The distally based posterior interosseous island flap for the coverage of skin loss of the hand.

Eight patients with skin coverage of the hand by the distally based posterior interosseous island flap (DBPIIF) are presented. The first web was reconstructed in 6 and the volar and dorsal aspect of the hand in 2 patients. Primary closure of the donor sites has always been possible. An echo Doppler examination is indicated to verify the presence and size of the vessel and the direction of its flow. The dissection of the vascular pedicle, however, is frequently quite complex and time consuming. To better appreciate the cosmetic aspect of the DBPIIF and its donor site, a random study has been undertaken to compare this flap with the radial forearm and the groin flap and their corresponding donor sites. Females have more often preferred the groin flap, whereas doctors preferred the DBPIIF. Reliability, a good aesthetic result at the donor site, and the preservation of the main vessels of the hand are the specific merits of the DBPIIF.
