It is currently believed that the fundamental cause of cervical spondylosis is due to degenerative changes in the cervical spine caused by aging, poor life postures, and work habits. These degenerative changes lead to instability between the vertebrae, resulting in cervical disc herniation or localized bone hyperplasia. The herniated discs and bone growth compress nearby nerve roots, the spinal cord, and vertebral arteries, causing symptoms of compression in these structures and leading to cervical spondylosis. There are also some factors that trigger cervical spondylosis, with common ones being exposure to cold, excessive fatigue, and poor lifestyle and work habits. Paying attention to these factors can generally prevent the onset of cervical spondylosis.
