The cervical spine is between the head, which is frequently active and heavily weighted, and the thoracic spine, which is lacking in activity and relatively stable, and is relatively weak anatomically, lacking other bony protection around, and vulnerable to direct blows from external forces, especially the lower cervical spine and its surrounding soft tissues are prone to strain lesions. 1, strain injury: long-term so that the head and neck in a single posture position, such as prolonged low head work, prone to cervical spondylosis. Cervical spine patients younger than 30 years old are mostly engaged in low-headed work. 2, head and neck trauma: 50% of medullary cervical spondylosis is related to neck trauma. Some patients with cervical spine osteophytes, cervical disc bulge, soft tissue lesions in the spinal canal, etc. make the cervical spinal canal in a narrow critical state, cervical trauma often triggers the symptoms. 3, bad posture: such as lying in bed watching TV, reading books, high pillow, sleeping in a sitting position, etc.; sleeping in a recumbent car, poor muscle protection when sleeping, easy to neck injury when braking. 4, chronic infection: mainly pharyngitis, followed by dental caries, periodontitis, otitis media, etc.. Inflammation in these areas stimulates the soft tissues of the neck or causes soft tissue lesions in the neck and occipital area through the rich lymphatic system. It is believed that chronic pharyngeal infection is an important factor in the pathogenesis of cervical spondylosis, which may be aggravated by the interaction of soft tissue chronic strain inflammation. 5, wind, cold and wet factors: wind, cold and wet factors in the external environment can reduce the body’s tolerance to pain, which can cause muscle spasm, small blood vessel constriction, slow lymphatic flow, soft tissue blood circulation disorders, followed by aseptic inflammation. Therefore, wind, cold and damp factors are not only causative factors, but also can be used as a cause to cause lesions to produce symptoms. 6, cervical spine structure dysplasia: congenital small spinal canal, cervical degeneration, etc. is the basis for the pathogenesis of some cervical spondylosis. Foreign statistics 40-50 years old with degeneration accounted for 25%, more than 55 years old with degeneration accounted for 85.5%. The incidence of cervical spondylosis is one times higher than normal in people with narrow central cervical spinal canal and nerve root canal.
