Lumbar spinal stenosis (LSS) is a condition that increases in frequency with the aging of the spine and has adverse effects on the quality of life of individuals. Facet tropism (FT) refers to the difference in the orientation of the facet joints relative to each other in the sagittal plane. This situation may be due to a developmental defect or different stimuli. In many biomechanical studies in the literature, the relationship between FT and lumbar degenerative disorders has been investigated. In this study, we aimed to investigate whether there is a relationship between anteroposterior bone canal diameter and FT in LSS cases.
We retrospectively evaluated the CT and T2-weighted axial and sagittal magnetic resonance imaging of the lumbar region of 100 LSS patients who were operated on in our clinic between 2015 and 2017. For each patient, the facet joint angles, the degree of FT, and the AP diameter of the spinal canal were determined.
The cases were grouped according to FT types and no correlation was found between midsagittal bone spinal canal measurement and FT types. According to the results, no significant difference was found.
As a result, because of there is no relationship between midsagittal bone canal diameter and FT, we thought that FT may be both a part of the degenerative process and a congenital origin.
腰椎管狭窄症（LSS）是一种随着脊柱老化发病率增加且对个体生活质量有不良影响的疾病。关节突不对称（FT）是指关节突关节在矢状面相对于彼此的方向差异。这种情况可能是由于发育缺陷或不同刺激所致。在文献中的许多生物力学研究中，已经对FT与腰椎退行性疾病之间的关系进行了研究。在本研究中，我们旨在调查LSS病例中前后位骨管直径与FT之间是否存在关系。
我们回顾性评估了2015年至2017年在我们诊所接受手术的100例LSS患者腰椎区域的CT以及T2加权轴向和矢状面磁共振成像。对于每位患者，确定关节突关节角度、FT程度以及椎管的前后径。
根据FT类型对病例进行分组，矢状位骨椎管测量值与FT类型之间未发现相关性。根据结果，未发现显著差异。
因此，由于矢状位骨管直径与FT之间不存在关系，我们认为FT可能既是退变过程的一部分，也是先天性起源。
