Arthroscopic loose body retrieval following traumatic hip dislocation.

Traumatic dislocation of the hip is associated with considerable morbidity due to the risk of aseptic necrosis and post-injury arthritis, which is greater in the presence of an associated fracture. Computed tomography after a traumatic dislocation may reveal loose bone fragments within the weight-bearing area of the joint. We advocate the early arthroscopic retrieval of loose bone fragments to preserve the articular surface, as the retention of such fragments may lead to a less satisfactory long-term result. Arthroscopic surgery is associated with less morbidity than open arthrotomy.
