摘　　要：在Ｘ线侧位片上，颈椎管与其相应椎体矢状面直径的比率称为颈椎管率（Ｃｅｒｖｉｃａｌｓｐｉｎａｌｃａｎａｌｒａｔｉｏ）。笔者采用Ｔｏｒｇ等方法测量１００名正常国人颈椎管率的结果表明，Ｃ＿３为０．９６±０．０８，Ｃ＿４为０．９５±０．０８，Ｃ＿５为０．９６±０．０９，Ｃ＿６为０．９７±０．１０，平均为０．９６±０．０９。统计学分析显示Ｃ＿（３～６）间颈椎管率均无显著性差异（Ｐ＞０．０５）；男女颈椎管率则有非常显著性差异（Ｐ＜０．００１）。颈椎管率作为Ｘ线的一个定量指标，对于颈椎管狭窄的诊断具有一定的临床意义，且方法新颖、科学和实用。Sagittal spinal canal/vertebral ratios were measured on cervical spine lateral radiographs of 100 normal people using a new method by Torg et al. The ratio was 0.96± 0.08 for C_3,0.95± 0.08 for C_4,0.96± 0.09 for C_5<and 0.97± 0.10 for C_6 mean 0.96± 0.09. There was no statistically signifeant difference of spinal canal ratio from C_3 to C_6(P>0.05). However marked difference(P<0.001) was observed between the male and female groups from C_3to C_6. The ratio,as a quantita-tive parameter of X-ray examination has clinical value for diagnosing stenosis of cervical spinal canal.
