Abstract

Introduction: Improved patient prognosis and better local control of the tumor widened the indications to limb salvage. Endoprosthetic devices allow for one early weight bearing and good functional results.Purpose: To review the experience of the Rizzoli Institute with the use of tumor prostheses in bone tumor surgery.Methods: From April 1983 to June 1995 475 prostheses were used for reconstruction in patients with bone tumors. Most frequent histotypes were osteosarcomas (298) and. chondrosarcomas (52). Locations were the proximal femur (73), distal femur (280), proximal tibia (97), femur and tibia (5), total femur (7), proximal humerus (7), elbow (4), total humerus (2). Modular Replacement prosthetic system was used (HMRS from Howmedica). Since 1989 allograft prosthesis composites were preferred in proximal humerus (5), proximal femur (22) and proximal tibia (19).
