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.

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C_4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。
