摘要
目的 评价盘黄间隙对腰椎间盘突出的诊断价值。材料与方法 回顾性分析２００例腰椎间盘ＣＴ扫描资料，记录Ｌ３－Ｓ１间盘形态及双侧黄韧带厚度、盘黄间隙的宽度，分析这些结构与盘黄间隙狭窄及其对腰神经根压迫的关系。结果１９６个间盘突出或膨出，７８处黄韧带厚度＞５ｍｍ，腰盘黄间隙（ＤＦＬＳ）为腰间盘平面位于椎管外侧份间盘与黄韧带间的间隙。１７２侧显示腰神经根鞘受压，相应盘黄间隙平均宽度为（３．６± ０．８）ｍｍ。结论 ＤＦＬＳ＆ｐｏｕｎｄ；５ｍｍ为狭窄，主要原因包括；间盘突出或膨出、黄韧带肥厚等。它可以作为腰间盘突出伴神经根压迫的可靠依据。
Objective TO measure the width of disk-fiavum ligamentum spase(DFLS) and evaluate it's value in diagnose of herniation of intervertibral disk. Materials and Methods The image of CT in lumbar intervertibral disk of 200 cases were retrospectively analyzed; and the shapes of L3-S1 disk, the width of flavum ligmenta at each side and that of DFLS were recorded.. The relation of the restructions and parameters to DFLS stenosis and the compressed lumbar nerve roots shown in CT were analyzed. Results The herniation or bluging of intervertibral disk were found in l96 level; 78 flava ligments width>5mm; 172 of 200 cases of mean width DFLS (3.60.8)mm. Conclusion The DFLS£5mm can be diagnosed stenosis. The main causes of stenosis are herniation or bluging of intervertibral disk, flava ligamen thicker. It can be used as a valuable criterion diagnosing lumbar nerve boot compression in CT study.
