Finger pulp reconstruction with free dorsoulnar artery perforator (DUAP) flap

Finger pulp is a common site for hand injuries, and pulp reconstruction is significantly important for optimal handling and sensation. Ideal substitute must provide matching texture, tenacity, and slim subcutaneous fat. This article presents six cases in which fingertip and finger pulp reconstruction were performed via free dorsoulnar artery perforator (DUAP) flap. All flaps survived and all patients healed uneventfully without any complications by the end of at least 3 months follow-up. Free DUAP flap has proved to be a suitable substitute for pulp reconstruction with its thin structure, minimally morbid donor site which is also close to the trauma zone, and possibility for neurotization. It can be especially favorable when splitting the surgical team for a glabrous flap harvest from the foot is not possible.
