ABSTRACT

Objective:To investigate a new method and its clinical results in the treatment of avascular necrosis of the femoral head in young adults. Method:The necrotic bone was removed and iliac periosteum and bone with vascular pedicle was transplanted in 25 cases (28 hips) ,age 12-42 years old in this group. Rehabilitation technique were applied after surgery. The time of follow up was 3-9.5 years. To evaluate the results, we used the standard score recommended by Society of Osteonecrosis in Chinese Medical Association. Result:16 cases were excellent,7 cases good, and 2 cases fair. The rate of excellent and good was 92%. Conclusion:Transplantation of iliac periosteum and bone with vascular pedicle has the effect on revascularization and new bone formation, which following with rehabilitation methods may promote the reconstruction of the necrotic femoral head and prevent it to collapse. Thus the pathogenesis process had been stopped.
