    Abstract:
    OBJECTIVE: To study the effect of surgical treatment with core depression and allo-fibular grafting on osteonecrosis of the femoral head in early stages. METHODS: From June 1998 to August 2004, 22 patients with necrosis of the femoral head (39 hips) were treated with core depression and allo-fibular grafting, including 17 males and 5 females. Necrosis was classified as Stages I - III according to ARCO classification system. Their ages ranged from 22 to 60 years and pain duration was 2 to 12 months preoperatively (6.5 months on average). The regular examinations of joint function, X-ray, ECT,CT and MRI were conducted before surgery and after 15 days, 3 months, and 6 months of surgery. RESULTS: All patients were followed up for 3 to 74 months (31.4 months on average). Symptoms 17 of the patients were relieved evidently. Harris hip score from 78 points preoperatively to 91.6 points. The X-ray films 18 of the patients showed that the geography of the hip joint kept intact with no deterioration. Osteogenesis was observed by regular examinations. Two cases (4 hips, 10.25%) were revised by total hip replacement, and 3 cases (4 hips, 10.25%) without THR worsened postoperatively. CONCLUSION: The method is less traumatic than common procedures. The joint function can be recovered within 2-4 weeks. Clinical symptoms are greatly improved. This method is effective at least in short term and the long-term effect needs further study.
