１９７８～１９９２年共收治脊髓纵裂３９例，其中１７例术前行ＣＴ检查确诊。ＣＴ特征：椎管中央有纵行骨嵴将脊髓或马尾分隔，多数骨嵴两侧蛛网膜下间隙及脊髓不均称；该部椎管扩大；椎体及附件结构紊乱。ＣＴ不仅能准确诊断损害的平面，而且能显示椎管的自然状态和骨嵴的种类及轮廓。 From 1978 to 1992, 39 cases of spinal cord rupture were treated, of which 17 cases were diagnosed by CT before operation. CT features: the central longitudinal spinal canal will be separated from the spinal cord or cauda equina, the majority of both sides of the bone crest subarachnoid space and spinal cord asymmetry; the Ministry of spinal canal expansion; vertebral bodies and appendages disorder. CT can not only accurately diagnose the damage plane, but also shows the natural state of the spinal canal and the type and contour of the ridge.
