The sternum, or breastbone, is a flat bone in the center of the chest. It plays a crucial role in protecting vital organs such as the heart and lungs. Due to its position, the sternum is vulnerable to injuries from direct impact or pressure. When a strong force is applied to the chest, it can result in a sternum fracture, causing significant pain and discomfort.
Car accidents are a major cause of chest injuries, and the most common cause of sternum fractures is high-impact trauma, such as a sudden collision. When a vehicle stops suddenly, the force can push the chest against the steering wheel or seatbelt, leading to a fracture. This type of injury requires immediate medical attention to prevent complications and ensure proper healing.
What Is a Fractured Sternum?
A fractured sternum occurs when the breastbone cracks or breaks due to a strong force. This type of injury can be painful and limit movement. According to the National Institutes of Health (NIH), sternum fractures account for about 3–6.8% of blunt chest trauma cases, most of which result from vehicle collisions. The severity of the fracture depends on the force of impact and whether the injury involves additional complications, such as damage to nearby organs. Recovery time can range from a few weeks to several months.
Symptoms of a Fractured Sternum
There are numerous symptoms associated with a fractured sternum, and some of them include:
- Sharp Chest Pain: Pain that worsens with movement, deep breathing, or coughing.
- Swelling and Tenderness: The area around the fracture may become swollen and sensitive to touch.
- Bruising: Discoloration of the skin may appear due to internal bleeding.
- Difficulty Breathing: Pain may make it hard to take deep breaths.
- Cracking Sensation: Some people may feel or hear a cracking sound when moving.
Causes of a Fractured Sternum
Several situations can cause a sternum fracture, some of which are:
- Car Accidents: Vehicle crashes are the leading cause of sternum fractures. A sudden stop can push the chest into the steering wheel or seatbelt, leading to a break. While airbags help reduce injury, they may not always prevent fractures in high-speed impacts.
- Blunt Force Trauma: A direct hit to the chest from sports, workplace accidents, or assaults can cause a fracture. Contact sports like football or rugby pose a higher risk.
- Falls: Falling from a height and landing on the chest can generate enough force to break the sternum, especially in older adults with weaker bones.
- Cardiopulmonary resuscitation (CPR): Chest compressions during CPR can sometimes result in sternum fractures, particularly in elderly patients or those with low bone density.
- Bone Weakness: Conditions like osteoporosis make bones fragile, increasing the risk of fractures from minor impacts or even severe coughing.
Impact of a Fractured Sternum on Daily Life
A fractured sternum can significantly affect a person’s daily routine. Some of the ways it can affect daily activities include:
- Pain with Movement: Bending, lifting, or even turning can be painful.
- Breathing Difficulties: Deep breaths, coughing, or sneezing can cause discomfort.
- Sleeping Problems: Finding a comfortable position may be challenging.
- Limited Physical Activity: Work and regular routines may be affected due to pain and restricted movement.
- Emotional Stress: Recovery time and limited mobility can lead to frustration and anxiety.
Conclusion
A sternum fracture is a serious injury that can impact daily life. It often results from car accidents, falls, or direct chest trauma. Symptoms like chest pain, swelling, and breathing difficulties require medical attention. While most fractures heal with rest and pain management, severe cases may require surgery. Preventive measures, such as wearing seatbelts and maintaining bone health, can help reduce the risk of sternum fractures.
