Abstract：Objective To compare the long-term efficacy and complications between the single expansive open-door laminoplasty with miniature plate internal fixation and the total laminectomy with lateral mass screw internal fixation in treat-ment multi-segmental cervical spondylotic myelopathy. Methods We retrospectively analyzed the clinical data of 51 patients from 2010 to 2014 who had posterior cervical surgery in our department. Group A had 27 cases cervical posterior single open-door laminoplasty with mini plate internal fixation and group B had 24 cases total laminectomy and lateral mass screw fixation. We compared the operation time,bleeding volume,the ranges of cervical movement(ROM),the JOA score and the axial symp-toms after operation between these two groups. Results There was no significant difference between the operation time,bleed-ing volume. The ranges of cervical movement of two groups were(40. 4 ± 11. 27)°,(32. 3 ± 10. 19)°15 months after operation, the difference was statistically significant. The JOA score in two groups were(12. 17 ± 1. 45),(11. 89 ± 1. 87)three months after operation and(13. 77 ± 0. 93),(12. 95 ± 0. 89)fifteen months after operation. The JOA score between preoperative and postoperative was statistically significant,there was no significant difference between two groups. The incidence of axial symp-toms in two group were 14. 8% ,29. 1% . The difference was statistically significant. Conclusion These two opreation can ef-fectively improve the patient's neurological symptoms. The single expansive open-door laminoplasty with miniature plate inter-nal fixation can retain more ranges of cervical movement and get low incidence of axial symptoms.
