关节镜监视下带血管蒂大转子骨瓣转移治疗股骨头缺血性坏死

目的：报道结合应用关节镜经髋外侧入路治疗股骨头缺血性坯的显微外科手术方法。方法：在关节镜监视下经髋外侧入路应用带旋股外侧血管横支大转子骨瓣治疗早期病变的股骨头缺血性坏死26例。结果：术后随访1－3年，根据疼痛，行走距离，关节活动度，X线评价分析，取得了满意的治疗效果。结论：在关节镜监视下带血管蒂大转子骨瓣转移治疗股骨头缺血性坏死，可以在精确有效地清除病灶内坏死骨质的基础上重建股骨头的供血系统，同时经外侧入路可以进一步减少对髋周肌群及韧带的损伤。应用关节镜技术及显微方法是治疗股骨头缺血性坏死早期病变的简便有效方法。

Treating ischemic necrosis of femoral head with vascularized great trochanter bone flap graft under the surveillance of arthroscope

Objective To probe into the microsurgical method of using arthroscope in treating ischemic necrosis of femoral head(INFH) Method Twenty six cases (33 hips) with early stage of INFH were operated by vascularized greater trochanter bone flap graft through the lateral acetabulum approach under the surveillance of arthroscope Result The follow up ranged from 1 to 3 years Function evaluation was made according to pain,function,joint activity and radiographic criteria The clinical results were satisfactory Conclusion With this method, can accurately clean the sequestra and reconstruct the blood supplying system of femoral head At the same time, the injury of the peripheral muscle of hip joint and ligament can be further reduced and the function of hip joint can be recovered maximally So the method of applying arthroscope and microsurgical technique to treat early stage INFH is a simple, convenient and effective method
