The ulnar digital artery perforator flap: A new flap for little finger reconstruction - A preliminary report

An ulnar digital artery perforator flap was used for little finger reconstruction. The flap has a reliable blood supply, being perfused by a constant sizeable perforator. This paper describes a study of a cadaveric dissection with methylene blue dye that was conducted to prove the rationality and reliability of the blood supply. The position of the perforator is confirmed intraoperatively by an exploratory incision before committing to the distal incision. The flap used to cover the flexor aspect of the little finger in three cases yielded positive results. To our knowledge, a digital artery perforator flap of this nature is unprecedented. We propose to call this flap the B.J. Flap after our institute.
