偏心距的有效恢复对人工全髋关节术后功能康复的影响

目的：探讨人工全髋关节置换手术中股骨偏心距的有效恢复与髋关节功能康复的关系。方法：回顾性分析53例人工全髋关节置换手术患者临床资料，测量术后双侧髋关节股骨偏心距，应用Harris评分系统评价髋关节功能康复情况。结果：双侧偏心距差别〈4mm者32例，功能优良者占87．5％；而偏心距未达到有效重建者21例，功能优良者占61．9％，两者差异有统计学意义（P〈0．01）。结论：人工髋关节置换术中股骨偏心距的有效重建与髋关节功能恢复存在密切关系，重建良好者髋关节功能恢复满意率高。

Effect of eccentricity restoration on function recovery after artificial total hip arthroplasty

Objective:To investigate the relationship between the effective restoration of femoral eccentricity and the hip function rehabilitation.Methods:Retrospectively analyzed the data of 53 cases with total hip arthroplasty,measured bilateral femoral eccentricity after surgery,and evaluated the recovery situation of hip function with Harris evaluation system.Results:32 cases had difference of bilateral eccentricity as <4 cm,and 87.5% out of all cases had excellent function.While eccentricity reconstruction of 21 cases failed and 61.9% cases had excellent function.The difference was statistic significant(P<0.01).Conclusion:There is close relationship between the femoral eccentricity rebuilt and hip function rehabilitation,and the recovery rate of patients with excellent rebuilt is more satisfactory.
