title: [Progress of bone cement augmentation of pedicle screw].
abstract: OBJECTIVE
  To review the progress of the pedicle screw augmentation technique by bone cement.
  
  
  METHODS
  Recent literature about the pedicle screw augmentation technique by bone cement was reviewed and analysed. The characters were summarized.
  
  
  RESULTS
  Pedicle augmentation technique includes the augmentation of ordinary solid pedicle screw and hollow pedicle screw. Both types could increase the fixation strength and gain satisfactory clinical results. Bone cement leakage had a certain incidence rate, but most of cases were asymptom.
  
  
  CONCLUSIONS
  Bone cement augmentation of pedicle screw is an effective and safe internal fixation for poor bone condition.
