title: [Osteosarcoma of the radius after intramedullary osteosynthesis].
abstract: Osteosarcoma is a malignant neoplasm characterized by local lytic or plastic processes. We observed a case of radius osteosarcoma in a 10-year-old boy 3 months after intramedullary osteosynthesis in the ipsilateral distal radius. Treatment consisted of amputation of the distal humerus and adjuvant chemotherapy; no complications were observed.
