The study protocol was approved by the Institutional Review Board of the study hospital. Signed informed consent was obtained from all participants in the study.

A total of 26 consecutive patients with multilevel DCM (≥ 3) were prospectively enrolled between October 2018 and May 2019. Patients with a history of other spinal disorders, neurological injury, infection, tumor, and rheumatoid arthritis were excluded. Finally, 22 patients (17 males and 5 females) who had been followed for 12 months were included in this study. The mean age at surgery was 61.2 ± 10.8 years and the average symptom duration was 42.95 ± 40.05 months (Table 1).
