The age of onset of the disease ranges from 25 to 56 years old. There are more males than females, and the incidence rate is 1/10 of lumbar disc herniation. Due to the different locations of disc herniation in the intervertebral canal, clinically it can be divided into lateral herniation type, paracentral herniation type and central herniation type. From the etiological point of view, the lower cervical vertebrae are more weight-bearing, frequently active, and connected with the more fixed thoracic vertebrae, so they are most prone to strain and degeneration. Degeneration occurs after the first is composed of the fibers in the fibrous ring of the disc becomes thick, and then glass-like degeneration occurs, so that the final fracture, so that the disc loses its original elasticity, can not bear the original pressure. Whenever subjected to the role of cranial gravity, muscle pulling and trauma and other factors, the annulus fibrosus can be outwardly bulging, so that the nucleus pulposus can also be ruptured through the fissure of the annulus fibrosus protruding outward. This is called a herniated disc. Due to the leverage effect, the force below the 5th cervical vertebrae is the greatest, and the chances of injury are relatively higher. Therefore, cervical disc herniation occurs mostly in cervical 6-7 or cervical 5-6.
