Cervical spine X-rays can be used not only to diagnose cervical spondylosis, but more importantly, to exclude many other neck diseases. Such as ossification of the posterior longitudinal ligament of the cervical spine, rheumatoid arthritis, osteoarticular tuberculosis, congenital deformity of the cervical spine, fracture and dislocation, and tumor. Generally, frontal, lateral and double oblique films of the cervical spine can be taken. Lateral radiographs can observe microscopic changes in vertebral body arrangement, articular prominence, joint position and displacement of spinous processes, etc. In particular, the anterior and posterior diameters of the spinal canal can be measured more accurately, and changes in the physiological curvature of the cervical spine can be observed. The orthopantomogram can show the bilateral hook vertebral joints and their gaps, and can observe whether the width of the vertebral plates is symmetrical and whether there is movement of the spinous processes on both sides. In the cervical 1 to 2 open position, the morphology of the dentate process of the pivot spine and its abnormal changes can be observed. When the cervical spine is rotated and displaced, the upper articular processes of the affected vertebrae can be seen to be displaced forward and upward, making the transverse diameter of the intervertebral foramen smaller.
