Abstract:Objective To explore the clinical treatment effect and long-term prognosis of cervical spondylotic myelopathy in patients with cervical spondylotic myelopathy by different surgical methods. Methods Patients were divided into two groups. The first group, anchor suspension group (AS group): anchor suture fixation in posterior cervical single-door laminoplasty The patients in this group were treated. The second group, TP group: titanium plate fixation treatment. 45 cases. The differences of neurological function, axial symptoms, opening angle and lateral axis fusion rate between AS group and TP group were analyzed by anchor suspension method and titanium plate fixation method to explore the posterior cervical single-door laminoplasty. Therapeutic effect and long-term prognosis of patients with cervical spondylotic myelopathy. RESULTS There was no difference in JOA scores between the two groups before and 1 year after operation. The JOA scores of the two groups were higher than those of the two groups . There was no difference in the improvement rate of neurological function between the two groups..One year after operation, 11 patients in the TP group developed axial symptoms, accounting for 24.44%, and 26 patients in the AS group, accounting for 57.78%. There were differences between the two groups. CT measurements, 1 month and 1 year after surgery, the angle of comparison between the two groups increased , the two groups were lower than 1 month after surgery, but the TP group was still larger than the AS group .Conclusion In the posterior single-door laminoplasty, the titanium plate method is superior to the anchor suspension method, which is significant for the treatment of patients, and the overall effect was good in the long-term within one year, but the titanium plate method was better than the anchor suspension method.
