Vascularized iliac bone grafting for avascular necrosis of the femoral head

Objective To evaluate the indications for vascularized iliac bone grafting in the treatment of osteonecrosis of the femoral head and operative results. Methods From October 1993 to August 2000, Twenty-six hips of 18 patients with osteonecrosis of the femoral head underwent vascularized iliac bone grafting. Clinical evaluation was made according to Harris Hip Score and ARCO staging system. Results Twenty-three hips of 16 patients were followed up for 31. 5 months (6-74 months) on average. The mean Harris hip score was 76peints (mean 61.7). Thirteen hips (medial 8 hips,central3 hips,lateral 2 hips). were graded 】80 points by Harriship score were. The incidence of radiographic collapse 20% was (medial),40% (central) and 75% (lateral) respectively. Conclusion Vascularized iliac bone grafting is effective for the treatment of osteonecrosis of the femoral head in short and middle term. We recommend this procedure for the patients with ONFH in ARCO stage Ⅰ , stage Ⅱ A, Ⅱ B medial and central, and stage Ⅱ
