Posterior Hip Dislocation Associated with Acute Traumatic Injury of the Thoracic Aorta: A Previously Unrecognized Injury Complex

SummaryPosterior hip dislocation associated with acute injury to the thoracic aorta is a previously unrecognized injury complex. This study reveals that 8% of patients with posterior hip dislocation have associated injury to the thoracic aorta because of abrupt deceleration injuries. This study defines the association of traumatic posterior hip dislocation and acute traumatic injury of the thoracic aorta, describes the mechanism of injury, and discusses the evaluation of a patient with a suspected acute traumatic aortic injury.
