Abstract: BACKGROUND: Anterior approach and posterior approach are used in the treatment of multilevel cervical spondylotic myelopathy, but it is still controversial about the choice of surgical approach. 
OBECTIVE: To investigate the effects of anterior corpectomy and fusion versus posterior single open-door laminoplasty on cervical range of motion of patients with multilevel cervical spondylotic myelopathy. 
METHODS: Medical records of patients with multilevel cervical spondylotic myelopathy admitted in Affiliated Hospital of Qinghai University from January 2016 to January 2018 were retrospectively analyzed. According to surgical approaches, they were divided into anterior and posterior groups. Patients in the anterior group (n=33) were treated with anterior corpectomy and fusion, while patients in the posterior group (n=32) were treated with posterior single open-door laminoplasty. The Japanese Orthopaedic Association score was used to evaluate the neurological function before and after surgery in both groups. Cervical range of motion before and after operation was measured in both groups.
RESULTS AND CONCLUSION: (1) A total of 65 patients with multilevel cervical spondylotic myelopathy were followed up. The follow-up time ranged from 12 to 25 months. (2) There were no significant differences in age, gender composition, follow-up time, and Japanese Orthopaedic Association score between the two groups before surgery and at the time of the last follow-up (P > 0.05). (3) Cervical range of motion of the two groups after surgery was reduced compared with those before surgery (P < 0.05). The ranges of motion of cervical spine in the posterior group were better than those in the anterior group in flexion, extension, left flexion, right flexion, left rotation and right rotation at the last follow-up. (4) It is indicated that the range of motion of cervical spine was reduced after both anterior corpectomy and fusion and laminoplasty in patients with multilevel cervical spondylotic myelopathy, and the former has more influence on the cervical range of motion than the latter.
