Upper cervical spine instability

The cervical spine itself contains many instability factors from birth, especially the horizontal position of the intervertebral joints, the relaxation of ligaments, and the ratio of the spinal cord to the spinal canal. Cervical vertebral segment instability is not only a process in the pathophysiology of cervical spondylosis, but also can be an independent disease when the duration is too long. Upper cervical spine instability mainly includes occipital-cervical instability and atlanto-axial joint instability. The former are more common in trauma and occipital neck deformities, and the condition is more serious. In addition to the latter, which is related to neck trauma, it usually occurs after inflammation of the posterior wall of the throat in children. This is due to the relaxation of the local ligament of the atlantoaxial joint. In terms of treatment, it is relatively easy to treat early cases and the prognosis is also Many are better, but in advanced cases, or due to trauma or congenital malformations, the condition is more complicated, and the prognosis is also large. The main difficulty of the disease is the knowledge of the disease and the early diagnosis and timely treatment based on it.
