The versatile Adani's flap for fingertip coverage: indications and case reports.
Heterodigital pedicle flaps have 2 possible patters of vascularization: anterograde flow (Littler) or reverse flow (Adani). The Adani's flap uses the Y-V pedicle lengthening principle. The flap is raised from the adjacent uninjured finger based on the digital artery. The common digital artery is ligated and a long pedicle is formed from the 2 converging digital arteries to supply a reverse flow flap. Four patients with severe fingertips injuries were submitted to surgical treatment with the Adani's flap. All flaps integrated and provided skin coverage. The Adani's flap has a long vascular pedicle that allows a wide arch of transposition. An easier vascular dissection in a site distant from the trauma which evolves a higher diameter digital artery and proximal interphalangeal arterial system promotes a high survival rate and good functional results. Adani's flap is a reliable technique for severe fingertip injuries.
