Anterior longitudinal ligament ossification

Clinically, there are far more ossifications of the anterior longitudinal ligament than those of the posterior longitudinal ligament. About 80% of the cervical spine X-rays can show this feature. It accounts for half, and the incidence of thoracic vertebrae is the lowest. But the real symptoms (mostly neck discomfort mainly, some may have signs of esophageal compression, and those that occur in the chest and lumbar spine, rarely cause symptoms), only 0.1% to 0.3%, so generally not People value it.
