缝匠肌髂骨瓣治疗早期股骨头缺血性坏死疗效观察

目的探讨缝匠肌髂骨瓣植入治疗早期股骨头缺血性坏死的临床疗效。方法回顾性分析股骨头缺血性坏死56例的临床表现、影像资料和施行缝匠肌髂骨瓣植入的治疗效果。结果随访时间为8～36个月（平均18个月），术前应用Harris髋关节功能评价标准评分为（38．3±4．1）分，术后12个月Harris髋关节功能评分为（85．2±6．3）分，差异具有统计学意义（P〈0．01），其中优41例，良11例，一般2例，差2例，优良率为92．8％。结论缝匠肌髂骨瓣治疗股骨头缺血性坏死既重建了股骨头的血液循环，又提供了可替代坏死骨质的自体活骨，且取材方便，易于操作，是治疗早期股骨头缺血性坏死的良好方法。

Observation of curative effect of treating early avascular necrosis of femoral head by grafting sartorius mus-cle iliac bone flap

Objective To study the curative effect of treating early avascular necrosis of femoral head by grafting sartorius muscle iliae bone flap. Methods Since December 2006 to February 2010, 56 cases of avascular necrosis of femoral head （male 30 cases, female 26 cases） in the hospital were study. All cases were confirmed after comprehensive analyzing its clinical manifestations and image data. Fifty-six cases were cured with grafting sartorius muscle iliac bone flap into groove of femoral head and neck, Results The follow-up of the 56 patients during 8 months to 36 months （with an average of 18 months） revealed that based on the Harris evaluation for the hip function, the scores preoperative was （38.3 ＋4. 1 ） points and 12 month postoperative scores was （85.2 ＋ 6. 3 ） points. The result of T chest showed （P 〈 0. 01 ）. The results showed excellent therapeutic result in 41 cases, good in 11 cases, fair in 2 eases and poor in 2 cases, the excellent and good rate was 92. 8%. Conclusion This method treating early avascular necrosis of femoral head by grafting sartorius muscle iliac bone flap has not only reconstructed the blood circulation of femoral head, but also provided autologous live bone which can alternative necrotic bone. Sartorius muscle iliac bone flap can be acquired conveniently. So it is a good treatment method for treating early avascular necrosis of femoral head.
