Atlantooccipital dissociation

Case contributed by A.Prof Frank Gaillard


Child presenting following a motor vehicle accident.


Cervical spine

Note the marked widening of the atlanto-occipital joint, consistent with atlantooccipital disassociation. No fractures identified. 

Case Discussion

Atlanto-occipital disassociation is usually seen in children and can be subtle on plain films, especially if one is only looking for fractures or disruption of the normal longitudinal lines.
