Preoperative (A) AP and (B) lateral radiographs of a 22-year-old man show a fractured cemented femoral stem 4 years after resection of a distal femoral osteogenic sarcoma. (C) An AP radiograph reveals mechanical failure, defined as a loss of compression between the anchor plug and spindle (asterisk), 5 months after placement of a revision CPS implant. (D) AP and (E) lateral radiographs taken 5 years after his second revision CPS implant show radiographic evidence of bone hypertrophy proximal to the spindle that is seen when there is osteointegration and an appropriately maintained traction distance (arrowhead).
