The purpose of this report is to show how our anatomical findings have influenced the design of the dorsal homodigital adipofascial turnover arterial flap to the thumb. Thirty-six thumbs from 18 fresh cadavers were dissected at the FSr A Moulin Laboratoire (Paris, France) between January 1998 and March 1999. All branches of the proper digital artery (PDA) were identified. During the clinical study, from 2002 to 2008, 12 patients with dorsal thumb skin defects were treated with adipofascial turnover flaps. The dorsal branches of the PDA typically emerge at the level of the metacarpophalangeal and interphalangeal joints, 10 mm apart from the joint line. Based on the anatomical study, the flap could be designed predictably and reliably. The main advantages of dorsal adipofascial turnover flaps include their simplicity; the possibility of a one stage procedure; avoiding the use of tissue from elsewhere on the limb/body; minimal donor-site deformity; and avoidance of damage to the volar digital arteries.
