Abstract:
OBJECTIVETo evaluate the clinical results of continuing skeletal traction and impaction granular bone grafting via window in femoral neck for the treatment of avascular necrosis of femoral head.
METHODSFrom August 2000 to October 2004, 23 patients (35 hips) with femoral head necrosis were treated by continuing skeletal traction and impacting granular bone grafting via bone window on femoral neck. There were 18 males, 5 females, with an average age of 32 years ranging from 19 to 52 years, which included 7 hips of stage II, 28 hips of stage III. All patients had various degrees of hip joint pain and suffered from limited hip motion. The necrotic bone, granulation tissue and hardening zone were completely cleaned via bone window on the femoral neck. The autogenous granular iliac bone was grafted, and impacted persistently. Skeletal traction through femur condyles was applied continually after the operations. The effects before and after operation were compared by the hip pain, function, joint activity and X-ray.
RESULTSRegular follow-up was carried out after the patients were dismissed from the hospital. The follow-up period was 6 months, 1 year, 2 years, 3 years, 4 years, 5 years respectively. According to Wang's standard, the average score was increased from (52.66 +/- 12.53) preoperatively to (88.94 +/- 5.84) preoperatively at half a year, (89.78 +/- 6.18) at 1 year, (86.37 +/- 7.46) at 2 years, (84.08 +/- 7.57) at 3 years, (83.76 +/- 8.08) at 4 years, and (76.83 +/- 8.98) at 5 years. Scores of operation were greatly increased and the difference had statistical significance.
CONCLUSIONContinuing skeletal traction after the operation, completely cleaning the necrotic bone and impacting granular bone grafting via window on femoral neck can greatly raise the satisfactory rate of clinical effect and delay the progression of disease for avascular necrosis of femoral head.
