The breast bone, also known as the sternum, is a long, flat bone located in the middle of the chest region of the human body. The breast bone is connected to the ribs by a flexible type of connective tissue called cartilage. The primary role of the breast bone is to protect the heart and lungs from any type of physical trauma. While a fracture of the sternum is not a common injury, it does sometimes happen. When this occurs, prompt medical attention is necessary to gauge the extent of the damage and begin appropriate treatment.

During certain types of thoracic surgery, or surgery relating to the organs found in the chest area of the body, it may be necessary for the surgeon to cut open the breast bone in order to reach the organs. This type of surgery is called cardiothoracic surgery, with the actual process of cutting open the sternum referred to as a median sternotomy.

When a traumatic injury such as a car accident or sports injury results in a direct blow to the chest, it is possible for the breast bone to become fractured. If this type of injury is suspected, an immediate trip to the hospital is in order. Typically, x-rays will be ordered right away to verify the presence of a fracture. Since the sternum works to protect the vital organs found in the chest, tests will often be ordered to make sure there is no damage to the heart or lungs.

Once a fracture has been confirmed and it has been determined that the breast bone did its job by protecting the organs of the chest, a treatment plan can be devised. Pain medications such as ibuprofen are often prescribed in order to help reduce the amount of swelling and inflammation as well as provide some level of pain relief. Doctors once bandaged the fractured sternum tightly in order to reduce movement while healing. However, this is no longer common practice, as it is believed that the breast bone heals more quickly and completely if left unhindered, allowing more room for efficient breathing.

The patient should rest as much as possible during the first two weeks following a breast bone injury. Afterward, activity may be slowly increased as long as the patient does not experience excruciating pain. It typically takes the body several weeks to heal completely from this type of injury, so it is important to not try to resume normal activity levels before the body is ready.
