Subtotal vertebrectomy and spinal fusion for cervical spondylotic myelopathy

To perform decompression of the spinal cord and stabilization of the cervical spine in the patients with cervical spondylotic myelopathy, subtotal vertebrectomy and spinal fusion of the cervical spine were carried out in 30 patients. In 18 patients, three vertebrectomies and a spinal fusion were carried out, and in 12 patients, four vertebrectomies and a spinal fusion were carried out. Neurologic symptoms that were present before the operations ranged from transverse lesion type myelopathy to motor system syndrome. The patients' symptoms improved significantly after the operations. By the final consultation, the cervical spine motion reduced by about half in the four level vertebrectomy patients and about one third in the three level vertebrectomy patients. No patients reported cervical pain or pain in the arms.
