Chest fracture belongs to serious injury or minor injury

A chest fracture is classified as a serious or minor injury depending on the severity of the fracture and the presence or absence of complications. A chest fracture is classified as a minor injury if it is a minor rib fracture with no apparent displacement, no apparent chest or pleural effusion, or breathing difficulties. A chest fracture is classified as a serious injury if it is accompanied by severe lung contusion, or breathing difficulties, and a large pleural effusion that causes subsequent traumatic cardiopulmonary disease.
