摘　　要：目的探讨现代陶对陶界面人工髋关节术后早期脱位的发生率和影响因素。方法回顾性分析我院骨科2009年6月至2012年12月间行陶对陶的人工髋关节置换术患者192例（212髋）的资料,其中初次行人工髋关节置换术175例（195髋）,人工髋关节翻修17例（17髋）,从股骨头假体的大小和所采用的手术入路以及髋臼的方位三方面,分析对人工髋关节置换术后发生脱位的影响。结果本组患者平均随访28个月（3~42个月）,术后脱位率为0.47%（1/212）,其中初次全髋关节置换术（totalhiparthroplasty,THA）术后脱位率为0,翻修THA术后脱位率为5.89%（1/17）;无骨溶解,无假体松动,无陶瓷破裂等其他并发症。结论现代陶对陶界面THA采用大直径的股骨头、改良Hardinge入路且髋臼位置恰当,可降低人工髋关节置换术后的脱位率。Objective To assessed the early dislocation incidence and the risk factors for ceramic-on-ceramic THA system.Methods We retrospectively reviewed 192patients（212hips）between June 2009and December 2012,including 195（175patients）primary THA procedures and 17（17patients）revision THA procedures.We analyzed the factors,including the femoral head size,the surgical approach and the orientation of the acetabulum.Results All patients were followed up for an average of 2 8months（3~4 2months）.The incidence of dislocation after THA occurred was 0.47%（1/212）.The primary THA postoperative dislocation rate was 0,the revision THA was 5.89%（1/17）.All cases had no osteolysis,no aseptic loosening and no component fracture.Conclusion Modern ceramic on ceramic（COC） total hip arrhroplasty has a low dislocation rate,using the large diameter head,modified hardinge approach and the optimal orientation of the acetabular component.
