Abstract:
[Objective]To compare the short term outcome in treatment of degenerative lumbar stenosis with Coflex implant versus laminectomy and posterior interbody fusion along with pedicle screw system. [Methods]Thirty patients with degenerative lumbar stenosis were randomly divided into two groups.Fifteen patients in the control group were treated with laminectomy and posterior interbody fusion along with pedicle screw system. The other 15 patients in the experiment group were treated with Coflex implant. The parameters for assessment included operation time,intraoperative blood loss,hospital stay,pre- and postoperative JOA score,improvement rate and complication rate.[Results]Compared to the control,significant reduction was found in terms of operation time,intraoperative blood loss,and hospital stay in the experiment group.No significant difference was found regard to the improvement rate and postoperative JOA score. In addition ,there was no complication in the Coflex group during the follow-up.[Conclusion]Coflex implant is an effective,save and minimally invasive surgical method for the treatment of degenerative lumbar stenosis.
