There are bilateral jumped facets at C6 with fracture of the bilateral C6 lamina and grade 4 anterolisthesis of C6, which is completely in front of and overlapping C7. The spinous process of C5 overlaps the lamina of C6. There are comminuted fractures of the bilateral facets at C6 and C7. There are chip fractures of the anterior aspect of C7.
There is prevertebral swelling centered at the C6-C7 level. There is an acute angulation of the spinal canal at C6-C7. There is an additional oblique fracture through the left aspect of the C6 vertebral body. There is an acute minimally displaced fracture of the right transverse process of C4, C6, and C7. The fracture of C6 involves the transverse foramen.
On the CTA portion of the exam, the vertebral arteries enhance well including the region of injury noted without evidence of dissection or extravasation at the time of the scan. There is no evidence of dissection of the carotid arteries.
