Rib Fracture Clinical Presentation

History
- Description of the prehospital scene by paramedics can provide important clues to the possibility of rib fractures.
- After motor vehicle collisions, deformation of the steering wheel and activation of seat belts and airbags have been associated with rib injuries.
- Patients with rib fracture frequently complain of pain on inspiration and dyspnea.
- Rib fractures have been reported after coughing spells without other significant trauma.
- Athletes with high force, recurrent movements of the arms (eg, discus throwers) have had stress fractures of the upper and middle ribs.[13]
- Consider nonaccidental trauma in pediatric cases and take an appropriate history for that diagnosis.
Physical
- Tenderness on palpation, crepitus, and chest wall deformity are common findings of rib fracture.
- Paradoxical chest wall excursion with inspiration is seen with flail chest. A flail chest occurs when a large segment of ribs is not attached to the spine. These ribs are broken in at least 2 places on each rib. The paradoxical movement occurs because the middle section of the rib between the 2 fracture sites moves in response to intrathoracic pressure changes not intercostal muscle contractions.
- Specific signs of ventilatory insufficiency include cyanosis, tachypnea, retractions, and use of accessory muscles for ventilation.
- Less specific signs include anxiety and agitation.
- Bruising near fracture site is uncommon in pediatric rib fractures, seen in 9.1% in one study.[11]
- If fracture of the lower ribs is suspected, assess the patient for abdominal tenderness and costal margin tenderness, which could raise suspicion for injury to intra-abdominal organs.[14]
