Atlanto-occipital instability is a condition in which the joint between the base of the skull (the occiput) and the first cervical vertebra (the atlas) moves more...
Anterior atlanto-occipital displacement—often called anterior atlanto-occipital dislocation—is a severe instability at the craniocervical junction in which the skull shifts forward relative to the first cervical vertebra...
Degenerative instability of the atlanto-occipital (AO) joint refers to excessive movement at the junction between the skull’s occipital condyles and the first cervical vertebra (the atlas,...
Atlanto-occipital joint inflammatory instability occurs when inflammation weakens or destroys the ligaments and joint surfaces between the atlas (C1) and the occiput (base of the skull),...
The atlanto-occipital joint is a condyloid synovial articulation between the occipital condyles at the base of the skull and the superior articular facets of the atlas...
The atlanto-occipital (AO) joints are the paired synovial articulations between the occipital condyles of the skull and the superior facets of the first cervical vertebra (the...
Atlanto-occipital lateral displacement is a severe form of craniocervical injury in which the occipital condyles—the rounded protrusions at the base of the skull—shift sideways relative to...
