The cervical vertebrae click, usually due to two reasons: 1, due to cervical spine degeneration, resulting in the cervical spine joint synapse joint position joint surface becomes uneven, or local hyperplasia and calcification, in the cervical spine activities, the hyperplasia and degeneration of the joint surface extrusion, friction, so will appear cervical spine click, in the clinical also called popping sound. 2, due to the cervical spine part of the cold or excessive fatigue after the formation of strain injury The local soft tissues such as ligaments are tense and contracted, and when cervical spine activities are carried out, the ligaments and the surrounding bony structures are rubbed and squeezed, and the cervical spine area is prone to clicking. Patients should take relevant protective measures for the cervical spine, avoid prolonged head down, pay attention to warmth and not to get cold, otherwise it will lead to further accelerated degeneration of the synovial joint, and the surrounding soft tissues and ligaments will become more tense, and further hyperplasia and calcification may occur over time.
