Chest Wall Injury: Bruises, Strains and Fractures

Types of chest wall injury

What can be injured underneath

• Pneumothorax: air leaks around the lung, which collapses. Sudden sharp pain and breathlessness.
• Hemothorax: blood collects in the chest. Breathlessness and signs of blood loss.
• Pulmonary contusion: bruising of the lung tissue, which may worsen over 24 to 48 hours.
• Cardiac contusion: bruising of the heart, causing irregular rhythms; linked to sternal fractures.
• Liver or spleen injury with lower rib fractures.

Causes

• falls, especially in older adults
• car crashes (steering wheel, seat belt, airbag)
• contact sports and direct blows
• assaults
• severe coughing (can fracture ribs, especially with osteoporosis)
• CPR, which commonly fractures ribs or the sternum
• lifting, twisting or overreaching (muscle strains)

Symptoms

• pain at the site, worse with deep breaths, coughing, sneezing, laughing or moving
• tenderness and bruising
• shallow breathing to avoid pain
• a crunching or grating feeling with rib fractures
• shortness of breath, if the lung or many ribs are affected

Diagnosis

A doctor will examine the chest, listen to the lungs, check oxygen levels, and look for signs of injury beneath.

• Chest X-ray: looks for a collapsed lung, blood in the chest and displaced fractures. Simple rib cracks are often missed on X-ray, which does not change treatment in minor injuries.
• CT scan: for high-energy injuries, older adults, multiple fractures or suspected internal injury.
• Ultrasound: quickly detects air or blood around the lung.
• ECG and blood tests after a sternal fracture or major blow to check the heart.

A minor bruise or strain in a young, healthy person with normal breathing often needs no imaging.

Treatment

Pain control: the key to recovery

Pain makes people breathe shallowly and avoid coughing, which lets mucus build up and causes pneumonia. Good pain relief is not just comfort; it prevents complications.

• acetaminophen (paracetamol) regularly
• ibuprofen or naproxen, if safe for you (avoid with kidney disease, stomach ulcers or some heart conditions). Follow the label dose
• ice packs for 15 to 20 minutes several times a day in the first 2 days
• stronger prescription painkillers or nerve blocks in hospital for multiple fractures, particularly in older adults

Breathing exercises

• take 10 slow, deep breaths every hour while awake
• cough to clear mucus, hugging a pillow against the chest for support
• an incentive spirometer may be provided in hospital

Activity

• stay active and walk; do not stay in bed
• sleep slightly upright for the first few nights if lying flat is painful
• avoid heavy lifting and contact sports until pain has resolved, usually 4 to 6 weeks
• do not strap or wrap the chest tightly, which restricts breathing and raises pneumonia risk

Hospital treatment

Needed for complications: a chest tube for collapsed lung or blood, oxygen, heart monitoring, and sometimes surgical fixation of ribs for flail chest or severely displaced fractures.

Healing time

• bruises and strains: 1 to 3 weeks, sometimes longer
• rib fractures: about 6 weeks to heal; pain can last longer
• sternal fractures: 6 to 12 weeks
• costochondral injuries: several weeks to a few months

Frequently asked questions

How do I know if I bruised or broke a rib?

Both hurt with breathing and movement. A fracture is more likely if pain is very sharp at one spot, you felt or heard a crack, or pressing on another part of the rib cage causes pain at the injury site. Treatment is similar unless there are complications, which is why X-rays are not always needed.

How long does a chest wall injury take to heal?

A bruised chest or strained muscle usually improves in 1 to 3 weeks. Rib fractures take about 6 weeks to heal, and a broken sternum 6 to 12 weeks. Pain often lingers for a while after the bone has healed.

When is chest pain after an injury serious?

Get emergency help for worsening shortness of breath, coughing up blood, a racing or irregular heartbeat, fainting, or a section of the chest moving abnormally. These suggest injury to the lungs or heart. High-energy injuries should always be checked.

Should I wrap my chest after an injury?

No. Tight strapping or binding stops the lungs from expanding fully and increases the risk of pneumonia. Instead, control pain, take regular deep breaths and support your chest with a pillow when coughing.

Can a chest injury cause pneumonia?

Yes. Pain from chest injuries leads to shallow breathing and avoiding coughing, so mucus builds up in the lungs. This risk is highest in older adults and people with lung disease. Good pain relief and deep breathing exercises help prevent it.
