The presence of distal intermetacarpal anastomoses between dorsal and palmar vascular networks makes it possible to raise distally-based cutaneous island flaps oriented along the axis of the dorsal metacarpal arteries. These flaps receive a reverse-flow vascularisation. Distal intermetacarpal anastomoses were found consistently in 35 hands from adult cadavers. The exact location of these anastomoses varied with the course of the dorsal metacarpal artery. Thus, island flaps can be raised consistently from the dorsal aspect of the hand and rotated around a distal intermetacarpal pivot. These flaps are suitable for covering the dorsal aspect of the proximal phalanx and the proximal interphalangeal joint.
掌背和掌侧血管网之间存在掌骨间远端吻合支，这使得沿掌背动脉轴方向掀起以远端为蒂的皮岛瓣成为可能。这些皮瓣接受逆向血流供血。在35例成年尸体的手部中均一致发现了掌骨间远端吻合支。这些吻合支的确切位置随掌背动脉的走行而变化。因此，可始终如一地从手背掀起岛状皮瓣，并围绕掌骨间远端枢轴进行旋转。这些皮瓣适用于覆盖近节指骨背侧及近端指间关节。
