A broken breastbone from a crash: breathing and moving while it heals

Insight from a trauma specialist and a respiratory therapist on chest wall recovery

The sternum, or breastbone, sits in the center of your chest. A hit from the steering wheel or seat belt can break it. Pain often gets worse when you cough, laugh, breathe deeply or get out of bed. [1, 2]

The same force can also hurt the ribs, lungs or heart. A trauma specialist checks for these related injuries. A respiratory therapist helps you take deep breaths even though you’re sore. [1, 2]

Know what the tests found and ruled out

Ask whether the broken bone is lined up and whether the scan found other chest injuries. Find out whether you needed a heart blood test or an electrocardiogram, which tracks the heart’s electrical signals. Ask what those tests showed. [1, 2, 3]

Don’t assume a broken breastbone means your heart was hurt. Likewise, don’t assume your heart was checked just because the break was found. Ask for a plain language summary of what the hospital found. [1, 2, 3]

Plan your movement around your breathing

Take pain medicine as prescribed so you can breathe deeply, cough and walk. Ask a therapist to show you how to cough while supporting your chest. Have them show you a safe way to get up from a chair or bed, too. [1, 2]

Keep moving within the limits set for your other injuries. Ask when you can lift, drive, work and exercise again. A job with physical labor may need a different plan than a desk job. [1, 2]

Pain that doesn't fit normal soreness

Get emergency care for new, severe chest pain, fainting, trouble breathing or a new irregular heartbeat that doesn’t go away. Call your care team about a fever or a cough that gets worse. Also call if pain still keeps you from breathing deeply despite treatment. These can be signs of a chest infection or another problem. [1, 2]

Questions about your chest injury

  1. What other chest or heart injuries did you check for?
  2. What pain plan will let me breathe and move?
  3. When is it safe for me to drive, lift and work?

Practice your breathing routine before you go

Before you leave the hospital, practice your breathing routine. Write down the symptom that should bring you back. [1, 2]
