CCI & AAI
Craniocervical Instability (CCI) occurs when the cervical spine is unable to maintain its normal alignment. This can lead to deformity of the brainstem, uppers cervical spine, and cerebellum. Instability can lead to other conditions like Cranial Settling, where the skull starts to sink down onto the spine. It primarily occurs in conditions where the connective tissue is weak like Ehlers-Danlos.
​
Atlantoaxial Instability (AAI) occurs when there is excessive movement between at the junction between C1 (atlas) and C2 (axis). This also occurs frequently in conditions like Ehlers-Danlos.
