A fractured sternum is a painful chest injury that can occur after a strong impact to the front of the body. Because the sternum, also known as the breastbone, sits in the center of the chest and connects to the ribs, any damage to this bone can significantly affect breathing, movement, and overall comfort. Many people associate chest pain with heart problems, but trauma-related pain after an accident could point to a sternum fracture. Understanding fractured sternum symptoms is important so that proper medical care can be sought quickly and complications can be avoided.
What Is the Sternum?
The sternum is a flat bone located in the middle of the chest. It connects to the rib cage through cartilage and helps protect vital organs such as the heart and lungs. Together with the ribs and spine, the sternum forms the rib cage, which provides structural support and protection.
Because of its central location, the sternum absorbs force during impacts such as car accidents, sports injuries, or falls. When the force is strong enough, it can cause a crack or complete break in the bone, leading to a fractured sternum.
Common Causes of a Fractured Sternum
Sternal fractures are most often linked to blunt chest trauma. Some of the most common causes include
- Motor vehicle collisions, especially from seatbelt impact
- Contact sports injuries
- Falls from significant heights
- Direct blows to the chest
- Physical assaults
In rare cases, severe coughing or medical procedures such as chest compressions during CPR can also result in a sternum fracture.
Main Fractured Sternum Symptoms
The symptoms of a fractured sternum can vary depending on the severity of the injury. However, several signs are commonly reported.
Severe Chest Pain
The most noticeable fractured sternum symptom is sharp or intense pain in the center of the chest. The pain often worsens when taking deep breaths, coughing, or moving the upper body. Pressing on the chest area may also increase discomfort.
Swelling and Bruising
Visible swelling, tenderness, or bruising over the breastbone area is common after chest trauma. The skin may appear discolored due to internal bleeding under the surface.
Pain When Breathing
Because the sternum moves slightly during breathing, a fracture can make inhaling and exhaling painful. Some individuals may take shallow breaths to avoid discomfort, which can increase the risk of lung complications.
Clicking or Grinding Sensation
In certain cases, a person may feel or hear a clicking sensation when moving the chest or arms. This may indicate movement at the fracture site.
Additional Symptoms to Watch For
Beyond localized pain, other symptoms may appear depending on the extent of the injury and whether nearby structures are affected.
- Shortness of breath
- Rapid heartbeat
- Dizziness or lightheadedness
- Nausea
- Pain radiating to the shoulders or back
These symptoms may suggest associated injuries to the lungs, heart, or ribs, which require immediate medical evaluation.
How a Fractured Sternum Is Diagnosed
If a sternum fracture is suspected, a healthcare provider will perform a physical examination and ask about the injury. Imaging tests are usually required to confirm the diagnosis.
X-Ray
A chest X-ray can help detect obvious fractures. However, some small cracks may not be clearly visible.
CT Scan
A computed tomography (CT) scan provides more detailed images and is often used to evaluate the extent of the fracture and check for internal injuries.
Electrocardiogram (ECG)
Because the sternum lies close to the heart, doctors may perform an ECG to monitor heart function and rule out cardiac injury.
When to Seek Immediate Medical Attention
Not all chest injuries are simple bruises. Seek emergency care if any of the following occur
- Difficulty breathing
- Severe or worsening chest pain
- Fainting
- Irregular heartbeat
- Signs of shock, such as pale skin or confusion
Prompt evaluation ensures that potentially life-threatening complications are identified early.
Potential Complications
While many sternum fractures heal without surgery, complications can occur, especially if other injuries are present.
Lung Contusion
A lung contusion is a bruise to lung tissue that can interfere with oxygen exchange. It may accompany chest trauma.
Cardiac Contusion
In rare cases, the heart muscle can be bruised, leading to rhythm abnormalities.
Rib Fractures
It is common for rib fractures to occur alongside a sternum fracture, increasing overall chest instability.
Treatment Options for a Fractured Sternum
Most fractured sternum cases are treated conservatively, meaning surgery is not required.
Pain Management
Doctors often recommend over-the-counter or prescription pain relievers to help manage discomfort. Effective pain control is important to allow normal breathing and prevent lung complications.
Rest and Activity Modification
Avoiding heavy lifting, strenuous exercise, and movements that strain the chest is essential during recovery.
Breathing Exercises
Deep breathing exercises may be recommended to prevent pneumonia and maintain lung function.
Surgical Intervention
Surgery is rarely needed but may be considered if the fracture is severely displaced or unstable.
Recovery Time and Healing Process
Healing time for a fractured sternum typically ranges from six to twelve weeks. Recovery depends on factors such as age, overall health, and the severity of the fracture.
During the healing period, gradual improvement in pain levels is expected. However, mild discomfort during certain movements may persist for some time.
Preventing Sternum Injuries
While accidents cannot always be avoided, certain precautions reduce the risk of chest injuries
- Wear seatbelts properly in vehicles
- Use protective gear during sports
- Follow workplace safety guidelines
- Maintain strong bone health through nutrition and exercise
Strengthening core muscles may also help support the upper body and reduce injury risk.
Distinguishing Fractured Sternum Symptoms from Other Conditions
Chest pain can have many causes, including muscle strain, rib injuries, or heart conditions. Trauma-related chest pain that worsens with movement or pressure often suggests a musculoskeletal cause rather than a cardiac event. However, because heart-related chest pain can be serious, it is always wise to seek medical evaluation if the cause is unclear.
A fractured sternum is a significant injury that should not be ignored. Recognizing fractured sternum symptoms such as central chest pain, swelling, breathing discomfort, and tenderness can help individuals seek timely medical care. Although most cases heal with rest and pain management, monitoring for complications is essential. With proper diagnosis, supportive treatment, and careful recovery, many people return to normal activities without long-term problems. Understanding the warning signs and knowing when to seek help can make all the difference in achieving a safe and complete recovery.
