Case Discussion

The occipital condyle fracture represents a type 1 injury, which is a comminuted fracture with impaction and is generally considered a stable injury.

The transverse process fracture of the atlas represents a Gehweiler type 5 injury, which is limited to the transverse process and sparing the 'ring' of the vertebra.
