Incidence of Cervical Stenosis: Radiographic and Anatomic

Cervical canal size and shape can play a role in the development of myelopathy and/or radiculopathy. Small canal diameters have been associated with increased neurologic dysfunction for a variety of conditions. Various radiographic criteria have been used to better define sagittal canal dimensions, with variable degrees of accuracy. In addition, some patients with radiographic stenosis may be asymptomatic, thus making the significance of radiographic stenosis less clear.
