The degree of your sternal fracture, how the bone shattered, and the specific symptoms you're experiencing will all influence how you're treated. Resting and allowing the break to heal is the most usual type of therapy. During this period, apply ice to the chest to reduce swelling and soreness. A belt or corset may be used to support the chest while it heals. If you have other injuries as a result of your crash, such as head trauma, internal bleeding, etc., those patients should also be treated by a medical professional immediately after the accident. They will be able to assess the extent of your injuries and make the best treatment decisions for you based on what they find. Sternal fractures are usually diagnosed using radiographs (x-rays). The doctor may also perform an ultrasound exam or order blood tests to determine if there's any underlying injury that needs attention before moving forward with fixing your chest wall. There are several different methods used to repair a fractured sternum, depending on the severity of the injury and your body size. If the bones are separated but still attached in the middle, they can be put back together with metal plates and screws. This is called a open procedure and it requires cutting out portions of the ribcage to get at the chest cavity and insert surgical instruments between the bones to place the plates and screws.
