There is a comminuted avulsed fracture involving the right occipital condyle with medial fragment displacement (alar ligament avulsed fracture), which does not cause significant stenosis of the foramen magnum but mildly pushes against the V3/V4 transition of the right vertebral artery. Both vertebral arteries demonstrate normal flow-void though.
Compression fracture causing anterior wedging of the C7 vertebral body with height loss in about 20% but no associated retropulsion. There is disruption of the flavum ligament at C6/7. Increased signal suggesting avulsion of the nuchal ligament from its insertion on the C7 spinous process and a mildly increased signal of the C6/7 interspinous ligament suggesting some distraction. The anterior longitudinal ligament appears redundant at the level of C6/7 with no tear identified; some oedema is noted in the prevertebral soft tissues at this level. The remainder of the vertebral bodies has normal height, bone marrow signal, and alignment. The cord is normal in the signal. The canal and neural exit foramina are capacious, with no high-grade stenosis. Limited views of the posterior fossa are unremarkable.
