Abstract:

Objective To investigate the medium and long⁃term efficacy of posterior percutaneous endo⁃ scopic cervical discectomy（PPECD）in the treatment of cervical spondylotic radiculopathy. Methods A total of 62 patients with cervical spondylotic radiculapathy treated in our hospital from Jan 2018 to Jan 2019 were selected According to different surgical methods，the patients were divided into PPECD group（30 cases），and anterior cervical discectomy and fusion（ACDF）group（32 cases）. Perioperative indexes，clinical efficacy score，cervical curvature and intervertebral height of lesions were compared between the two groups. Results PPECD group had shorter operation time，less bleeding and shorter hospital stay. Postoperative follow⁃up showed that VAS score and NDI score in the two groups were significantly improved when compared with those before the operation ，with the difference statistical significance（P < 0.05）. The cervical curvature Cobb angle and diseased intervertebral height were significantly increased in the ACDF group，and the differences were statistically significant（P < 0.05）， while there was no significant change in the PPECD group. Conclusion With shorter operation time，less bleeding and shorter hospital stay，the medium and long⁃term efficacy of PPECD in the treatment of cervical spondylotic ra⁃ diculopathy is similar to that of ACDF.
