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.
