[摘要] 目的 探討退变性腰椎滑脱临床与影像学（CARDS）分型中各亚组患者在脊柱骨盆矢状位参数上的差异。 方法 回顾性分析 2018年1月至 2019 年12月我院收治的92例 L4～5单阶段退变性腰椎滑脱患者的临床资料。依据腰椎正侧位X线或动力位腰椎 X 线正侧位上滑脱节段椎间隙是否后凸成角分为D 型滑脱组和非 D 型滑脱组（即A、B、C三型）。术前、术后均测量入组患者的脊柱骨盆矢状位参数，同时采用 Oswestry功能障碍指数（ODI）和腰部疼痛视觉模拟评分法（VAS）对患者生活质量进行评估。 结果 术前D型滑脱组LL、PI、SS均显著低于非D型滑脱组，而PT显著高于非D型滑脱组，差异有统计学意义（P<0.05）。术前D型滑脱组ODI评分和腰痛VAS评分均显著高于非D型滑脱组，差异有统计学意义（P<0.05）。 结论 退变性腰椎滑脱CARDS分型中D型患者与非D型患者在脊柱骨盆矢状位参数存在差异，D型可以作为一种独特的亚型进行探讨，可以推广为临床常用的术前评估分类系统之一。D 型患者术前腰椎生理前凸丢失，容易表现出更严重的临床症状。

[Abstract] Objective To investigate the difference of sagittal parameters of spine and pelvis among different subgroups of patients in clinical and radiographic degenerative spondylolisthesis（CARDS） classification of degenerative lumbar spondylolisthesis. Methods The clinical data of 92 cases of patients with L4-5 single stage degenerative lumbar spondylolisthesis admitted to our hospital from January 2018 to December 2019 were analyzed retrospectively. According to whether the intervertebral space of the spondylolisthesis segment of the lumbar anteroposterior and lateral X-ray or the dynamic position lumbar X-ray anteroposterior and lateral was kyphosis or not， the patients were divided into the D-type spondylolisthesis group and the non-D-type spondylolisthesis group（namely type A， B and C）. The sagittal parameters of spine and pelvis were determined before and after operation，and the quality of life of patients was evaluated by oswestry disability index（ODI） and visual analogue scale（VAS） for lumbar pain. Results The LL， PI， SS in the D-type spondylolisthesis group were all obviously lower than those in the non-D-type spondylolisthesis group before operation， PT was obviously higher than that in the non-D-type spondylolisthesis group， with significant difference（P
