Abductor digiti quinti opponensplasty
HA Wissinger and EG Singsen
Fifteen neurovascular pedicle transfers of the abductor digiti quinti to
the base of the proximal phalanx of the thumb were performed: seven for
laceration of the median nerve, seven for neurological disease, and one for
congenital absence of the thenar muscles. Fourteen of the transfers were
viable, and twelve gave excellent results. The three failures all had had
inadequate release of contractures of the thumb. This transfer offers the
following advantages over other opponensplasties: (1) an intrinsic muscle
with correct amplitude and direction of pull replaces intrinsic muscles;
(2) the tension of the muscle transfer is automatically correct; and (3)
the appearance of the hand after this procedure is superior to that after
other types of opponensplasty.
