Anteroposterior radiographs show the left hip of a 61-year-old man who underwent resurfacing for osteoarthritis. (A) A routine radiograph in the recovery room showed his acetabular cup had shifted, so (B) he was taken back to the operating room where an inserter was used to reposition the cup. (C) It was well-fixed at the 2-year followup.
