title: [Advance of lower cervical spine pedicle screw fixation in treatment of lower cervical spine instability].
abstract: OBJECTIVE
  To review the anatomic character of lower cervical pedicle, the placement and the biomechanical stability of the cervical pedicle screw fixation, the clinical application and the complication caused by fixation.
  
  
  METHODS
  The literature concerned the cervical pedicle screw fixation in recent years were extensively reviewed.
  
  
  RESULTS
  The cervical pedicle screw fixation can be widely used in the lower cervical spine instability according to the anatomic character of lower cervical pedicle, and the good biomechanical stability of the cervical pedicle screw fixation, and the complication can be controlled.
  
  
  CONCLUSIONS
  The cervical pedicle screw fixation is an effective internal fixation for the lower cervical spine instability.
