Atlanto occipital dissociation disrupts the ligaments joining the skull to the cervical spine. This usually involves disruption of the alar ligaments, apical ligaments, and joint capsules. The bone displacement can occur between the occiput in C1 or between C1 and C2, with C1 remaining attached to the skull and displacing with the occipital condyles.
