Postoperative radiographs show right proximal tibia after resection of metadiaphyseal osteosarcoma and reconstruction with an intercalary tibia allograft. Fixation of the allograft to the host was performed with a lateral buttress proximal plate and a medial dynamic compression plate. (A) Lateral radiograph of the right proximal tibia immediately after surgery that shows both osteotomy lines. (B) AP radiograph of the right proximal tibia 7 years after surgery that shows fracture of the intercalary allograft with loosening of the screws of the buttress plate. (C) Lateral radiograph of the right proximal tibia showing the fracture of the tibia intercalary allograft.
