3 Anteroposterior radiograph of the hip of a fifty-seven-year old man fifteen years after left total hip arthroplasty, demonstrating evidence of left acetabular osteolysis. Paul S. Issack J Bone Joint Surg Am 2013;95:1981-1987 ©2013 by The Journal of Bone and Joint Surgery, Inc.

4 Three years after surgery, an anteroposterior radiograph shows reconstruction of the left acetabulum with a modular porous tantalum shell and superior hemispheric augment. Paul S. Issack J Bone Joint Surg Am 2013;95:1981-1987 ©2013 by The Journal of Bone and Joint Surgery, Inc.

5 Intraoperative photograph of a half-moon porous tantalum augment being fixed into a superior acetabular bone defect. Paul S. Issack J Bone Joint Surg Am 2013;95:1981-1987 ©2013 by The Journal of Bone and Joint Surgery, Inc.

6 A thin layer of cement (number 3) has now been applied to the exposed surface of the augment. Paul S. Issack J Bone Joint Surg Am 2013;95:1981-1987 ©2013 by The Journal of Bone and Joint Surgery, Inc.

7 The cup (number 4) has now been implanted into the acetabulum against the augment (number 1), and additional screws are being placed through the acetabular shell into the pelvis. Paul S. Issack J Bone Joint Surg Am 2013;95:1981-1987 ©2013 by The Journal of Bone and Joint Surgery, Inc.

8 Anteroposterior radiograph of the hip of a forty-year-old woman, demonstrating acetabular loosening, protrusion, and massive bone loss secondary to excessive medial wall reaming and postoperative infection.

9 Anteroposterior radiograph at two years postoperatively, showing reconstruction of the left side of the acetabulum with a modular porous tantalum shell, augment, screws, and demineralized bone matrix allograft.
