Atlantoaxial joint instability can be treated with traction therapy, surgery and daily care according to the severity of the condition. 1. Traction therapy: Atlantoaxial joint instability can be caused by prolonged bad posture, trauma and other factors. If the symptoms are mild and in subluxation, it is usually treated with occipitomandibular traction, and it can also be fixed with a brace, which can help atlantoaxial joints to be reset through periarticular traction and ligament tension. 2. Surgical treatment: when the atlantoaxial joint is completely dislocated, it will be compressed by the medulla oblongata and high cervical medulla, which may lead to quadriplegia or even respiratory failure in severe cases. Therefore, surgical treatment, such as atlantoaxial joint release surgery, is needed to avoid the condition getting worse. 3. Daily care: daily attention should be paid to protecting the posture of cervical vertebrae, avoiding prolonged bowing of the head, ambulation and other actions, and paying attention to local warmth. During the treatment period, repeated rotation of the neck should be avoided, and bending activities should be avoided to avoid affecting the therapeutic effect. Attention should be paid to the selection of appropriate pillows, should not be too high and too hard. Patients with atlantoaxial joint instability are advised to seek early medical treatment and standardize the treatment under the guidance of doctors to avoid delaying the condition.
