a) Anteroposterior (AP) pelvic radiograph of a 75-year-old female with a painful, aseptically loose right revision acetabular component showing protrusion of right cementless porous cup (prior cemented cup). CT scan showed segmental bone loss of anterior column and medial quadrilateral plate. b) Postoperative AP pelvic radiograph showing pelvic reconstruction with MaxTi triflange cage. 18 ml of Cerament was injected behind the cage into all defects before cementing the acetabular component into the cage. c) AP pelvic radiograph 16 months postoperatively. Pelvic reconstruction remains stable. Note the area of Cerament where remodelling has occurred. Remodelling has progressed to an appearance that suggests transformation into bone. Also note the removal of 15 mm of superior ramus screw tip which exited the anterior cortex and was a focal area of discomfort when wearing pants. The exposed screw was removed at 14 months postoperatively with a limited incision.
