Lumbar spinal stenosis is one of the primary causes of low back pain and is one of the primary causes of spinal surgery. Lumbar spinal stenosis is classified as congenital, acquired and a combination of both. Although the symptoms of both groups are similar, their etiology and radiographic features demonstrate some differences. Our aim to compare morphological characteristics of congenital and acquired lumbar spinal. We have reviewed CT and T2 weighted MRI images of 100 lumbar spinal stenosis patients operated between the years of 2014-2018 in our clinic. For each patient; pedicle length, facet joint angles, the degree of facet tropism, the lateral recess height and ligamentum flavum thickening have been determined. In patients within the congenital lumbar spinal stenosis, pedicle length has significantly found to be shorter than the "acquired" group. There is no significant difference between the facet joint angles of neither group and the facet tropism degrees in many of the patients appear to be similar and "no type". No significant difference has been found in the statistical distribution of lateral recess height and thickening of ligamentum flavum in acquired lumbar spinal stenosis and congenital lumbar spinal stenosis patient groups. As a result of the evaluations of facet joint angles of both groups, more sagittalized facet joints are related to the development of congenital and acquired lumbar spinal stenosis. As a result of our study, we think that facet joint angle and tropism type is not a distinctive factor in congenital and acquired lumbar spinal stenosis etiology.
腰椎管狭窄症是引起腰痛的主要原因之一，也是脊柱手术的主要原因之一。腰椎管狭窄症分为先天性、获得性和两者结合。尽管两组的症状相似，但它们的病因和影像学特征表现出一些差异。我们旨在比较先天性和获得性腰椎管狭窄的形态学特征。我们回顾了 2014 年至 2018 年间在我院接受手术治疗的 100 例腰椎管狭窄症患者的 CT 和 T2 加权 MRI 图像。对于每个患者，我们确定了椎弓根长度、关节突关节角度、关节突倾斜程度、侧隐窝高度和黄韧带增厚。在先天性腰椎管狭窄症患者中，椎弓根长度明显比“获得性”组短。两组的关节突关节角度没有显著差异，许多患者的关节突倾斜程度似乎相似，为“无类型”。在获得性腰椎管狭窄症和先天性腰椎管狭窄症患者组中，侧隐窝高度和黄韧带增厚的统计分布没有显著差异。由于对两组关节突关节角度的评估，更多矢状化的关节突关节与先天性和获得性腰椎管狭窄症的发展有关。根据我们的研究，我们认为关节突关节角度和倾斜类型不是先天性和获得性腰椎管狭窄症病因的一个独特因素。
