title: Foreign body giant cell reaction to polytetrafluoroethylene used as interposition material in scaphoid-trapezium arthroplasty.
abstract: We present the case of a 54-year-old woman who presented with a one and a half-year history of persistent pain at the base of her right thumb. A scaphoid-trapezium interposition arthroplasty with polytetrafluoroethylene was carried out in an effort to improve function and decrease the patient's persistent pain. Approximately 7 years after surgery, she began to complain of increasing pain and radiographs showed extensive osteolytic changes, consistent with a foreign body giant cell reaction.
