〔摘要〕目的 研究全髋置换假体方位角与术后疗效的关系，并为临床提供评价标准。 方法 临床随访全髋置换术后患者352例，平均3年1个月，采用Harris评分法评估术后疗效，测量术后及近期X线片髋臼前倾角、外展角、股骨头旋转中心位置及偏心距，并进行统计学分析。 结果 全髋置换术患者优良率为93.0%（Harris评分>80分）。352例中脱位10例，有中度及以上疼痛者16例。优秀组（Harris评分>90分）具有最为合适的方位角。前倾角<15°及外展角>56°者脱位发生率显著增加。疼痛组股骨头旋转中心的偏心距明显大于优良组。 结论 全髋置换术的疗效与髋臼前倾角、外展角、股骨头旋转中心及偏心距密切相关，前倾角在15°～25°、外展角45°～56°及合适的股骨头旋转中心位置和偏心距者术后疗效满意。

Effect of the prostheses position and orientation on total hip arthroplasty

Abstract:Objective A group of patients who had been applied total hip arthroplasty were followed up clini-cally and radiolocally to explore the effect of prostheses position and orientation on total hip arthroplasty，by the measurement of the anteversion angle，the abduction angle，the position of the femoral head center and the femoral offset which could be used as a basis to evaluate clinical practice.Method A series of370hip joints（352pa-tients）were followed up.The average follow up period was37monthes.Harris evaluation systemwas used，and the anteversion angle，the abduction angle，the position of the femoral head center and the femoral offset were measured with AutoCAD2005.The results were statistically analyzed，with a P value less than0.05indicating significant dif-ference.Results 93.0%patients got the Harris score more than80.Ten patients were found to have dislocation and16patients showmoderate or severe painness.Patients who got the Harris score higher than90had the most ap-propriate position and orientation of the prostheses.The anteversion angle less than15°or the abduction angle more than56°was found to be associated with the greater risk of dislocation.The large femoral offset was associated with severe pain.Conclusion Based on the results of the study，the anteversion angle，the abduction angle，the position of the femoral head center and the femoral offset should be considered as the most important factors of the healing ef-fect after total hip arthroplasty.We believe that the position and orientation of the prostheses should be controlled appropriately:the anteversion angle in the range from15°to25°，the abduction angle in the range from45°to56°，the appropriate position of the femoral head center and the femoral offset.

随着人工关节生物力学和材料学的迅速发展，全髋关节置换技术日趋成熟，并为越来越多的人们所接受。为了探讨全髋关节置换手术与髋臼假体的放置对患者术后疗效的影响，作者对352例（370髋）全髋置换病例随访结果进行回顾性分析，结合临床表现及放射学指标，总结全髋关节置换假体方位角对术后关节功 能的影响，并为临床提供评价标准。
