A 63-year-old man who had experienced numbness in both hands and felt stepping on cotton in lower limbs for 3 years was diagnosed as cervical spondylotic myelopathy. A Preoperative cervical lateral X-ray plain radiograph showed the alignment of cervical spine was straight and osteophyte emerged at the anterior edge of the vertebral body. B, D, E, F Cross-sectional and sagittal T2-weighted MRI showed degenerative disc protrusion and spinal cord compression at C4–C5, C5–C6, and C6–C7, respectively. C Sagittal CT reconstruction showed that osteophyte compression was found at C5–6 level. The patient underwent three-level ACDF with anterior cage-with-plate. G The X-ray examination showed that the alignment of cervical spine improved significantly two days postoperatively. H X-ray film which was taken five months postoperatively identified that the alignment of cervical spine was well maintained, and the positions of cages were good. I At fourteen-month follow-up, the lordosis of the cervical spine and the positions of cages were still remained
