Abstract:
Although radiological methods of measuring the sagittal diameter of the cervical spinal canal have recently been reported both at home and abroad, they are not quite satisfactory. In this article, based on the study of the radiological anatomy of the cervical spine, the author suggested that the sagittal diameter could be measured between the middle point of the linking line of the superior-inferior lips posterior to a vertebra and the laminal anterior cortical line.with a tube distance of 48 inches, standard lateral X-Ray films were taken in the neutral position of the cervical spines of 120 adults whom we have observed since 1979. They were divided into two groups: Group Ⅰ, sixty with normal cervical spines; Group Ⅱ, sixty with cervical syndrome. Using the above mentioned method, the sagittal diameters were measured of both groups. The normal diameters became physiologically reduced between C_3 and C_7 while in those with cervical syndrome, the diameters proved to be reduced at all levels; this tendency was especially apparent at C_(4-7). These findings demonstrated that cord compression may occur whenever the diameter is less than 14 millimeters. The diagnosis of cervical proliferation can be made through the findings in plain X-Ray films. Therefore, the sagittal diameter is the best guide for detecting stenosis resulted from cervical proliferation.
