Long-term Results of Expansive Open-Door Laminoplasty for Cervical Myelopathy−Average 14-Year Follow-up Study

Abstract

Long-term results of open-door laminoplasty without bone graft, graft substitutes, or instruments were satisfactory. However, segmental motor paralysis, kyphosis, established before and after surgery, OPLL progression, and late deterioration due to age-related degeneration remain challenging problems.
