title: Reimplantation of autoclaved or irradiated cortical bones invaded by soft tissue sarcomas.
abstract: BACKGROUND
  Bone defects after excision of malignant bone and soft tissue tumors are usually reconstructed by autogenous bone grafting or allografting.
  
  
  METHODS
  We treated 2 patients who had soft tissue sarcomas with bone involvement, the first by excision and reimplantation of the hemicortical autogenous cortical bone graft after autoclaving and the second with intraoperative irradiation.
  
  
  RESULTS
  In both patients, postoperative follow-up radiographic studies showed incorporation of the implanted bones into the host bones within 12 months. Biopsy of the implanted bone performed 3 years after surgery showed many viable osteocytes, and blood vessel invasion into Harversian canals. No complications regarding the reconstructive techniques were observed during the postoperative period.
  
  
  CONCLUSIONS
  The reimplantation of autogenous cortical bones after autoclaving or irradiation is a useful reconstructive method for partial bone defects in soft tissue tumor surgery.
