Vascularized fibular graft and callotasis using Ilizarov external fixator were used in the reconstruction of the diseased area after a wide resection for osteosarcoma in three cases. All cases were children with osteosarcoma of the leg. Preoperative and postoperative chemotherapy were effective in all cases, and no local recurrence or matastasis was seen. Wide resection was carried out. A vascularized fibula was grafted into the diseased area, and the Ilizarov external fixator was applied. Callotasis was then performed using the fixator. The results were not satisfactory due to poor callus formation. SAFHS was effective for two cases with poor callus formation. The remaining case however did not respond to SAFHS and additional intramedullary nailing with bone graft was therefore performed.
These results suggest that SAFHS provides good bone formation for poor callus formation which sometimes occurs during chemotherapy. Callotasis after chemotherapy can be used for reconstruction after wide resection for osteosarcoma.
