Three vascularized fibula transfer were carried out to bridge the defects of one humerus and two tibia and they have been followed up to 6-10 months. The first case had a humerus defect of the dominant arm which had been previously bridged twice with the conventional non-vascular iliac bone grafts, followed by non-union. The second transfer was carried out to an extensive tibial defect, due to a gun-shot injury. In these two patients, it was not possible to monitor the circulation of the graft in the early postoperative period. Therefore a skin flap was included with the bone graft in the third case to cover the overlying skin defect and it was also used as a monitoring flap.
