摘 要：[目的]探讨髋臼钛板加颗粒植骨治疗髋臼严重骨缺损的临床效果。[方法]应用该技术治疗27例患者，髋臼骨缺损分型(AAOS分类)Ⅰ型6例，ⅡC型4例，Ⅲ型17例；术前髋关节Harris评分平均37分，术后根据临床及X线进行评估。[结果]所有患者均采用该方法重建髋臼，术后假体脱位1例，原因是重建钛板前倾过多与大粗隆发生撞击，经凿去部分粗隆骨质消除撞击因素后治愈。其余病例无并发症，平均随访3 a，Harris评分平均87分。X线无1例患者的髋臼骨床、移植骨、重建钛板和聚乙烯内衬交界面出现透亮带。[结论]髋臼钛板加颗粒植骨可有效修复髋臼骨缺损，为假体提供坚强的初始固定，具有恢复髋关节旋转中心的作用。关键词：骨缺损；髋臼；髋臼钛板；颗粒植骨；翻修术

Abstract：[Objective]To explore the clinical effects of titanium plate and morselized hone grafting for the treatment of severe acetabular hone defect[Method]A total of 27 patients with acetabular defects were treated with this procedureAccording to AAOS,the acetabular defects were classified into various types:type Ⅰ in 6 cases,type Ⅱc in 4 and type Ⅲ in 17The average preoperation Harris score were 37The postoperative effect should be evaluated by clinical and Xray manifestations[Result]All patients were adopted this method to reconstruct the acetabular bone defectsThe prosthetic dislocation was found in one case after operation,which was resulted from overanteverted titanium plate impacted the greater trochanterThe part of trochanteric bone and impact factors were removed to healingNo complications were found in other patientsThe average following up was 3 years and average Harris score was 87The Xray showed that none of the patients was presented the radiolucent lines in the acetabular mattress,bone transplantation,reconstructive titanium plate and interface of polyethylene liner[Conclusion]The titanium plate and morselized bone grafting can repair the acetabular bone defects effectively and provide a solid initial fixation for prosthesis and restore the role of rotational center of hip ......
