[摘要] 目的 探讨发育性颈椎管狭窄在脊髓型颈椎病的患病率及其相互关系。方法 测量从2009年1月—2013年12月收治52例脊髓型颈椎病患者 C3～C7的 椎管矢状径及椎体矢状径，得出其比值，比值>0.75为正常，≤0.75为发育性颈椎管狭窄，了解全部患者及接受手术患者中合并椎管狭窄的患病率。 结果 52例患者中有35例合并发育性颈椎管狭窄，占67%；35例接受手术患者中共28例合并颈椎管狭窄，患病率达到81%，且手术患者椎管矢状径、椎体矢状径，比值均小于全部患者值。结论 发育性颈椎管狭窄是脊髓型颈椎病发病的重要诱发因素，尤其在手术患者中明显。

    [Abstract] Objective To study the morbidity and correlation between the cervical spondylotic myelopathy and developmental cervical spinal stenosis. Methods The sagittal diameter of spinal canal and sagittal diameter of vertebral body of C3～C7 of 52 cases of patients with cervical spondylotic myelopathy admitted and treated in our hospital from January 2009 to December 2013 were measured and the ratio > 0.75 was normal ......
