[Our experience with endoprosthesis in surgery for bone tumors].

Endoprosthesis is a method allowing a valuable substitution of bone defects (articular ends of long tubular bones, both articular ends of the bones making the articulation, whole long tubular bones with articulations). The employment of endoprostheses is expedient for the substitution of defects of the breast bone, pelvis, hand bones as well. Endoprosthesis in combination with preoperative radiotherapy and post-operative modern chemotherapy allows preserving the extremities in certain patients with osteogenic sarcoma, chondrosarcoma, reticulosarcoma, chondrosarcoma and solitary plasmacytoma. The experience with 204 operations of endoprosthesis of bones is presented.
