What are Common Chest Injuries? Rib Fracture: A broken rib, or fractured rib, is commonly caused by a motor vehicle accident. A rib break or fracture can be potentially dangerous if the bone damages any surrounding organs or blood vessels. Laceration: Any cut that tears the skin is referred to as a laceration. It is unlike an abrasion where the skin is scraped because the skin is not missing just separated. In a car crash, there are many factors that could cause lacerations to a person- glass, metal, objects within the vehicle itself. Pneumothorax: This is the medical term for a collapsed lung. When air collects in the space around the lungs, the lung suffers pressure and it cannot expand the way it needs to provide proper breathing.
