Colgajo libre interóseo posterior para reconstrucción de mano: A propósito de un caso

Abstract

Hand coverage is a challenge for plastic surgeons, because there are many therapeutic options available. The distally based posterior interosseous artery flap is one of the most useful elections for reconstruction of this defect. However, we can find problems in dissecting the flap due to an inconstant vascular anatomy. Anatomical variants are well known and they can be of two types: the absence of the distal anastomosis with the anterior interosseous artery and the hypoplasia or aplasia of the middle third of fhe posterior interosseous artery, with a relatively high rate of partial flap loss which may result in coverage failure. In order to prevent an unsuccessful flap harvest, we have used an interosseous free flap for a woman with a 7 x 7 cm defect in the dorsum of her left hand.
