手术治疗股骨头缺血性坏死202例（242髋）临床分析

目的探讨如何根据不同年龄和分期为股骨头缺血性坏死患者选择最合适的外科治疗方法。方法股骨头缺血性坏死患者共202例（242髋），其中男143例（175髋），女59例（67髋），年龄4—81（35．3±18．8）岁；根据不同年龄和分期采用不同手术方法。采用Stulberg分类标准、Harris评分标准、VAS评分法进行评价。结果202例（242髋）得到随访，术后随访1-10（6．3±1．3）年。儿童组、青年组、老年组综合优良率分别为87．2％、88．7％、85．7％；6岁及以下早中期优良率（CatterallⅡ—Ⅲ）优于大龄晚期（Catterall Ⅳ）（P〈0．05），40岁以下早中期优良率（Ficat Ⅱ-Ⅲ）优于大龄晚期（Ficat Ⅳ）（P〈0．05）；老年组组间差异无统计学意义（P〉0．05）；青年组和老年组术后Harris评分明显提高（P〈0．05）、VAS显著降低（P〈0．05）。结论儿童特别是6岁及以下早中期患儿最适合用带血管蒂大转子或髂骨骨膜瓣移位术；中青年特别是40岁以下早中期患者最适合用带血管蒂大转予或髂骨骨瓣移位术，对于〉50岁或〈50岁晚期患者适合行混合型或非骨水泥型THA（Total hip arthroplasty）。

Operative treatment for osteonecrosis of the femoral head: a review of 202cases

Objective To find out the optimal operative methods for the patients with osteonecrosis of the femoral head according to age and the staging. Methods The current study assessed 202 patients(242 hips)from 1998 to 2008 with an average follow-up of 6.3years (range,1 -10 years), who were operated according to age and staging by Ficat or Catterall. The mean age of the patients was 35.3 years(range,4 -81 years). All patients were evaluated with both clinical and radiographical criterion. Results The postoperative excellent and good rate were 87.2% ,88.8% and 85.7% in each group respectively. The mean Hariss score increased (P <0.05) and the mean VAS score decreased (P < 0.05) in youth group and old group. Conclusions Children who were younger than six years of age and with Catter-all Ⅱ-Ⅲ involvement should be treated by ascularized iliac or greater trochanter bone periosteal flaps. Patients who were less than forty years of age, with Ficat Ⅱ-Ⅲ should be treated by ascularized iliac or greater trochanter bone flaps. For patients with age older than 50 years or younger than 50 years but with severe forms, hybrid or cememtless total hip arthroplasty may be the optimal operation.
