hip Score at all satges were improved during the follow-up. The symptom of pain diminished or disappeared after operation. The patient’s ability to work and live was notlimited or only slightly limited during the follow-up. Radiographic evaluation showed that most femoral heads improved (18 hips) or unchanged (6 hips) and only oneworsened.Conclusion The free vascularized fibular grafting is a valuable method for femoral head necrosis. With this method, we can prevent or delay the process of the disease.
