Guo S, Lu, SM, et al. - A nonrandomized and prospective study was performed to correlate clinical outcomes and sagittal alignment after one-level, two-level, and three-level anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylotic myelopathy. This retrospective study included a sum of 175 patients with cervical spondylotic myelopathy who had undergone ACDF. Researchers conducted a neurofunctional assessment with the Japanese Orthopedic Association (JOA) score and the recovery rate of the JOA score. This study’s findings demonstrated that ACDF with different levels had similar postoperative clinical outcomes. The results demonstrated that three-level ACDF has an apparent advantage in restoring lordosis, a poor ability to maintain lordosis, and a higher incidence of complications in comparison with one-level or two-level ACDF.
