目的：分析比较≥65岁老年退变性腰椎滑脱症（ degenerative lumbar spondylolisthesis ， DLS）患者与同年龄段无滑脱人群的脊柱骨盆矢状面参数。方法选择2004年1月～2014年1月间于本院就诊，影像学资料完整，无峡部裂、椎体肿瘤，椎体结核、椎体压缩性骨折等疾病，且无腰椎手术史的≥65岁的DLS患者50例为滑脱组。以相同纳入标准选择50例年龄性别匹配的无腰椎滑脱的老年人为对照组。测量滑脱组患者腰椎滑脱椎间盘角和滑脱率均值，再测量并比较2组患者的腰椎前凸角（lumbar lordosis，LL）、骨盆入射角（pelvic incidence，PI）、骨盆倾斜角（pelvic tilt，PT）和骶骨倾斜角（ sacral slope ，SS）。滑脱组内再按性别分组比较各参数，并分别计算2组患者各参数间的相关性。结果滑脱组患者滑脱椎间盘角为7．4°±5．2°，滑脱率为（22．5±9．5）％。滑脱组患者的LL、PI、PT、SS均明显高于对照组。滑脱组内分性别比较时，滑脱参数和腰椎矢状面参数差异均无统计学意义。结论老年DLS患者较同龄无腰椎滑脱人群有着更大的LL、PI、PT、SS。性别因素可能对老年DLS患者的滑脱参数和主要脊柱骨盆矢状面参数无显著影响。

Objective To compare sagittal spinopelvic parameters between elderly degenerative lumbar spondylolisthesis (DLS) patients and age-matched non-DLS people.Methods A total of 50 elderly DLS patients(≥65 years),and 50 age-and sex-matched non-DLS patients hospitalized in department from January 2004 to January 2014 were included as DLS group and non-DLS group, respectively, after excluding patients with isthmic spondylolisthesis , spinal tumor or tuberculosis , vertebrae compressive fracture, severe arthritis in lower extremities and history of spine surgery .Mean slip angle(SA) and slippage (Slip%) of DLS group were calculated, lumbar lordosis(LL), pelvic incidence(PI), pelvic tilt(PT), sacral slope(SS)were compared between DLS and non-DLS group.In DLS group, all parameters were further compared by gender .Correlations between all parameters in both group were also calculated .Results SA and slip%were 7.4°±5.2°and (22.5 ±9.5)%, respectively.Significantly greater LL、PI、PT、SS were found in elderly DLS patients than age-matched non-DLS people. Comparison of SA, Slip%, LL, PI, PT, SS by gender in DLS group showed no significance .Conclusion Elderly DLS patients have greater sagittal spinopelvic parameters , such as LL, PI, PT, SS, than age-matched non-DLS people.In elderly DLS patients,gender factor may not be a influential factor of spondylolisthesis and main sagittal spinopelvic parameters .
