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, which is a disorder based on degenerative pathological changes. It is a clinical syndrome with a series of dysfunctions 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. It manifests as a series of pathological changes of cervical disc degeneration itself and its secondary pathology, such as destabilization and loosening of vertebral joints; herniated or prolapsed nucleus pulposus; bone spur formation; ligamentous hypertrophy and secondary spinal stenosis, etc., which stimulate or compress the adjacent nerve roots, spinal cord, vertebral artery and cervical sympathetic nerve and other tissues, causing a series of symptoms and signs. Cervical spondylosis can be divided into: cervical cervical spondylosis, nerve root cervical spondylosis, spinal cord cervical spondylosis, vertebral artery cervical spondylosis, sympathetic nerve cervical spondylosis, and esophageal compression cervical spondylosis.
