title: [Research of open situation x-ray of cervical vertebra in healthy people].
abstract: OBJECTIVE
  To investigate the incidence rate of the different width in two sides of vertebra and C2 spinal process tilt, and analyze the different incidence rate between the unusual change of open situation x-ray and migraine.
  
  
  METHODS
  Among the 350 investigators, testing the open situation x-ray of cervical vertebra and the questionnaire of migraine situation (163 male and 187 female with an average age of 39.6 years ranging from 26 to 54 years). They were divided into several groups according to the age, including 94 people from 26 to 34 years, 103 people from 35 to 44 years, 153 people from 45 to 54 years. The method of contrasting the incidence rate of open situation x-ray with the rate of migraine was used.
  
  
  RESULTS
  Among the 350 investigated people, the incidence rate of the different width in two sides of vertebra and C2 spinal process tilt was 32.28%. The relationship between the different width in two sides of vertebra and the rate of migraine is not obvious (P > 0.05). However,the relationship between C2 spinal process tilt and the migraine was obvious (0.05 > P > 0.01).
  
  
  CONCLUSIONS
  The difference between the different width in two sides of vertebra and the rate of migraine is not obvious in the investigated people, so it is not reliable to diagnose the illness as cervical vertebra disease. While the difference between the C2 spinal process tilt and the migraine is obvious, it is one of the reasons to diagnose the migraine.
