Mesh repair of a pelvic bone defect caused by a migrated acetabular cup

Conventional transacetabular removal of the migrated acetabular cup can be hazardous due to intraoperative injury to iliac vessels. We present a case of a migrated acetabular cup, in which we used a combined preperitoneal and acetabular approach for its removal. With a bimanual approach, the procedure was safer and easier and allowed mesh repair of the pelvic bone defect. The preperitoneal mesh repair is a well-known method for inguinofemoral hernias. However, it has not been used before in the repair of an acetabular defect after removal of a migrated cup.
