摘要(Abstract)：
目的探讨THA术后股骨偏心距恢复的重要性及重建方法,恢复髋关节的软组织平衡。方法对73例单侧THA术患者进行随访,手术均采用髋关节后外侧入路。X线片上测量股骨偏心距及髋外展肌的力臂,使用Cybex测量髋外展肌力量,对X线片测量数据进行统计学处理。结果股骨偏心距是否能够重建与髋最大外展肌肌力存在显著性差别(t=3.859;P=0.002);髋关节外展活动范围与股骨偏心距存在明显回归相关关系(r=0.593,P<0.001)。结论THA术中重建股骨偏心距可以增加髋外展肌的力臂,改善髋外展肌的力量,增强髋关节的稳定性。术中应选用近似解剖颈干角的股骨柄假体,适当地增加假体颈的长度。
