【摘要】 在649名老年人的体检中,对有颈椎病症状的74人和无症状的52人抽样进行了X线平片检查及测量。测量结果:无症状组以C₄的椎管矢状中径最小,其余C_3～7均比较接近。有症状组的椎管矢状中径一般较无症状组小3 mm左右,而颈椎体的矢状中径都较后者大1mm左右。结果表明,无症状组C_3～7的比值皆大于0.75,而有症状组却有4处小于或接近0.75。根据本组资料来看,无症状组的软组织钙化发生率（50％）与有症状组（56.76％）差别不大。因此,有无软组织钙化,对于诊断颈椎病的价值可能不大。更多还原

【Abstract】 In a physical check-up of 649 aged persons, 74 cases with symptom of cervical spond yiosis and 52 cases without symptom were studied radiographically with measuremets of the sagittal middle diameter （SMD） of cervical spinal canal as chief criteria.The results show that in the asymp tomatic group the SMD of the cervical spinal canal of C₄ is the narrowest, while C₃～C₇ are of approximately equal size. In the symptomatic group, the SMD of the cervical spinal canal are about 3 mm less than that in the asymptomatic group.The SMD of the cervical vertebral body in symptomatic group are about lmm wider than that in the asymptomatic group.Ratio method was used to estimate the size of the cervical spinal canal so as to detecmine if there is a developmental stenosisThe results show that in the asymptomatic group, all ratio value from C₃ to C₇ exceeds 0.75, while in the symptomatic group the value is less than or near 0.75 at 4 levels.The calcification of soft tissue, especially the ligamentous calcification is a sign of-degeneration in bone and joint, and it is more prominent at advanced age.According to our data, the incidence of the soft tissue calcification shows little differece in the two groups Therefore, soft tissue calcification is of less significance in the diagnosis of cer vical spondylosis.更多还原
