    INPUT: The cardiomediastinal silhouette is normal . The hila and pleura are unremarkable . No focal consolidations , pleural effusions , or pneumothorax are seen . Left humeral head replacement and associated hardware are seen . If the demonstration of trauma to the chest wall is clinically warranted , the location of any referable focal findings should be clearly marked and imaged with either bone detail radiographs or Chest CT scanning . Given patient 's history of shoulder repair all follow - up dedicated shoulder views are recommended .
    OUTPUT:
    
No evidence of left rib fracture within the limitations of plain film radiography .
