Regional first web flap used to cover the amputated stump of the thumb

Abstract

The regional first web flap is a distally-based flap that is raised from the radiodorsal aspect of the metacarpophalangeal joint of the index finger towards the dorsal first web, and used to cover a thumb amputation. The advantage of this flap over the conventional cross-finger flap is that is gives a thicker and hairless flap with no skin graft to the donor site. Mobilisation of the joints, including the metacarpophalangeal joint of the index finger, can also be maintained during the immobilisation period between two stages.
