Pitfall in total hip arthroplasty: intraoperative migration of the trial femoral head through the iliopsoas muscle.

Total hip arthroplasty is actually one of the most orthopaedic procedures realised to treat a lot of conditions in hip pathology. Complications associated with this operation are well established and reported in the medical literature. Only few cases of intraoperative dislocation of the trial femoral head had been reported; we present a case of intraoperative intrapelvic dislocation of the trial femoral head through the iliopsoas muscle during total hip replacement with a standard posterolateral approach of Moore.
