摘要
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 elder]y 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 DIS group and non-DLS group, respectively, ＇alter 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.
