Abstract
An intrathoracic humeral head fracture is a rare injury usually caused by a high-energy force to the shoulder, resulting in medial displacement of the humeral head. This injury can be severe and life-threatening due to the proximity of the dislocated and fractured bone to the critical structures within the intrathoracic cavity. There are no current official guidelines for the treatment of such injuries. We report the successful treatment of a patient with an intrathoracic humeral head fracture that lacerated the thoracic aorta.
