摘　　要：目的探讨腰椎前凸度(LLA)及骶骨水平角(SHA)大小与腰椎退变性滑脱(LDS)程度的关系。方法采用中立站立位X线摄片,在医学影像存档与通信系统(PACS)上测量LLA、SHA大小和滑脱距离。比较LDS组和正常对照组的LLA值和SHA值,统计120例LDS患者各腰椎的退变性滑脱发生率,并对LLA、SHA和滑脱程度的相关性进行PEARSON相关分析。结果 LDS组的LLA值和SHA值均高于对照组,差异均有统计学意义(t分别=8.84、9.66,P均<0.05);各腰椎的退变性滑脱发生率显示:腰椎(L)4的退变性滑脱发生率最高,达55.83%,次高为L5,为29.17%,L1最低,为0.83%;Pearson相关分析:LA与退行性脊柱滑脱距离具有相关性(r=0.19,P<0.05);SHA与退行性脊柱滑脱距离具有相关性(r=0.19,P<0.05);LDS患者的LLA与SHA具有相关性(r=0.83,P<0.05)。结论 LLA及SHA与LDS滑脱距离具有相关性,可能是LDS的原因之一。Objective To investigate the relationship between lumbar lordosis angle（LLA）,sacral horizontal angle（SHA） and lumbar degenerative spondylolisthesis（LDS）.Methods Neutral erect lateral lumbar radiographs were obtained from 120 patients with LDS and 120 without LDS.Radiographs were viewed in the network monitor and the angles and the slipped distance of lumbar were directly measured by computerized goniometer of the Picture Archiving and Communication System（PACS） software.Statistical analysis was taken by the data we achieved.Results The LLA and SHA had significant differences between 120 patients with LDS and 120 without LDS（t =8.84,9.66,P〈0.05）.There were significant positive correlations between LLA and LDS（r=0.19,P〈0.05）.There were significant positive correlations between SHA and LDS（r=0.19,P〈0.05）.Conclusions The LLA and SHA were significantly correlated with lumbar degenerative spondylolisthesis.The increased LLA and SHA maybe is an important factor in the aetiology of LDS.
