Application of transposition of greater trochanter flap pedicled with branch of transverse lateral circumflex femoral vascular to repair the femoral head

目的 探讨带旋股外侧血管横支大粗隆骨瓣转移在股骨头重建中的临床应用及疗效。 方法 选择Ficat分期中Ⅲ～Ⅳ期成人股骨头缺血坏死病例 15例 ,施行病灶清除 ,采用带旋股外侧血管横支大粗隆骨瓣转移 ,重建股骨头。 结果 临床应用 15例 ,其中 12例获得随访 ,平均 2 9年 ,髋关节功能恢复满意 ,优良率达 75 5 %。 结论 股骨头缺血坏死病灶清除术后的骨缺损 ,采用带旋股外侧血管横支大粗隆骨瓣转移 ,重建股骨头 ,恢复髋关节功能 。

Objective To study the clinic effect of repairing the femoral head with the transposition of great trochanter bone flap pedicled with branch of transverse lateral circumflex femoral vascular Methods To opt the stage Ⅲ～Ⅳ cases of adult avascular necrosis of the femoral head, after cleared the pathological changes position, the transposition of greater trochanter bone flap pedicled with branch of transverse lateral circumflex femoral vascular were repaired the femoral head Results Twelve cases were subjected to a serial follow up (average 2 9 years). The function of hip joint were recover and the clinic good was seen. The excellent rate was 75 5% Conclusion The lack bone after the operation of avascular necrosis of the femoral head, appling with the transposition of greater trochanter bone flap pedicled with branch of transverse lateral circumflex femoral vascular to repair the femoral head, renew the function of hip joint Its an effective means to treat avascular necrosis of femoral head
