Management of Unreported Fractures

Clinical Significance of Unreported Fractures

  • Multiple rib fractures carry prognostic significance and directly correlate with increasing morbidity and mortality, particularly in patients ≥65 years with poor cardiopulmonary reserve, as stated by the American College of Radiology 1, 2
  • The number and displacement of fractures predict subsequent complications including opioid requirements, pulmonary morbidity, and need for surgical intervention, according to the American College of Radiology 2
  • Specific fracture patterns require urgent evaluation: ≥6 rib fractures, bilateral fractures, flail chest, ≥3 severely displaced fractures, first rib fracture, or fractures in all three anatomic areas, as recommended by the American College of Radiology 1, 2

Assessment and Documentation of Fractures

  • For rib fractures, count total number of fractures, assess for bilateral involvement, evaluate displacement severity, check for first rib involvement, determine anatomic distribution, and look for complications, as suggested by the American College of Radiology 1, 2
  • Document your direct communication including date, time, and person contacted, and specify the exact location and number of unreported fractures with semiquantitative descriptors, as recommended by the Radiology society 3

Imaging and Management

  • Ultrasound can detect fractures invisible on radiographs, and evaluates costochondral junction, costal cartilage, and nondisplaced fractures, as stated by the American College of Radiology 1
  • CT provides superior fracture characterization, with 100% sensitivity for tibial plateau fractures, and is essential for preoperative planning in complex fractures, according to the American College of Radiology 5
  • MRI is indicated when radiographically occult fractures are suspected, soft-tissue injury assessment is needed, or osteochondral lesions are suspected, as recommended by the American College of Radiology 6, 5

Pain Control and Surgical Consultation

  • Pain control becomes more critical with multiple fractures, and multiple fractures increase pulmonary complications risk, as stated by the American College of Radiology 2
  • Consider regional anesthesia techniques for multiple rib fractures, and surgical consultation may be needed for multiple fractures or flail segments, as suggested by the Praxis Medical Insights society 4

Common Pitfalls to Avoid

  • Never assume the radiology report is complete without personally reviewing images, and do not rely solely on chest radiographs for rib fractures, as recommended by the American College of Radiology 8, 4
  • Avoid overlooking associated injuries with lower rib fractures, particularly abdominal organ damage in polytrauma, as stated by the American College of Radiology 1, 2
