How can you break your sternum?

The sternum can be broken through direct trauma, such as a severe impact from a car accident, a fall onto the chest, or during CPR if excessive force is applied. It can also fracture from sports injuries, particularly in contact sports. Additionally, certain medical conditions that weaken bones, like osteoporosis, can make the sternum more susceptible to fractures with less force. Always seek medical attention if you suspect a sternum injury.
