cross-finger flap

cross-finger flap

a flap designed on the volar or (more commonly) dorsal surface of one finger and used to reconstruct the opposing surface of an adjacent finger or the thumb of the same hand. The donor site is closed with a skin graft. In a second stage 2-3 weeks later, the pedicle is divided and the fingers separated.
