The privileged donor site of the foot is a well-recognized warehouse for spare parts particularly adaptable for composite tissue replacement of hand defects. Simultaneous microsurgical transfer of many of these parts is frequently performed. The ability to transfer these components on a common vascular leash as distinct yet dependent entities is another variation of this theme that enhances its flexibility. The extensor digitorum brevis muscle island and separate vascularized second metatarsal osteocutaneous flap represent one of many possible technical combinations of conjoined flaps based on the dorsalis pedis source vessel. The muscle portion of this flap provides any necessary soft tissue coverage. Sufficient dorsal foot skin is spared to allow primary closure of the foot, thereby minimizing morbidity in this notoriously difficult donor site.
足部的特殊供区是一个公认的“备用零件仓库”，特别适用于手部缺损的复合组织替代。许多这些组织部分常同时进行显微外科转移。将这些组织成分作为不同但相互依存的实体在同一血管蒂上进行转移的能力是该主题的另一种变化形式，增强了其灵活性。趾短伸肌肌岛和独立的带血管蒂第二跖骨骨皮瓣是基于足背动脉源血管的联合皮瓣众多可能技术组合之一。该皮瓣的肌肉部分可提供任何必要的软组织覆盖。足背保留了足够的皮肤，以便足部能够一期缝合，从而将这个 notoriously difficult donor site（此处可能有误，根据前文推测可能是“极其困难的供区”）的发病率降至最低。
