    Abstract:
    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.
