The cervical spine connects the head and the thoracic spine and is the most flexible and most frequently active segment of the spine, and it also bears the weight of the head. Cervical spondylosis is a clinical syndrome caused by cervical disc degeneration itself and its secondary changes that compress or stimulate adjacent tissues such as nerve roots, spinal cord, vertebral artery, esophagus, etc. From the definition of the disease, we can see that its pathogenesis is caused by degenerative changes of the cervical intervertebral disc, and the degeneration of the disc is the primary change of cervical spondylosis. The degeneration of the intervertebral disc can be significantly accelerated and a series of secondary changes can be produced on the basis of the primary degeneration of the cervical spine. Cervical spondylosis belongs to the category of degenerative diseases, but cervical spondylosis cannot be simply equated with cervical spine degeneration. Some patients have significant degeneration on imaging, but clinical symptoms and signs are not obvious, while others have mild to moderate degeneration on imaging but cause severe symptoms and signs, so clinical symptoms, signs and pathological changes must be combined to diagnose cervical spondylosis. Cervical spondylosis is a common and frequent disease in clinical practice, and if treatment is delayed it can cause irreversible nerve damage or even endanger life, seriously endangering the physical and mental health of the general public.
