Dorsal V - Y Advancement Flap for Lateral Finger Defect Based on Dorsal Skin Branch of Proper Digital Artery.

Managing lateral soft tissue defects, distal to the proximal interphalangeal joint, of the finger can be challenging. The use of antegrade homodigital island flap can be limited due to the length of the defect. Using a heterodigital island flap can be precluded by an injury in the adjacent fingers. Using the locoregional flap from the hand can result in a more extensive soft tissue dissection, which can create additional donor site morbidity. We present our execution technique of the homodigital dorsal skin advancement flap. The pedicle of the flap is based on dorsal branches of the digital artery perforator; hence the proper digital artery and nerve are unharmed. The operation is limited only to the injured digit, which can reduce donor site morbidity.
