Chance Fracture in an Unbelted Rear Seat Passenger.

Chance fracture occurs from flexion-distraction injury in motor vehicle road crash usually when the patient is on a seat belt. It is often associated with intra-abdominal injuries. We managed a 22-year old female unbelted rear seat passenger of a bus which was involved in a lone accident. We highlighted the possible mechanism of chance fracture in an unbelted passenger and satisfactory spinal stability on conservative care with neither internal nor external fixation.
