[摘要] 目的 研究偏心距重建对人工全髋关节置换术患者髋关节稳定性、活动度及关节功能的影响。 方法 将2012年4月~2014年5月在天津红桥医院接受髋关节置换术的120例患者纳入研究对象,根据偏心距重建情况筛选偏心距大于健侧组、偏心距小于健侧组、偏心距未重建组,每组各40例,检测髋关节稳定性、活动度及关节功能。 结果 ①髋关节稳定性、活动度:术后3、6个月时偏心距大于健侧组的单腿支撑相骨盆冠状面倾斜角、髋关节活动角度均大于偏心距小于健侧组、偏心距未重建组[骨盆冠状面倾斜角:术后3个月:(1.08±0.21)°比(-1.12±0.14)°、(-1.29±0.20)°;术后6个月:(1.22±0.20)°比(-0.89±0.11)°、(-1.05±0.14)°。髋关节活动角度:术后3个月:(13.95±1.57)°比(8.42±0.94)°、(6.13±0.77)°;术后6个月:(16.32±1.91)°比(12.23±1.56)°、(8.82±0.91)°],差异均有统计学意义(均P < 0.05)。②髋关节功能:术后3、6、12个月,偏心距大于健侧组的Harris评分高于偏心距小于健侧组、偏心距未重建组[术后3个月:(89.12±9.04)分比(78.32±9.16)、(73.56±8.52)分;术后6个月:(90.37±11.32)分比(83.42±10.06)、(76.23±8.23)分;术后12个月:(93.68±12.32)分比(86.26±9.31)、(79.48±9.04)分],差异均有统计学意义(均P < 0.05)。 结论 人工全髋关节置换术中偏心距重建且偏心距大于健侧有助于提高髋关节稳定性、活动度,改善髋关节功能。

[Abstract] Objective To study the effect of eccentricity reconstruction on hip joint stability, activity and joint function of patients received artificial total hip joint replacement. Methods 120 cases of patients received artificial total hip joint replacement from April 2012 to May 2014 in Tianjin Hongqiao Hospital were enrolled, eccentricity greater than contralateral group (40 cases), eccentricity less than contralateral group (40 cases), eccentricity without reconstruction group (40 cases) were screened according to eccentricity reconstruction condition. Then hip joint stability, activity and joint function were detected. Results ①Hip stability, activity: single leg support phase angle of inclination of pelvis coronary and hip joint angle in eccentricity greater than contralateral group were higher than those of eccentricity less than contralateral group and eccentricity without reconstruction group [angle of inclination of pelvis coronary: postoperative three months: (11.08±0.21)° vs (-1.12±0.14)°, (-1.29±0.20)°; postoperative six months: (1.22±0.20)° vs (-0.89±0.11)°, (-1.05±0.14)°. Activity angle of hip joint: postoperative three months: (13.95±1.57)° vs (8.42±0.94 )°, (6.13±0.77)°; postoperative six months: (16.32±1.91)° vs (12.23±1.56)°, (8.82±0.91)], the differences were all statistically significant (all P < 0.05). ②Hip joint function: the Harris scores of eccentricity greater than contralateral group were higher than those of eccentricity less contralateral group and eccentricity without reconstruction group [postoperative three months: (89.12±9.04) points vs (78.32±9.16), (73.56±8.52) points; postoperative six months: (90.37±11.32) points vs (83.42±10.06), (76.23±8.23) points; postoperative twelve months: (93.68±12.32) points vs (86.26±9.31), (79.48±9.04) points], the differences were all statistically significant (all P < 0.05). Conclusion Eccentricity reconstruction in total artificial total hip joint replacement is helpful to enhance stability and activity of hip, improve hip joint function.

全髋关节置换术是目前治疗晚期髋关节病变的主要手术方式,人工髋关节置换术的疗效受到了多种因素的影响,包括手术入路的选择、假体种类和位置、术前髋关节周围软组织条件、术前因髋部疼痛而产生的适应性步态特征等[1]。近年来研究认识到,偏心距也是影响人工髋关节置换术的疗效以及髋关节功能性、稳定性的因素之一[2]。偏心距重建不但能够恢复髋外展肌的力矩,进而增加髋关节的稳定性;且可缓解髋关节应力,减少磨损退变[3-4]。本文采取随机对照研究的方法,探讨偏心距重建对人工全髋关节置换术患者髋关节稳定性、活动度及关节功能的影响。……
