To explore morphological characteristic and development regularity of lower cervical pedicle in children.MSCT date of cervical were collected from 60 healthy 4~12 years old children, divided into three groups with each 20 cases, then imported into Mimics for reconstruction, measured pedicle width (PW), pedicle height (PH), the length of pedicle osseous channel (POCL), e angle and f angle of C3~C7 and calculate the PW / PH (I value), Statistical analysis by group and segment.
