Abstract

Traumatic atlanto-occipital dislocation (AOD) refers to severe instability at the atlanto-occipital (AO) joints due to traumatic disruption of the osseo-ligamentous structures, in which neurological damage is present or imminent if left untreated. AOD represents the most severe form of cervical injuries, but the bony displacements at the AO joints may be inconspicuous on routine radiology, somewhat incongruous with what the term dislocation implies. Other terms such as atlanto-occipital dissociation (Cooper et al. 2010), atlanto-occipital distraction (Bani and Gilsbach 2003), atlanto-cranial dislocation, and craniocervical dislocation (Bellabarba et al. 2006) have been used. Sometimes, qualifiers such as complete or partial AOD are added (Grabb et al. 1999; Shamoun et al. 1999; Horn et al. 2007).
