The occurrence of cervical spondylosis is related to a variety of factors, such as degeneration, strain, trauma, cervical spine developmental spinal stenosis, cervical spine congenital deformity, inflammation of the pharynx and so on. 1. Degenerative changes of the cervical spine: normal intervertebral discs maintain the height between vertebrae, absorb oscillations, and maintain the stress balance of cervical spine activities in all directions. If it begins to degenerate, the intrinsic balance of the bony structure of the cervical spine will be affected, and the mechanical balance of the surrounding tissues will be disrupted. Therefore, degeneration of cervical intervertebral discs is the main factor in the occurrence and development of cervical spondylosis. 2. Chronic strain: poor sleeping posture, poor working posture and daily habits, inappropriate physical exercise and other chronic strain will make the neck muscles and joints unevenly stressed, accelerating the degenerative process. 3. Head and neck trauma: strong violence caused by cervical trauma can often cause cervical vertebrae fracture and dislocation, and can be accompanied by spinal cord injury. 4. Developmental cervical spinal stenosis: The size of the sagittal diameter of the cervical spinal canal is directly related to the onset of cervical spondylosis. People with spinal stenosis are prone to spinal cord injury after trauma, and even minor trauma is easy to develop and have serious symptoms. 5. Congenital malformation of the cervical spine: localized malformation of the cervical spine can change the stress of the cervical spine, and may irritate and compress the neurovascular system, causing the occurrence of cervical spondylosis. 6. Inflammation in the throat: it can directly stimulate the neighboring muscles and ligaments, or spread the inflammation locally through the lymphatic system, resulting in the decrease of muscle tension, ligament laxity and imbalance of internal and external balance of the vertebral joints in the area, destroying its stability and thus promoting the development of degeneration.
