A randomized controlled study of two different fixations in anterior cervical discectomy of multilevel cervical spondylotic myelopathy

研究概要

Sixty patients with multilevel cervical spondylotic myelopathy (MCSM) were randomized to receive either anterior cervical discectomy and hybrid fusion with short-segment plate and self-locking stand-alone cages (n=30) or traditional anterior cervical discectomy and fusion with a long-segment plate (n=30). The Japanese Orthopaedic Association (JOA) was used to assess spinal cord nerve function and the Visual Analog Scale (VAS) for pain evaluation. Cervical curvature, postoperative dysphagia, and complications were also assessed. JOA, VAS, and curvature of the cervical spine showed better results over time in both groups. Significant differences in dysphagia were reported with a greater incidence in the control group at 1 week, 3 & 6 months.
