case_images: Initial X-ray of the fracture. After a stumble fall, the patient presented herself to an orthopedist. An anteroposterior X-ray of the pelvis was conducted and showed a fracture of the pelvis with a dislocation of the prosthesis.

case_images: The resident doctor conducted computed tomography (CT) and native x-rays on the hip to reveal the affected part (Figures 1 and 2).
case_images: Preoperative CT of the pelvis. (a) shows the large osteolysis in the sagittal plane. (b) is the corresponding coronal plane of the patient's left hip.

case_images: The resident doctor conducted computed tomography (CT) and native x-rays on the hip to reveal the affected part (Figures 1 and 2).
case_images: CT volume rendering of the pelvis. The reconstruction of all CT planes gives an overview of the fracture of the Os ilium and the extent of the cyst.

case_images: The ilium, the pubis, and the sciatic bone were lined with pronounced osteolytic linings (Figure 3).
case_images: Metallotic pseudotumor. (a) shows the intraoperative metallosis with pronounced osteolysis. (b) shows the resected metallotic tissue after a complete surgical debridement.

case_images: The acetabulum was debrided, and the metallosis was shown here at the smaller pelvis, carefully and extensively debrided (Figure 4).
case_images: Surgical reconstruction after implantation of a cemented THA. (a) is an anteroposterior X-ray of the pelvis that shows the postoperative situation. On the left side, the patient carries a McMinn-like prosthesis without any symptoms or functional deficits. In (b), the bony acetabular reconstruction is observed. The cup was fixated with three screws to increase rotatory stability.

case_images: Carried out is the femoral implantation of a Lubinus Classic Plus shaft (Waldemar Link GmbH, Hamburg, Germany), size 4, 126  CCD angle, 150 mm long (Figure 5).
case_images: Follow-up X-ray 6 months after surgery. The anteroposterior view of the pelvis shows the correct placement of the implants and a boney healing of the Os ilium.
