Free Vascularized Osteocutaneous Fibular Graft to the Tibia in 51 Consecutive Cases

The authors reviewed retrospectively the clinical results of 51 consecutive cases of vascularized osteocutaneous fibular graft to the tibia for the reconstruction of extensive tibial bone and soft-tissue defects. The mean duration of follow-up was 31 months (range: 13 to 76 months). In the 51 procedures of free vascularized osteocutaneous fibula graft from the contralateral side, bony union was achieved in 48 cases at an average of 3.74 months after the operation, except for two cases of non-union and two cases of delayed union. Forty-eight cutaneous flaps survived, and three cutaneous flaps failed due to deep infection and venous thrombosis. All united fibulae hypertrophied during the follow-up periods. Stress fracture of the grafted fibula was the most common complication (16 cases), and it was treated with above-the-knee cast immobilization or internal fixation with a conventional cancellous bone graft. The free vascularized osteocutaneous fibular graft is recommended as a useful treatment modality for the reconstruction of extensive tibial defects combined with soft tissue injury.
