The reproducibility of measurements of the lumbar spine taken from computed tomography (CT) scans was assessed. The overall variaton in 53 patients scanned on more than one occasion was only 2.8%. Factors which reduced the reproducibility were increasing angle of scan from the mid-discal plane, measurement of oblique structures and measurement of dimensions with soft-tissue boundaries. Measurements from 142 patients are presented and compared with both other published series and the results from 17 patients with spinal stenosis. Whereas the sagittal diameter of the bony canal and the interpedicular distance of the patients with spinal stenosis did not differ from the control group, a new measurement described in this paper, the oblique sub-facet distance, demonstrated significant differences between the two groups.
评估了从计算机断层扫描 (CT) 扫描中获取的腰椎测量值的可重复性。53 名多次扫描的患者的总体变异仅为 2.8%。降低可重复性的因素包括从椎间盘平面扫描的角度增加、斜结构的测量以及软组织边界的尺寸测量。本文介绍了对 142 名患者的测量结果，并与其他已发表的系列以及 17 名脊柱狭窄患者的结果进行了比较。尽管脊柱狭窄患者的骨性椎管矢状径和椎弓根间距离与对照组无差异，但本文描述的新测量值——斜关节突距离，在两组之间存在显著差异。
