Cervical spondylosis is a slowly developing degenerative disease commonly found in middle-aged and elderly people. Its onset is due to degeneration or protrusion of cervical intervertebral discs, narrowing of the cervical spinal space, disturbance of internal balance and progressive bone formation, which stimulate or compress the adjacent cervical spinal nerve roots, cervical spinal cord, vertebral artery, anterior spinal artery and cervical sympathetic nerve and other tissues respectively, resulting in a syndrome with a wide range of symptoms and effects. Generally speaking, if the symptoms are mild, non-surgical treatment can be taken, while paying attention to observation. If the body below the neck is paralyzed, with varying degrees of sensory and motor disorders, and constantly aggravated or suddenly intensified, surgery must be performed as soon as possible, otherwise it will be difficult to recover if the time drags on and the compressed nerve degenerates.
