Intra-pelvic migration of femoral head trial in total hip arthroplasty, a rare intra-operative complication: a systematic literature review.
Trial reduction while performing total hip replacement is an essential step of the procedure. This is to check the stability of the hip joint with the selected implant sizes and to assess the leg length to avoid discrepancy. Disengagement of the femoral head trial from the femoral rasp stem with subsequent migration of the trial head into the pelvic cavity is a rare occurrence, but can be a very frustrating complication to both the surgeon and occasionally the patient. We present our experience with this exceptional situation and different management options, together with systematic review of the literature.
