人工全髋关节置换术后关节脱位与手术入路的临床分析

Clinical Analysis of Dislocation and Operative Approach after Artificial Total Hip Arthroplasty

目的人工全髋关节置换术后关节脱位与手术入路的临床分析与比较。方法对我院240例髋关节置换病人采取不同手术入路易发髋关节脱位进行统计及分析。结果关节脱位原因很多,但手术入路针对不同适应证的选择及术中操作技巧以及假肢安放位置的不正确,可导致髋关节脱位的几率明显提高。结论髋关节后外侧入路针对不同疾病治疗确实存在着不同的脱位几率。另外,如假体因素等,也相应对术后脱位并发症产生一定的影响。

Objective Clinical analysis of dislocation and operative approach after artificial total hip arthroplasty. Methods 240 cases of such patients in our hospital were admitted different operative approach. The results were statistic and analyzed. Results Dislocated has a lot of reasons. However, the choice of operative approach, operative technique and the incorrect implant position of prosthesis raise hip joint dislocation obviously. Conclusion Hip arthroplasty posterolateral approach has different dislocation rate for different disease. Further more, other factor such prosthesis also has some influence.
