Background
- Due to segmental rib fractures (in 2 or more locations on same rib) of 3 or more adjacent ribs
- Leads to free-floating segment of ribs that no longer attach to rest of thorax
- Commonly associated with respiratory failure (due to pulmonary contusion)
Clinical Features
- Paradoxical movement of affected segment
- Inward movement of involved portion during inspiration, outward during expiration
- Often have concomitant pulmonary contusion[1]
Differential Diagnosis
Thoracic Trauma
- Airway/Pulmonary
- Cardiac/Vascular
- Musculoskeletal
- Other
Evaluation
Chest x-ray off a flail chest associated with right sided pulmonary contusion and subcutaneous emphysema.
- Possibly a clinical diagnosis
- Consider CXR or chest CT
Management
- Analgesia
- Consider positive pressure ventilation
- Otherwise healthy patients with mild-moderate flail chest may be managed without positive pressure ventilation
- Consider intubation even if patient's breathing initially seems adequate, especially if:
- Shock
- Severe head injury
- Comorbid pulmonary disease
- Fracture of 8 or more ribs
- Age >65
- Surgical fixation is controversial
Disposition
- Admit
See Also
- Thoracic Trauma
- Traumatic Pneumothorax
- Spontaneous Pneumothorax
- Tension Pneumothorax
