From 1979 through 1986, eleven patients with multisegmental cervical spondylotic myelopathy were treated with subtotal verterectomy and spinal fusion at our hospital. In 7 patients, two verterectomy and spinal fusion were carried out, and 4 patients, three verterectomy and spinal fusion were carried out.The patients were evaluated by The Japanese Orthopedic Association (JOA) score. The preoperative score ranged from five to twelve points with the mean being 8.8. The postoperative score ranged from ten to seventeen points with the mean being 13.6. Ten patients showed improvement after operation and was satisfied with the result of operation.In the present study some radiological findings of the degeneration in the adjacent vertebral segments, reduction of the cervical spine motion, and high rate of pseudoarthrosis of the grafted bone were observed. However, such findings were not so serious as a recurrence of myelopathy would occur. Thus, even for cases with multiplelevel involvement, this procedure has provided excellent results.
