Intraoperative dislocation of a trial femoral head into the pelvis during total hip arthroplasty.

for total hip arthroplasty have become popular over the past few years. However, the shorter incision leads to higher soft-tissue tension, increasing the chances for dislocation. We describe the case of a woman who underwent total hip arthroplasty by a minimally invasive variation of a common arthroplasty procedure and suffered dislocation of the femoral component from the acetabulum into the pelvis.
