Which statement describes a Jefferson fracture?

Explanation:
The Jefferson fracture is a burst fracture of the atlas (C1). It results from axial loading that causes the ring-shaped atlas to fracture in multiple places, typically with outward (lateral) displacement of the lateral masses. This pattern is specific to C1 and distinguishes it from injuries like a dens (odontoid) fracture or a fracture of the posterior arch of C1, as well as from a burst fracture of C2. So the statement describing a burst fracture of C1 best captures what a Jefferson fracture is.
