BACKGROUND: Large femoral defects after trauma, femoral non-unions, fractures complicated by osteomyelitis or defects after bone tumour resection present high burden and increased morbidity for patient and are challenging for reconstructive surgeons. Defects larger than 6 cm and smaller defects after failed spongioplasty are suitable for reconstruction using a free, eventually a pedicled vascularised bone flap. The free fibular flap is preferred but an iliac crest free flap or a pedicled medial femoral condyle flap can be also used. These vascularised flaps are ideal for bridging defects of long bones and can be also used as osteocutaneous or osteomuscular flaps for coverage of soft tissue defect if present. The patients and their families were informed that data will be submitted for publication and they gave their written informed consent prior to the submission. The study was approved by the institutional ethic committee. METHODS: We analysed a group of eight patients with large diaphyseal or distal metaphyseal femoral defects. A free fibular flap was used in six patients, a pedicled medial ipsilateral femoral condyle flap was used in two patients and a defect in one patient was reconstructed using an iliac crest free flap. RESULTS: All flaps healed completely in all patients and no fracture of the flap was detected during the study period. In one patient, a locking plate broke and was replaced by a compression plate. At the last check-up all patients were able to step on the reconstructed limb with full weight. DISCUSSION: Although our study comprises a heterogeneous group of cases, they all have been successfully treated by a similar technique, adapted in each case specifically to the needs of the patient. A major limitation parameter of reconstruction by a free vascularised flap is the size of bone defect needed to be reconstructed. In case of a bone defect longer than 6 cm and a concomitant soft tissue disruption, a vascularised double-barrel fibula is the preferred. CONCLUSION: Large femoral defects can be successfully reconstructed with good long-term results using suitable free or pedicled vascularised bone flaps, especially preferring the free fibular flap.
