Patient 2: 14-year-old boy with osteosarcoma of the distal femur. (A) Plain radiograph showing changes at the distal femur. (B) Magnetic resonance imaging scan showing the intramedullary extent of the tumor (180 mm). A further 30 mm was resected proximally during surgery, making a total of 210 mm of bone that was autoclaved and replaced. (C) Intra-operative photograph showing the autoclaved tumor bone placed in its original bed. (D) Post-operative radiograph showing fixation of the autoclaved tumor bone with a long locking plate and a 3.5 dynamic compression plate at the proximal junction. (E) Follow-up 14 months later; bone union and full weight-bearing without aids.
