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, ligament thickening, or even after trauma, 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 effects, such as destabilization, loosening, nucleus pulposus protrusion or prolapse, 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.
