Clinical outcome of first web flap transfer from the foot for coverage of first web and finger pulp defects

Objective To evaluate the treatment outcomes of transfer of the web flap from the foot for coverage of soft tissue defect of the first web space and finger pulp. Methods First web flap from the foot was harvested and transferred to the hand for soft tissue coverage in 7 cases, among which 2 were scar contracture of the first web space and 5 were post-traumatic loss of finger pulps. The donor sites were closed by full thickness skin graft. Results All 7 flaps survived. Post-operative follow-up averaged 8 months. Opening of the contractured first web space reached 70% of the opposite side. The resurfaced fingers had good appearance and range of motion. 2-PD was 10-12 mm. Donor site morbidity included scar formation at the toe web in 2 cases. There was no pain. All patients could walk normally at 3 months post-operatively. Conclusion Transfer of the web flap from the foot for coverage of soft tissue defect of the first web space and finger pulp is technically demanding but rewarding in terms of sensory recovery.
