峡部裂性与退变性腰椎滑脱性别、年龄及发病部位的分析

Comparison of Gender,Age and Diseased Part between Patients with Isthmic Spondylolisthesis and Patients with Degenerative Lumber Spondylylisthesis

目的初步探讨峡部裂性腰椎滑脱(spondylolysis of lumbar spondylolisthesis,SLS)和退变性腰椎滑脱(degenerative lumber spondylylisthesis,DLS)发病部位与性别、年龄的关系。方法选取178例经CT确诊的腰椎滑脱患者,其中峡部裂性腰椎滑脱患者94例(SLS组),DLS患者84例(DLS组),分别整理、分析2组患者性别、年龄、发病部位等资料。结果 SLS组男女比4351;DLS组男女比417。SLS组的年龄小于DLS组[(55.31±11.33)岁比(64.00±10.89)岁,u=5.21,P<0.01)]。SLS和DLS在不同部位患病率差异有统计学意义(χ2=39.666,P=0.000);SLS发病部位与性别差异无统计学意义(χ2=3.156,P=0.076),DLS发病部位与性别差异有统计学意义(χ2=3.878,P=0.049)。结论 SLS好发L5,男女无显著差异;DLS好发于L4,女性明显多于男性;SLS发病年龄早于DLS。

Objective To investigate the relationships of diseased part to the gender and age in patients with spondylolysis of lumbar spondylolisthesis（SLS）or degenerative lumbar spondylylisthesis（DLS）.Methods The gender,age and diseased part were analyzed in 178patients with CTconfirmed lumbar spondylolisthesis（94patients with SLS and 84patients with DLS）.ResultsThe male-to-female ratio was 4351in SLS group and 417in DLS group.Compared with DLS group,the mean age of patients significantly decreased in SLS group[（55.31±11.33）years vs（64.00±10.89）years,u=5.21,P〈0.01].There was a significant difference in the incidence of lumbar spondylolisthesis in different diseased parts between the two groups（χ2=39.666,P=0.000）.The difference in diseased part between males and females was significant in DLS group（χ2=3.878,P=0.049）,but not significant in SLS group（χ2=3.156,P=0.076）.ConclusionThe SLS usually occurs at L5,and there is no significant difference between males and females.DLS usually occurs at L4,and females have a higher incidence of L4DLS than males.In addition,SLS occurs at an earlier age than DLS.
