The abductor digiti minimi flap: its use in revision carpal tunnel surgery.

One of the few muscles or myocutaneous flaps in the hand available to cover soft-tissue defects without compromising significantly the hand's function and appearance is the abductor digiti minimi muscle. A technique that harvests the abductor digiti minimi flap with a small skin island from the hypothenar eminence allows direct closure of the skin following ADM transposition and makes it possible to directly monitor the blood supply to the muscle. This skin island is much smaller than others previously reported.
