摘要(Abstract)：
目的: 探讨THA术恢复双下肢等长的重要性及方法。方法: 对 73例单侧THA术患者进行随访, 随访时间 21 ~76个月 (平均 38. 9个月 )。X线片测量下肢的长短及股骨偏心距, 对X线片测量数据进行统计学处理。结果: 术后 90. 4%的患者 ( 66例 ) 出现下肢长度差别, 两侧髋臼顶至泪滴连线距离差与肢体长度差存在明显负相关关系 (r=-0. 612, P<0. 001), 股骨偏心距与下肢长度差存在明显相关关系 (r=0. 434, P=0. 003)。结论: THA的肢体不等长问题不容忽视, 强调术前肢体长度及模板测量, 术中正确评估肢体长度, 可获得满意结果。
