We report a case of digital revascularization in a child's small finger by using a digital artery from the adjacent uninjured digit. Reconstruction of a defect in the digital artery with a vein graft is technically challenging in a child and has a higher risk of failure due to anastomoses at 2 levels and possible size mismatch. We detail the technique of heterodigital artery transfer from the ring finger to revascularize the small finger with segmental loss of both digital arteries. This technique has not been reported previously and offers a simpler alternative to vein grafting in select situations.

Analysis of thumb pulp reconstruction based on different local flaps: A systematic review.
J Hand Microsurg
October 2024
School of Medicine, Pontifical Catholic University of Rio Grande do Sul, PUCRS, Porto Alegre, Brazil.
Background: The reconstruction of the thumb's pulp is challenging when considering that there is no consensus on which local flap will provide better prognosis and less financial impact. The aim of this study was to analyze the outcomes of the most used flaps for the trauma to the volar substance of the thumb, validating the main indications.
Methods: This systematic review adhered to PRISMA guidelines and electronic searches were conducted in multiple databases (MEDLINE/PubMed, Virtual Health Library, Embase and Scopus) with studies published in the last ten years - until April 2022.
Dorsal V - Y Advancement Flap for Lateral Finger Defect Based on Dorsal Skin Branch of Proper Digital Artery.

Managing lateral soft tissue defects, distal to the proximal interphalangeal joint, of the finger can be challenging. The use of antegrade homodigital island flap can be limited due to the length of the defect. Using a heterodigital island flap can be precluded by an injury in the adjacent fingers.

J Hand Surg Am
October 2024
Department of Hand and Foot Surgery, Clinical Medical College, Yangzhou University, Yangzhou, China. Electronic address:
Purpose: Modified heterodigital neurovascular island flaps and free lateral great toe flaps are dependable methods for treating thumb-tip defects with phalangeal bone exposure. We retrospectively analyzed and compared the details and results of the two methods.
Methods: This retrospective study included 25 patients with thumb injuries with phalangeal bone exposure treated between 2018 and 2021.
A systematic review of outcomes following hand reconstruction using flaps from the superficial palmar branch of the radial artery (SUPBRA) system.
J Plast Reconstr Aesthet Surg
January 2021
St Andrews Centre for Plastic Surgery, Broomfield Hospital, Court Road, Chelmsford CM1 7ET, United Kingdom.
Background: Flaps based on the superficial branch of the radial artery (SUPBRA) are indicated when homo- or heterodigital flaps are inappropriate, but glabrous or like-for-like reconstruction is required.
Aim: To systematically review the outcomes of hand reconstruction using SUPBRA flaps.
Methods: PubMed was searched for English-language articles studying SUPBRA flaps in November 2019.
Pedicled flap from the first dorsal branch of the proper palmar digital artery of the fingers: An anatomy study.

Service de chirurgie de la main - chirurgie plastique et reconstructrice de l'appareil locomoteur, centre chirurgical Emile-Gallé, CHU de Nancy, 49, rue Hermite, 54000 Nancy, France. Electronic address:
The pedicled flap from the first dorsal branch of the proper palmar digital artery (FBPPDA) of the fingers is an option for reconstructing digital skin defects. It has the advantage of being innervated by the dorsal branch of the proper palmar digital nerve (DBPPDN) associated with the artery. However, no studies on the anatomical variations of the neurovascular pedicle have been performed yet.
