Cervical spondylosis is also known clinically as cervical spine syndrome, cervical proliferative arthritis, cervical degenerative arthritis, and neck and shoulder syndrome. It is a slowly progressive degenerative disease that commonly occurs in middle-aged and elderly people. Its onset is due to degeneration or protrusion of cervical discs, narrowing of the cervical spinal space, loosening of the joint capsule, imbalance of internal balance and formation of progressive bone redundancy, which stimulate or compress the adjacent cervical spinal nerve roots, cervical spinal cord, vertebral artery, anterior spinal artery and cervical sympathetic nerve respectively, resulting in a complex syndrome with a wide range of symptoms and effects.
