Abstract:
Objective To evaluate the short term results of repairing osteonecrosis of the femoral head by modified free vascularized fibular grafting through Smith-Peterson approach without cutting the rectus femoris.Methods Between January,2009 and September,2012,14 osteonecrotic hips of 14 patients who underwent free vascularized fibular grafting were retrospectively studied including 10 male and 4 female.The follow up period was 24 months.The preoperative and postoperative symptoms relief,recovery of hip function (Harris score),radiographic assessment (X-ray).Results All patients got postoperative ipsilateral hip pain relief.Average Harris hip score improved significantly (68.47 ± 5.33,86.80 ± 4.72 points in preoperation and postoperation,respectively; paired t test,t =18.724,P ＜ 0.01).Postoperative X-ray results showed there were no progresses of osteonecrosis and no collapse in the operative side within 2 years follow-up.Conclusion The short term treatment results of femoral head avascular necrosis were satisfactory by using free vascularized fibular graft through Smith-Peterson approach without cutting off the rectus femoris and it may be a relatively practical option of surgical approach.
