Free posterior tibial perforator flap for coverage of donor defect of the big toe after free lateral pulp flap transfer

Abstract

Objective To explore the application of free posterior fibial artery perforator （PIP） flap for coverage of donor defect of the big toe after free lateral pulp flap transfer and decreasing donor site morbidity. Methods From June 2009 to December 2010, 5 cases of soft tissue defect of the thumb and fingers were treated by free transfer of the lateral pulp flap from the big toe. The resulting defects of the donor big toes were repaired by free PIP flap transplantation. Flap donor sites at the calf were directly closed. Results All flaps survived with desirable appearance and sensation, Mean follow-up time was 7 months. Two-point discrimination in the lateral pulp flaps transferred to the thumb and fingers and in the PIP flaps was 5 mm and 7 mm, respectively. Conduslon PIP flap transfer for coverage of donor big toe defect resulted from flee lateral pulp flap transfer is an ideal surgical procedure. It prevents donor site morbidities such as pain and ulceration. Key words: Surgical flaps; Finger injuries; Soft tissue injuries
