Clinical Outcome of Cervical Laminoplasty and Postoperative Radiological Change for Cervical Myelopathy With Degenerative Spondylolisthesis.

摘要: Study design A retrospective cohort study with prospectively collected data. Objective The aim of this was to investigate the clinical and radiological outcome cervical laminoplasty for myelopathy degenerative spondylolisthesis. Summary background data presence spondylolisthesis is thought represent segmental instability in spine. Cervical a common decompression surgery myelopathy, but its result has not been well studied. Methods One hundred seventeen patients who underwent were included. Japanese Orthopaedic Association score (JOA score) visual analog scale neck pain, upper arm pain numbness evaluated before surgery, at scheduled time points after surgery. Spondylolisthesis defined as more than 2 mm slip on plain radiograph, results compared between (group S) without C). In spondylolisthesis, distance translational motion flexion extension examined lateral radiograph years Results Degenerative found 49 levels 33 (28.2%), average age group S significantly higher C. JOA each VAS improved both groups. Average lower C every points, recovery rate similar two level did changed, decreased 2years Conclusion elderly patients. comparable C, stabilized Thus, can be treatment option even Level evidence 3.
