Abstract
Recently we have been performing biological reconstruction for malignant bone tumors of the extremities using frozen autografts. Here we present a case treated with free vascularized fibular graft (FVFG) after this method. A 23-year-old man developed osteosarcoma in his left distal tibia. There was nonunion after frozen autograft reconstruction, which we treated with FVFG. Twenty-four months later, bridging between the host bone and the frozen autograft was achieved. Our department has achieved bone union in almost all cases, but we sometimes encounter cases of nonunion after this method because of delayed blood supply. In these instances, reconstruction using FVFG may represent an attractive choice for salvage treatment.

Summary
There has been much progress in multidisciplinary treatment for malignant bone tumors including chemotherapy, radiation therapy and immunotherapy. Long-term survival can be expected in patients with malignant bone tumors of the extremities and importance has begun to be placed on preservation of functions in the affected extremities. Since January 1999, our department has been performing biological reconstructtion in patients with malignant bone tumors of the extremities [1]. Our method involves reconstruction using tumor-bearing autologous bone graft treated with liquid nitrogen. We report a case of osteosarcoma of the distal tibia that was treated with frozen autograft reconstruction and subsequent reinforcement with a free vascularized fibular graft (FVFG)
