Emergency free-flap transfer for reconstruction of acute complex extremity wounds.

Nine patients with complex extremity injuries were treated with emergency free-flap transfers over a 3 1/2-year period. The transferred emergency free flaps were performed to cover exposed vital structures. All flaps survived without infection. Complete and careful assessment of the systemic condition of the patient and the nature of the injured extremity is mandatory. Emergency free-flap transfers may salvage the limb or finger and may improve the functional and aesthetic results with the shortest possible hospital stay.
