摘要：[目的]介绍髋臼翻修术中采用颗粒骨移植的方法处理骨缺损的体会。[方法]2001年1月~2004年12月，本院采用颗粒骨植骨行髋臼假体松动合并骨缺损的髋关节翻修术23例。男14例，女9例;年龄41~76岁，平均563岁。按美国骨科医师学会(AAOS)分类标准Ⅰ型5例；Ⅱ型12例；Ⅲ型5例;Ⅳ型1例。手术中假体骨水泥固定5例，非骨水泥固定18例。[结果]颗粒骨植骨术后X线检查骨愈合良好，包容假体牢固，原骨缺损区骨质得以修复。翻修前Harris评分平均为42分，术后随访平均为85分。[结论]髋臼翻修中采用自体或异体颗粒骨移植修复骨缺损，行挤压植骨可使颗粒骨与假体金属表面直接接触。观察证明移植颗粒骨生长好，达到了修复骨缺损和固定假体的目的。关键词：人工髋关节翻修术；骨移植；假体松动；骨水泥；骨缺损

Abstract：[Objective]To report the experience of the revision procedure with morselized bone for loosened acetabular component[Method]Since January 2001 to December 2004,23 cases with loosened acetabular component and bone defect were revised by morselized bone auto/allograftingThere were 14 males and 9 females,the average age of patients was 563 years old(form 41 to 76 years old)The severity of acetabular component loosening was classified according to American Academy of Orthopaedic Surgeons(AAOS):TypeⅠ5 cases,TypeⅡ 12 cases,Type Ⅲ 5 cases and TypeⅣ 1 caseCement was used in 5 cases and no cement was used in 18 cases[Result]All of the bone grafts healed well and Xray showed that the containing of acetabular component was good,no translucent line between donor bone bed and prosthesis,and the bone defect had been repairedThe average Harris score was 42 before revision,and 85 after revision[Conclusion]Direct contact between the morselized bone auto/allograft and the surface of metal acetabular component and the firm fixation of the prosthesis have showed good result of bone defect reconstruction ......
