title: A versatile method for reconstruction of finger defects: reverse digital artery flap.
abstract: Four types of the reverse digital artery flap--standard, extended, and innervated standard and extended--were developed for 52 finger defects. The arising pattern of the dorsal branch which was included in the innervated flap was studied and classified in cadaver dissections. Topographically, the described "Lai's line" is a useful guide to locate the underlying digital artery. Refinements in flap design and surgical technique resulted in favourable functional and cosmetic results. The average two-point discrimination of the reconstructed fingertip was 6.8 mm and 3.9 mm in the noninnervated and innervated flaps, respectively. This versatile flap is an ideal and reliable option for one-stage reconstruction of various finger defects.
