Clinci al application of minimally invasive Brachypodium hip replacement in traet ment of avascular nerc osis of femoral he ad

目的：评价微创短柄人工髋关节置换术治疗股骨头坏死的临床效果。方法：对我院2008年3月～2010年3月23例无菌性股骨头坏死病人行微创短柄人工髋关节置换术治疗，术后进行临床结果分析和评价。结果：23例均获得随访，平均随访36个月，按照Harris[1]评分标准评分：优18，良4，可1，差0．优良率为95．6％。结论：保留了股骨颈的短柄人工髋关节置换术，更符合人体生物力学特点，术后并发症低，为中青年股骨头坏死患者的治疗提供了一个新方法。

Objective：To evaluate the clinical effect of minimally invasive Brachypodium hip replacement in the treatment of avascular necrosis of the femoral head .Methods：23 aseptic osteonecrosis cases were treated with Brachypodium hip replacement surgery from March 2008 to March 2010, and analysis and evaluate the operation outcomes .Results：All cases were followed up for an average 36 months, ac-cording to Harris[1] Grading rating：18 excellent, 4 good,1 ok, no poor, excellent rate 95.6%.Conclu sion ：The minimally invasive Brachypodium hip arthroplasty could retain femoral neck , which conform to biomechanics , reduce postoperative complications .It might be a new approach for young patients with osteonecrosis .
