Images from a CT angiogram of the head and neck.
There is an acute fracture-dislocation at C7-T1 with grade 3 traumatic anterolisthesis of C7 over T1 and dislocation of the facet joints at that level bilaterally, compatible with locked facets. Anterior wedge fracture of T1 is noted with 15-20% loss of vertebral body height. A small avulsed bone fragment is also seen rising from anterosuperior corner of T1. There is associated moderate to severe narrowing of the central canal at C7-T1 with likely spinal cord compression.
