摘要
用脊髓型颈椎病患者的脊髓造影Ｘ光片分别测量椎管和脊髓的前后径、横径、面积。结果椎管和脊髓的前后径和横径之比均为１：０．５，椎管和脊髓的面积之比为１：０．３。提示脊髓型颈椎病其椎管狭窄不超过５０％时，脊髓不会受到损害。
The anteroposterior and transversal diameters and the areas of the spinal canal and spinal cord in cervical myelopathy were smeasured using CTM.The ratios of both the anteroposteior and transversal diameters of spinal canal to spinal cord were 1:0.5 and the ratio of spinal canal area to spinal cord area was 1: 0.3.The results suggest that spinal cord will not be damaged by quiet pressure if spinal canal stenosis is not more than 50%.
