Intrapelvic extension of polymethylmethacrylate (PMMA) poses a dilemma for the surgeon during revision arthroplasty. Its presence indicates that the medial wall has been compromised, either during the previous joint procedure or from trauma or osteolysis. When the medial acetabular wall has been violated the intraabdominal contents of the pelvis become at risk. These structures include the ureter, vagina, rectum, and most importantly, the iliac vessels.1 (See Part 5, Chapter 59.)
