摘　　要：目的:探讨无症状中国人颈椎椎管及椎体矢状径的正常值的分布及其在发育性颈椎管狭窄(developmental cervical spinal stenosis, DCS)的意义。方法:选择2018年1月~2022年9月于宜昌市中心人民医院门诊行颈椎正侧位X线检查的2000名患者,年龄15~87岁,在X线片上测量C2~C7的颈椎管矢状径(sagittal developmental diameter of the cervical canal, SDD)、颈椎体矢状径(anteroposterior diameter of the vertebral body, VB),计算Torg-Pavlov比值(颈椎管矢状径/颈椎体矢状径),分析了C2~C7颈椎管矢状径的变化趋势。结果:纳入2000名无症状中国人参与研究,其中男性1155名,女性845名,平均年龄41.3岁。C2~C7的颈椎管矢状径分别为21.59 mm、17.93 mm、17.60 mm、18.05 mm、18.52 mm、18.12 mm,C2~C7的颈椎体矢状径分别为16.63 mm、18.52 mm、18.47 mm、18.48 mm、19.03 mm、19.69 mm。C2~C7的Torg-Pavlov比值分别为1.31、0.98、0.96、0.99、0.98,0.93。结论:结果显示在无症状中国人中C2椎管矢状径最大,C2~C4逐渐减小,C5~C7逐渐增大。当C3~C7的Torg-Pavlov比值分别小于0.76、0.74、0.76、0.77、0.73时可诊断各节段的DCS。Objective: Explore the distribution of normal values for the sagittal developmental diameter of the cervical canal (SDD) and anteroposterior diameter of the vertebral body (VB) in asymptomatic Chi-nese individuals, as well as their significance in developmental cervical spinal stenosis (DCS). Methods: From January 2018 to September 2022, 2000 patients aged 15~87 years who underwent cervical spine X-ray examination in the outpatient department of the Yichang Central People’s Hos-pital were included in the study. SDD and VB at C2~C7 were measured on X-ray films, and the Torg-Pavlov ratio was calculated to analyze the trend of the SDD at C2~C7. Results: 2000 asympto-matic Chinese individuals were included in the study, consisting of 1155 males and 845 females, with an average age of 41.3 years. The SDD from C2 to C7 was 21.59 mm, 17.93 mm, 17.60 mm, 18.05 mm, 18.52 mm, and 18.12 mm, respectively. VB from C2 to C7 was 16.63 mm, 18.52 mm, 18.47 mm, 18.48 mm, 19.03 mm, and 19.69 mm, respectively. The Torg-Pavlov ratio of C2 to C7 was 1.31, 0.98, 0.96, 0.99, 0.98, and 0.93, respectively. Conclusion: The results showed that in asymp-tomatic Chinese individuals, SDD was largest at C2, gradually decreasing from C2 to C4, and then gradually increasing from C5 to C7. When the Torg-Pavlov ratio of C3~C7 was less than 0.76, 0.74, 0.76, 0.77, and 0.73, respectively, DCS can be diagnosed for each segment.
