Abstract

Acetabular bone defects in revision hip arthroplasty are a challenging problem. Its treatment relies on preoperative and intraoperative assessment of the size of the defect, presumed quality of the bone, integrity of the acetabular columns and presence of pelvic discontinuity. Several surgical techniques advocated for treating pelvic discontinuity are ilio-ischial cages, plate fixation of structural allograft, triflange cups, Steinmann pin fixation, acetabular revision with additional pelvic screws, acetabular reinforcement rings, oblong cups and cup-cage reconstruction [1- 5]. Severe cases of acetabular bone loss often require an implant specifically made to match the patient’s individual anatomy. Triflange acetabular component is a patient-matched implant designed in partnership with the surgeon, using the patient’s own computed tomogram (CT) scan data. We present a case with severe acetabular bone loss treated with a custom triflange acetabular cup.
