Thenar flap rehabilitated: a review of 20 cases.

The thenar flap is a satisfactory reconstruction technique for the treatment of extensive loss of the distal phalanx of the index and middle fingers. As we observed in this series of 20 patients, this flap is reliable and provides tissue that closely matches the missing finger pulp. Flap sensibility is good (average Weber of 6.5 mm). Transferring a distally based flap prevents proximal interphalangeal joint contracture and allows the surgeon to better reconstruct the outlines of the distal phalanx, thereby reducing the risk of a clawed nail. Finally, we did not observe major postoperative complications at the donor site.
