This document discusses thoracic trauma, specifically rib fractures and haemothorax. It begins by defining chest trauma and classifying injuries as blunt or penetrating. Rib fractures are then described in more detail, noting that the middle ribs are most commonly fractured from direct blows or crushing injuries. Symptoms of rib fractures include pain with breathing or movement. Haemothorax is defined as blood accumulating in the pleural cavity, usually from a blunt or penetrating chest injury causing a rupture. Management of haemothorax involves draining existing blood and removing the bleeding source by inserting a chest tube.
