The cross-sectional area and the sagittal and transverse diameters of the spinal canal at the thoracolumbar junction were measured using high resolution thin-section computerized tomography images in 15 control subjects and 28 patients with traumatic injury to the spinal cord at the thoracolumbar junction. No significant difference between the control and study groups was found with regard to any of the three measures taken. With the exception of the sagittal canal diameter for the first lumbar vertebra, all the mean values were higher for the spinal cord injured group. The ratio of the sagittal to transverse diameter was larger for the control group; however, this difference also was not significant. These findings suggest no significant differences in the dimensions and shape of the canal at the thoracolumbar region between the spinal cord injured and control groups. In contrast to the cervical spinal canal, there appears to be no correlation between the spinal cord injury and the dimensions of the thoracolumbar spinal canal.
在15名对照受试者和28名胸腰段脊髓创伤性损伤患者中，使用高分辨率薄层计算机断层扫描图像测量胸腰段交界处椎管的横截面积以及矢状径和横径。在所采取的三项测量指标中，对照组和研究组之间均未发现显著差异。除第一腰椎的矢状径管外，脊髓损伤组的所有平均值均更高。对照组的矢状径与横径之比更大；然而，这种差异也不显著。这些发现表明，脊髓损伤组和对照组在胸腰段椎管的尺寸和形状上没有显著差异。与颈椎管不同，胸腰段椎管的尺寸与脊髓损伤之间似乎没有关联。
