Dorsal Ulnar Flap (Becker Flap): Case Report of Reconstruction in High-Voltage Electrical Burn

Abstract

ABSTRACT High-voltage electrical burns pose a substantial challenge for reconstructing wrist defects, often requiring complex microsurgical options. The dorsal ulnar flap is a safe, versatile, and reproducible alternative for covering proximal defects in the hand and distal third of the forearm, with good functional and aesthetic outcomes. A 48-year-old male patient presented with an electrical burn on the right upper extremity, affecting the palm, wrist, and exposing the tendon structures, which required a flap for coverage. The defect was treated with a dorsal ulnar flap (Becker flap), achieving adequate coverage. The dorsal ulnar flap is a reliable and useful tool for reconstructing distal forearm and wrist defects. It can address complex defects with good results by use of skin with similar characteristics and without compromising distal blood supply. The dorsal ulnar flap is a viable option for covering complex defects in electric burns of the distal upper limb, avoiding the need for microsurgery.
