本文研究了位于手背第二、三、四及五掌骨头之间的岛状皮瓣。其血管蒂由富含血管的近侧指背处皮下脂肪组织组成。这些血管来自指掌侧固有动脉的背支及近侧指间关节周围血管网。以此蒂皮瓣可在近侧指间关节平面作旋转移位。由于该蒂较长,此皮瓣可用于覆盖中节及末节手指指背组织缺损。其主要优点在于 This article studies island flaps located between the second, third, fourth and fifth metacarpal bones in the back of the hand. The pedunculated pedicle consists of subcutaneous adipose tissue proximal to the dorsal portion of the vessel. These vessels originate from the dorsal and posterior interphalangeal arteries of the dorsal palmar artery. As a result, the pedicle flap can be rotationally displaced in the proximal interphalangeal joint plane. Due to the longer pedicle, this flap can be used to cover the mid-section and distal finger-dorsal tissue defects. The main advantage is that
