Sternum

Sternum or breastbone is a long, flat bone located in the center of the thorax (chest). It connects to the rib bones via cartilage, forming the rib cage with them, and thus helps to protect the lungs and heart from physical trauma.

Fractures of the Sternum

Fractures of the sternum are not common, however, they may result from trauma such as when a driver's chest is forced into the steering column in an accident. A fracture of the sternum is usually a comminuted fracture, meaning it is broken into pieces. The most common site of sternal fractures is at the sternal angle.
