A broken rib, or fractured rib, is a common injury that occurs when one of the bones in your rib cage breaks or cracks. The most common cause of broken ribs is trauma to the chest, such as from a fall, motor vehicle accident or impact during contact sports.
Many broken ribs are merely cracked. While still painful, cracked ribs aren't as potentially dangerous as ribs that have been broken into separate pieces. A jagged edge of broken bone can damage major blood vessels or internal organs, such as the lungs.
In most cases, broken ribs usually heal on their own in one or two months. Adequate pain control is important so that you can continue to breathe deeply and avoid lung complications, such as pneumonia.
