In clinical practice, the examination of the cervical spine in the frontal and lateral position mainly refers to the taking of the cervical spine frontal and lateral radiographs. The frontal and lateral radiographs of the cervical spine are of great value in the diagnosis of cervical spondylosis because the morphology and curvature of the cervical spine, the narrowing of the intervertebral space, the presence of hyperplasia at the vertebral body margin, the site and size of the bony bulge, and whether the hook vertebral joint is compressing the nerve roots and the basilar artery can be observed from the frontal radiographs. Lateral radiographs can observe the alignment of the vertebral joints, the normal physiological curvature of the cervical spine, the site and degree of narrowing of the intervertebral space, paying particular attention to the bone flab at the posterior edge of the vertebral body, and also measure the anterior and posterior diameters of the spinal canal. If a patient is suspected of having cervical spondylosis, he or she should go to the hospital, and a clear diagnosis can be made by examining the hospital doctor and then taking a frontal and lateral X-ray of the cervical spine.
