1. What is cervical spine disease? The cervical spine is located between the head and the thorax and is the segment of the spine with the smallest volume, the greatest flexibility and the highest frequency of activity. After birth, as the body develops and grows, the cervical spine is able to adopt different postures and perform various activities to adapt to its function of supporting and moving the head. Degenerative changes gradually occur due to constant exposure to various loads, strain and even minor trauma. The cervical intervertebral disc degeneration is the earliest and induces or promotes degeneration of other tissues of the cervical spine, which becomes the basis for the occurrence and development of cervical spondylosis. Cervical spondylosis is called cervical spondylosis when the degenerative changes of the cervical disc tissue and its secondary pathological changes involve the surrounding tissue structures (nerve roots, spinal cord, vertebral artery, etc.) and the corresponding clinical manifestations occur. The three typical features of cervical spondylosis in imaging are disc degeneration, bone redundancy and thickened ligaments. 2.What are the causes of cervical spondylosis? (1) Strain injury is an important cause of the development of cervical spondylosis. (2) Developmental cervical spinal stenosis is very closely related to the occurrence and development of cervical spondylosis. (3) Trauma to the head and neck is directly related to the onset and development of cervical spondylosis. (4) Congenital malformation of the cervical spine is also associated with the occurrence of cervical spondylosis. (5) In addition, some scholars believe that some patients are also associated with genetic predisposition.
