The authors report a study of 47 patients admitted for cervical myelopathy (N = 17) or symptomatic lumbar spinal stenosis (N = 30). Nine patients had clinical evidence of coexisting cervical myelopathy and lumbar spinal stenosis. Ten out of the 17 patients having cervical myelopathy had lumbar spinal stenosis as evidenced by sagittal tomography and/or computerized tomography. Nine out of the 30 patients admitted for symptomatic lumbar spinal stenosis had coexisting cervical canal stenosis as evidenced by sagittal tomography. Thirteen out of these 19 patients with both cervical and lumbar canal stenosis had also ankylosing spinal hyperostosis.
