摘要
目的探讨人工全髋关节置换(THA)术中股骨偏心距(FO)重建后的临床效果。方法对67例行单侧THA的患者进行随访,测量对比指标为:手术前后的FO、髋外展肌力臂和双下肢长度、髋关节活动度及Harris评分。结果 67例患者中FO术后重建率83.6%(56/67)。术前髋外展肌力臂为53.67 mm±5.34mm,术后为58.32 mm±6.15 mm,差异有统计学意义(P<0.01)。56例FO重建患者术后髋关节活动度为179.15°±7.24°,术后Harris评分为96.5分±6.1分,11例FO未重建患者术后髋关节活动度为149.27°±7.35°,Harris评分为90.5分±5.8分;两者髋活动度、Harris评分比较差异均有统计学意义(P<0.01)。FO与髋外展肌力臂、髋关节术后活动度、Harris评分均呈正相关(P<0.01)。结论 THA术中FO重建与髋外展肌的力臂增加、髋关节的活动度、功能改善及稳定性增强呈正相关。THA术中FO重建是术后关节功能恢复的重要因素。
Objective To evaluate the clinical efficacy of femoral offset （FO）recovery and reconstruction in total hip arthroplasty （THA）.Methods In 67 cases of unilateral THA patients with follow-up,the contrast indexes were measured：FO before and after operation,hip abductor lever arm and leg length,hip joint activity and Harris score. Results The rate of FO recovery and reconstruction in 67 patients was 83.6% （56/67）.The abductor lever arm before THA was 53.67 mm ±5.34 mm,and it became 58.32 mm ±6.15 mm after THA with the statistical signifi-cance between them（P〈0.01）.The ROM of hip of the 56 patients whose FO was recovered to 179.15°±7.24°, the ROMof hip of the other 11 patient was 149.27°±7.35°.The Harris scores of the former was 96.5 ±6.1,and the scores of the latter was 90.5 ±5.8.There were both Statistical significance between them （P〈0.01 ）.Femoral offset was correlated significantly positively with the length of abductor lever arm,the ROM of hip and Harris scores （P〈0.01）.Conclusions FO reconstruction during THA is positively related to hip abductor lever arm increased, function improvement and enhancement of stability hip joint activities.FO reconstruction during THA is an important factor in the restoration of joint function after surgery.
