Fracture and intrathoracic displacement of the humeral head is the result of severe high energy trauma and are extremely rare. Because of the exceedingly limited number of cases, appropriate treatment modality remains unclear. Hitherto, we describe a unique case of thoracic aorta injury caused by fragmented humeral head. Purposeful medical examination and fast locating of the humeral head fragment are crucial for the selection of appropriate treatment modality. Early aggressive intervention, e.g., emergency thoracoscopy exploring, can be performed to treat potential thoracic complications.
