    B. Kidney injury
    The patient has a positive seatbelt sign, or ecchymosis on the lower abdomen from a lap belt. An MVA with a sudden stop results in a hyperflexion injury mechanism, and the lap belt can cause injury particularly when it is worn too high and exerts pressure on the abdominal contents. Common injuries from this mechanism are hollow viscus (small bowel in particular) injury, Chance fracture (horizontal vertebral body fracture) of the spine, and sometimes associated spinal cord injury. The kidneys are retroperitoneal and less likely to be injured by a hyperflexion mechanism.
