峡部裂性与退变性腰椎滑脱性别、年龄及发病部位的分析

摘要

Objective To investigate the relationships of diseased part to the gender and age in patients with spondylolysis of lumbar spondylolisthesis(SLS)or degenerative lumbar spondylylis-thesis(DLS).Methods The gender,age and diseased part were analyzed in 178 patients with CT-confirmed lumbar spondylolisthesis(94 patients with SLS and 84 patients with DLS).Results The male-to-female ratio was 4351 in SLS group and 417 in 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).Conclusion The 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 L4 DLS than males.In addition, SLS occurs at an earlier age than DLS.%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（de-generative 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。
