Background

Anatomy of the sternum.
  • Fracture is more likely in restrained passengers than unrestrained passengers (high-energy trauma)
  • Isolated sternal fracture is relatively benign
    • Low mortality (<1%)
    • Low intrathoracic morbidity
  • Sternal body fracture most common

Associated Injuries

Clinical Features

  • Anterior chest pain
  • Point tenderness over sternum
  • Ecchymosis, soft tissue swelling

Differential Diagnosis

Thoracic Trauma

Evaluation

A displaced sternal fracture as seen on lateral X-ray.
Comminuted sternal fracture on CT
Axial CT showing sternal fracture with retrosternal haematoma (black arrow). Also aortic injury (white arrows).

Workup

Diagnosis

  • Most are visible on lateral CXR
  • CT is test of choice if high suspicion

Management

Disposition

  • Isolated, non-displaced fracture:
    • If pain control achieved and ECG normal ok to discharge home
  • Displaced fracture or concern for severe pain or respiratory compromise:
    • Refer for operative fixation
