Cervical spondylosis is a condition in which there is a progressive degeneration of the disc leading to characteristic changes in the surrounding structures, especially bones and nerves. Plain radiograph for detecting of these characteristic changes have been limited because the patients of the cervical spondylosis has distorted alignment and the shadow of superimposed structures. Then tomograph is frequently useful in delineating the accurate evaluation of the cervical spine. It is necessary to demonstrate the isolated anatomical section cope with lordosis, distorted alignment at the single tomographic plane. Various technical problems such as determination of precise tomographic plane, safe and satisfactory immobilization, proper centering of the beam are not yet resolved. The authors describe the new attempt of tomographic technic for cervical spondylosis.
