Dorsal digital perforator flap for reconstruction of distal dorsal finger defects.

Three patients are presented in whom defects of the distal part of the dorsum of the finger were covered with a rotation flap or V-Y advancement flap based on a single perforating branch of the digital artery running from the volar to the dorsal side. This method is useful for the reconstruction of the distal dorsal region of the fingers, because the flap is more mobile, has a smaller skin island and is less invasive compared to the previous flaps. This type of flap conforms to the concept of a perforator flap arising from the main artery.
