To determine the specific cause of atlantoaxial joint asymmetry, if the joint dislocation is caused by external force injury, it should be more serious because further external force injury in this state will easily lead to further aggravation of the joint dislocation, resulting in compression of the spinal cord behind the cervical spine and easy paralysis symptoms. If there is no obvious external injury, it is the result of cervical spine strain and strain over time, which is a manifestation of cervical spondylosis, the main clinical symptom is dizziness, not particularly serious, but also should be treated systematically, through cervical acupuncture, massage, small acupuncture treatment effect are very good. Usually pay attention to cervical spine maintenance, avoid long time low head ambulation work, work in front of the computer. If the joint asymmetry is caused by trauma, serious cases should be corrected by internal fixation through surgery.
