title: [Keyhole partial laminectomy and tapping technique combined blind transpedicular screw placement in cervical spine].
abstract: OBJECTIVE
  To investigate the clinical efficacy and safety of keyhole partial laminectomy and tapping technique combined blindly transpedicular screw placement in cervical spine.
  
  
  METHODS
  Keyhole partial laminectomy and tapping technique combined blindly transpedicular screw placement, was introduced. It was performed in 40 patients. The fusion and screw position were observed in postoperative X-ray and CT, and the breach of pedicle were evaluated. Neurological improvement was followed up.
  
  
  RESULTS
  Thirty-one cases were followed up, the mean follow-up period was 35 months. 28 cases screw fixation firmly and fusion completely, 3 cases fusion partly and no screw loosening. only 6.74% had a critical breach. Neurological function were improved in 29 cases of spinal cord injuries, only critical complication in one case.
  
  
  CONCLUSIONS
  Keyhole partial laminectomy and tapping technique. combined blind placement is one of most usefull, feasible and safe procedures in transpedicular screw placement of the cervical spine.
