Aseptic, simultaneous and bilateral mobilization due to an acetabular shell fracture in a 43 year-old patient ☆

Abstract The acetabular shell mobilization is the main long-term complication in total hip replacement. Metal-back fracture has also to be considered among the possible causes of shell mobilization. A case is presented of bilateral acetabular shell mobilization due to the trabecular covering de-soldering from the metal-back in a 43 year-old patient, 13–14 years after the first surgery.
