Hangman's fracture results in separation of the C2 vertebral body and posterior arch, generally via a coronally oriented fracture through the posterior C2 body and/ or pedicles. This injury is very rare in younger children, but occurs in adolescents. A fracture with little displacement or angulation generally causes no neurological deficits and heals well with external orthosis alone. Displaced and angulated fractures may present with devastating neurological deficits and often require operative fusion.
