title: Acetabular component migration following traumatic total hip dislocation. A case report.
abstract: A 40-year-old man with a total hip arthroplasty was injured in an auto accident. The injury was a posterior fracture-dislocation of the total hip and produced migration of a dislocated acetabular prosthesis. A large hematoma extended from the hip to the medial aspect of the thigh. This unusual case illustrates the importance of obtaining serial roentgenograms for hip arthroplasties and for injuries of the hip joint.
