Study Design:Retrospective analysis of prospectively collected observational data.Objective:This study aimed to evaluate the slippage, sagittal alignment, and range of motion (ROM) after selective laminectomy (SL) in patients who had cervical spondylotic myelopathy (CSM) with degenerative spondylolisthesis (DS).Summary of Background Data:Clinical outcomes have been reported for both decompression and fusion surgeries for DS of the lumbar spine. However, only a few reports have examined cervical spine spondylolisthesis.Materials and Methods:This study included 178 patients who underwent SL for CSM. Those with ossification of the posterior longitudinal ligament were excluded. Slippage> 2 mm was defined as spondylolisthesis, and spondylolisthesis progression was defined as an additional displacement> 2 mm on a neutral radiograph. The slippage, translational motion, C2–C7 angle, local kyphosis, and ROM were examined before and≥ 2 years after surgery. Radiologic parameters were evaluated according to the slip direction and the number of laminae removed.Results:DS was observed in 29 patients (16.3%); 24 patients, comprising 9 and 15 in the anterolisthesis and retrolisthesis groups, respectively, were successfully followed up for more than 2 years. Preoperative and postoperative radiologic changes in slippage, translational motion, C2–C7 angle, local kyphosis, and ROM were not remarkable in either group regardless of the number of laminae removed. Revision surgery for the progression of DS and alignment deterioration was not required in any patient of either group.Conclusions:SL does not affect DS, sagittal alignment, or ROM irrespective of the slip direction and the number of laminae removed, even after> 2 years after surgery. Given the preservation of the posterior elements, SL may be an effective treatment for CSM with DS.Level of Evidence:Level IV.Cervical spondylotic myelopathy (CSM) may result from spinal cord compression caused by various pathologies, such as the hypertrophy of the ligamentum flavum, disc degeneration, and arthrosis of the facet joints. Furthermore, cervical degenerative spondylolisthesis (DS) is an important factor that causes CSM because the sagittal diameter of the osseous spinal canal is reduced. 1, 2 Studies report the overall prevalence of cervical DS to range between 5.2% and 11%, 3, 4 and it is observed in 18.9% of symptomatic patients. 5
