腰椎间盘前突的CT诊断及其临床意义

Clinical value of CT scan in diagnosing anterior herniation of lumbar intervertebral disc

目的 :探讨腰椎间盘前突或 /和侧前突的CT诊断及其临床意义。方法 :回顾性分析 5 6例腰椎间盘前突或 /和侧前突合并腰大肌和前纵韧带受累的CT表现。所有病例有腰背痛或腰腿痛 ,均行腰椎间隙横断面CT薄层平扫。结果 :5 6例共有 71个腰椎间盘前突或 /和侧前突 ,多发生于L3 4,共 5 1个 ;发生于L4 5有 16个 ;其它部位 4个。腰大肌受累 3 1例 ,前纵韧带受累 15例 ,两者均受累 10例。结论 :腰椎间盘前突或 /和侧前突可挤压推移腰大肌或前纵韧带 ,加上其化学或免疫的作用可导致腰背痛或腰腿痛。CT能较好地反映这些影像学改变 。

Objective:To study the value of CT scan in diagnosing anterior herniation of lumbar intervertebral disc.Methods:CT findings of 56 cases with anterior herniation of lumbar intervertebral disc were reviewed retrospectively.All cases underwent axial plain CT scanning with thin slice.Results:71 anterior herniations of disc were found in 56 cases,51 of 71 were found at the level of L 3 4 and 16 at the level of L 4 5 .Musculi psoas major were involved in 31,anterior longitudinal ligment in 15,and both were involved in 10 of 56.Conclusion:Anterior herniation of lumbar intervertebral disc can cause low back or leg pain and great attention should be paid to it.CT scan is a useful method in diagnosing anterior herniation of lumbar intervertebral disc,finding the features of involved musculi psoas major and anterior longitudinal ligment,and guiding clinical treatment.
