Figure 3 Anteroposterior pelvis radiograph of a 45-year-old female who is status post bilateral total hip arthroplasties, each of which had been revised once for osteolysis. A: She presented with recurrent dislocations of her left total hip arthroplasty and having failed conservative management; B: the patient underwent a second revision of her left total hip arthroplasty with acetabular component exchange and exchange to a large femoral head. Intraoperatively, her stem was found to be relatively neutral, which likely contributed to her posterior instability.
