o Craniocervical junction (CCJ) injuries carry significant morbidity and mortality. o The normal bony, ligamentous and vascular anatomy of the CCJ o Examples of subtle and major osseous, ligamentous and vascular traumatic injuries to this region

CCJ injuries are common traumatic injuries of the skull base and cervical spine. Mechanisms may include hyperextension, hyperflexion, distraction and axial load injuries. The unique anatomy and biomechanics of the craniocervical junction give risk to characteristic injury patterns, which may be subtle to detect. This educational exhibit explains normal bony, ligamentous and vascular anatomy of the craniocervical junction. All CCJ injuries at our level I trauma center over the last 5 years were reviewed.  Here we provide a method of assessment for the region, and highlight features not to be missed. We describe classification with relevance to further management. CT/MR imaging examples will include: · Osseous and ligamentous injuries: occipital condyle, atlas and axis fracture patterns and instability, C2-3 facetal injuries, as well as atlanto-occipital disassociation, and distraction injuries. · Non-osseous, non-ligamentous vascular injuries including transection, dissection, AV fistulae and pseudoaneurysms.
