Cervical spondylosis, also known as cervical spine syndrome, is a general term for cervical osteoarthritis, proliferative cervicitis, cervical nerve root syndrome, and cervical disc prolapse; it is a disorder based on degenerative pathological changes. It is a clinical syndrome mainly due to long-term cervical spine strain, osteophytes, or disc prolapse and ligament thickening, resulting in compression of the cervical spinal cord, nerve roots or vertebral artery, leading to a series of functional disorders. The cervical disc degeneration itself and its secondary series of pathological changes, such as destabilization and loosening of the vertebral joint; herniated or prolapsed nucleus pulposus; bone spur formation; ligamentous hypertrophy and secondary spinal stenosis, etc., stimulate or compress the adjacent nerve roots, spinal cord, vertebral artery and cervical sympathetic nerve and other tissues, and cause a variety of symptoms and signs of the syndrome.
