Graftless Syndactyly Release

Abstract

Syndactyly release aims to address skin deficits by resurfacing web spaces and sides of digits to allow independent digital motion while minimizing the risk of web creep and scar contractures. Conventional methods include the use of a dorsal and interdigitating flaps with full-thickness skin grafts. More recently, there have been several descriptions of “graftless” syndactyly release without skin grafts, thus avoiding a further (usually distant) donor site. However, the indications of when and when not to use these techniques remain unclear. In addition, the inevitable scarring from extra recruitment of local adjacent skin is perhaps underemphasized. In this article, we revisit the trilobed flap technique which serves to balance the amount of skin needed for resurfacing digits while minimizing local donor site scarring. The geometry and nuances of the flap inset are illustrated in detail to guide those embarking on this technique. The trilobed syndactyly release technique is a reproducible, safe, and reliable method for the release of simple syndactyly.
