title: Computed tomogram myelography in cervical spondylosis.
abstract: Nine patients with severe and prolonged signs and symptoms due to cervical spondylosis had myelography followed by a CT Scan using the same injection of intrathecal contrast. All patients had radiographic changes of cervical spine degeneration and were being considered for exploration and fusion of the anterior cervical spine. All patients had a full clinical evaluation, EMG studies and plain radiographs taken prior to their CT Scan. EMG readings showed several levels of compression in three patients but did not indicate a single level in any. Plain radiography showed multiple level involvement in every patient. Myelography indicated significant indentation in three of five patients with clinical signs but did not demonstrate root cut off in any case. CT Myelography indicated the degree of Lushka and facet joint involvement, indentation, exit foramen encroachment, and the degree of spinal stenosis at the involved segment. In three patients, the findings at operation correlated closely with the CT Scans. Myelography failed to indicate the presence of significant osteophytes in these two cases.
