Traumatic anterior dislocation of the hip joint with posterior acetabular wall fracture

The incidence of traumatic hip dislocation has increased in recent years as a result of high-energy trauma. Anterior hip dislocation forms less than 10-15% of all traumatic hip dislocations. Only a few case reports describe anterior dislocation along with acetabular fractures. The acetabular fracture involved the anterior wall or column in all such cases. We describe a rare case in which anterior superior dislocation of the hip was associated with a large fracture fragment of theposterior acetabular rim and adjacent wall.
