Cervical spondylosis refers to the degenerative changes in the cervical disc and the secondary pathological changes that involve the nerve roots, spinal cord, vertebral artery, sympathetic nerve and other peripheral tissue structures with corresponding clinical symptoms. Degenerative changes in the cervical disc with age are the pathological basis of cervical spondylosis. Long-term ambulation, driving, cold in the neck, poor sleep posture, neck trauma and other factors can induce cervical spondylosis.
