Cervical spondylosis has a high incidence, and the groups at risk are as follows: 1, middle-aged and elderly people With the growth of age, excessive chronic strain on the cervical spine can cause a series of degenerative pathological changes such as deformation of the intervertebral disc, weakening of elasticity, formation of bone spurs at the vertebral body edge, disorder of small joints, thickening of ligaments, calcification, etc. Therefore, there are more middle-aged and elderly people suffering from cervical spondylosis. 2, improper work posture Some occupations such as: office workers, computer operators, text workers, teachers, accountants, scientific researchers, typists, drivers, athletes, laboratory analysts, heavy manual laborers, etc., due to long-term fixed posture work, so that the neck extensor muscle has been in a state of spasm, over time, so that the balance of the neck flexor and extensor muscle imbalance, and then lead to spinal imbalance, and eventually lead to cervical spondylosis. 3, poor sleep position people have 1/3 of their lives spent in bed, the height of the pillow to scientific and reasonable. The pillow is high will cause the neck muscles, ligaments and small joints to be out of balance, accelerating the degeneration of the cervical spine. 4, bad habits long time low head playing mahjong, playing poker, watching TV, reading newspapers, these bad habits make the cervical spine in a state of flexion for a long time, the back of the neck muscle and ligament tissue overload, easy to cause strain injury. 5, a history of trauma and congenital deformity of the cervical spine A history of trauma leading to cervical spine injury, suffering from congenital deformity of the cervical spine, belongs to the high incidence of cervical spondylosis.
