Analysis of Curative Effect of Posterior Cervical Pedicle Screw Fixation Operation for Cervical Spondylotic Myelopathy / 沈阳医学院学报

ABSTRACT

Objective:To evaluate the clinical effect of posterior cervical pedicle screw fixation operation for cervical spondylotic myelopathy.Methods: From Mar 2014 to Sep 2015, 55 patients with cervical spondylotic myelopathy treated with posterior cervical pedicle screw fixation operation were involved. Cervical curvature in the cervical three dimensional CT by the Harrison’ s cervical curvature measuring method was measured, and JOA scores, NDI scores and VAS scores before and after operation and the last follow-up were evaluated. Results:A total of 55 patients with cervical spondylotic myelopathy obtained good operation effect and the cervical curvature and neural function were improved.The cervical curvature, JOA score, NDI scores, and VAS scores were significantly better than that before operation (P < 0.05) . Last follow-up results showed that there was statistical significance on JOA score, NDI score, and VAS score compared with that after operation (P<0.05), but not on cervical curvature (P>0.05) . Conclusion:The neurological function and cervical curvature of the cervical spondylotic myelopathy can be improved through posterior cervical pedicle screw fixation operation.
