Hip dislocations--epidemiology, treatment, and outcomes

Abstract

Traumatic dislocations of the hip appear to be on the rise in North America. Multidetector CT, hip arthroscopy, and high field MRI have further defined the pathoanatomy of hip dislocations. They can be divided into simple and complex dislocations. At the University of Louisville, an algorithm has been developed to facilitate rapid and accurate diagnosis and treatment of simple hip dislocations. In contrast to the treatment of simple hip dislocations, the treatment of complex hip dislocations (fracture-dislocations) is generally predicated on specific treatments of the associated fracture (e.g., femoral head fracture, femoral neck fracture, acetabular fracture, etc.). This review includes the mechanism of injury, epidemiology, associated injuries, evaluation, treatment, and functional outcomes of simple hip dislocations.
