title: Osteosarcoma eight years after total hip arthroplasty.
abstract: This report presents a case of osteosarcoma of the femoral diaphysis associated with chronic stimulation of the area by an unstable femoral prosthesis after total hip arthroplasty performed 8 years previously. The pathogenesis of this transformation may be similar to that proposed for fracture-associated sarcoma. Neoplasia should be considered as a possible late complication of total hip arthroplasty.
