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.
手指近节指间关节以远侧的侧方软组织缺损的处理极具挑战性。由于缺损的长度，逆行同指岛状皮瓣的应用可能受到限制。相邻手指的损伤可能会排除使用异指岛状皮瓣。使用手部局部皮瓣会导致更广泛的软组织解剖，从而增加供区的发病率。我们介绍了同指背侧皮推进皮瓣的实施技术。皮瓣的蒂部基于指动脉穿支的背侧分支；因此，适当的指动脉和神经未受损。手术仅限于受伤的手指，这可以减少供区的发病率。
