| 目的 应用骨盆半径（PR）技术分析退行性腰椎滑脱（DLS）与退行性腰椎椎管狭窄症（DSS）患者脊柱-骨盆参数的特点，并探讨其代偿机制。方法 回顾性分析2015年9月-2017年8月宁夏医科大学总医院收治的36例DLS和35例DSS患者的影像学资料。在站立位全脊柱侧位X线片上测量脊柱矢状面平衡（SVA）、总腰椎骨盆前凸角（PR-T12）、骨盆形态（PR-S1）、骨盆角（PA）、腰椎前凸（LL）和胸椎后凸（TK）。将2组所测参数分别与健康国人脊柱-骨盆参数进行比较，同时采用Pearson相关分析研究各脊柱骨盆-参数之间的相关性。结果 DLS组与DSS组中SVA、PA均明显大于正常参考值，差异有统计学意义（P < 0.05）。DSS组PR-T12明显小于正常参考值，DLS组PR-S1明显小于正常参考值，差异均有统计学意义（P < 0.05）。DLS组PR-T12与PA的相关性强于与LL、TK的相关性，DSS组PR-T12与LL、TK的相关性强于与PA的相关性。DLS组PR-S1与PA呈负相关，DSS组PR-S1与PA无相关性。结论 DLS患者可能主要通过骨盆后倾维持脊柱矢状位平衡，DSS患者可能主要通过改变胸腰椎曲度维持脊柱矢状位平衡。 |

| Abstract: |
| Objective To analyze the characteristics of spine-pelvis parameters with pelvic radius(PR) technique in patients with degenerative lumbar spondylolisthesis(DLS) and degenerative spinal stenosis(DSS),and to explore the compensatory mechanism. Methods From September 2015 to August 2017,the imaging data of 71 patients who were diagnosed as having lumbar degenerative spondylolisthesis(36 cases) or degenerative spinal stenosis(35 cases) in General Hospital of Ningxia Medical University were retrospectively reviewed. The following spinopelvic parameters were measured on whole spine lateral radiographs in a standing position:sagittal vertical axis(SVA),total lumbopelvic lordosis(PR-T12),pelvic morphology(PR-S1),pelvic angle(PA),lumbar lordosis(LL) and thoracic kyphosis(TK). All the parameters from the DLS and DSS group were compared with the normal parameters of Chinese population,respectively. Correlations between the spinopelvic parameters of the 2 groups were determined using Pearson correlation coefficient. Results The SVA and PA in the DLS and DSS group were significantly higher than the normal values,and the differences were statistically significant(P < 0.05). PR-T12 of the DSS group was significantly lower than the normal value,PR-S1 of the DLS group was significantly lower than the normal value,both with statistical significances(P < 0.05). In the DLS group,PR-T12 was more strongly correlated with PA than with LL and TK. In the DSS group,PP-T12 was more strongly correlated with LL and TK than with PA. PR-S1 was negatively correlated with PA in the DLS group,but not in the DSS group. Conclusion DLS patients may maintain sagittal spinal balance mainly through backward pelvis,while DSS patients may mainly by changing the curvature of thoracolumbar spine. |
