title: Use of cervical vertebral maturation to determine skeletal age.
abstract: BACKGROUND
  The purpose of this study was to evaluate the validity of the cervical vertebral maturation (CVM) method as an indicator of skeletal age in the circumpubertal period by correlating it to the hand-wrist method (HWM).
  
  
  METHODS
  Hand-wrist and lateral cephalometric radiographs of 400 Chinese subjects were randomly selected. Their ages were 10 to 15 years for girls and 12 to 17 years for boys, so they were within the circumpubertal period. Skeletal ages were assessed according to the CVM method and the HWM.
  
  
  RESULTS
  The CVM was significantly correlated with HWM skeletal age (Spearman r = 0.9521 [boys] and 0.9408 [girls]). All patients in cervical vertebral stage 3 of the CVM corresponded to stages MP3-FG or MP3-G (around the peak of the growth spurt) in the HWM.
  
  
  CONCLUSIONS
  The CVM is a valid indicator of skeletal growth during the circumpubertal period, providing information for timing of growth modification.
