BackgroundManagement of posttraumatic large soft tissue defects and bone loss remains a therapeutic and surgical challenge for orthopedic surgeons. We assessed the use of a neurocutaneous flap and the Ilizarov technique in the reconstruction of severe composite defects in the tibia.MethodsWe retrospectively reviewed 18 consecutive patients with trauma-related soft tissue defects and bone loss. The size of the soft tissue defect ranges from 8 × 9 cm to 14 × 18 cm. The mean size of bone loss was 4.5 cm. A great saphenous neurocutaneous flap or sural neurocutaneous flap was created to reconstruct the soft tissue defect. The Ilizarov external fixator was applied to reconstruct bony loss by means of distraction osteogenesis.ResultsThe mean follow-up period was 38.8 months. All transferred flaps survived completely. The area covered ranged from 9 × 10 cm to 15 × 20 cm. The mean distraction length and duration of use of the external fixator were 6 cm and 11.4 months, respectively. All patients achieved final union. Complications of superficial pin-tract infections and mild Achilles tendon contracture were observed, but these were resolved over time. All patients were satisfied with the outcome of the surgery.ConclusionsA well-vascularized neurocutaneous flap is a safe and effective option in lower extremity reconstruction under a stable mechanical environment, which can be created using the Ilizarov technique. It is a good option for reconstructing severe complex defects in the lower limb.
