In one study of patients with rib fractures, the mortality rate reached 12%; of these, 94% had associated injuries and 32% had a hemothorax or a pneumothorax.[5] More than half of all patients required either operative or ICU management. Average blood loss per fractured rib is reportedly 100-150 mL.
