DORSAL PENTAGONAL ISLAND FLAP: A TECHNIQUE OF WEB RECONSTRUCTION FOR SYNDACTYLY THAT FACILITATES DIRECT CLOSURE

Abstract

Though many techniques have been described for the correction of syndactyly, current methods result in skin deficiency that requires skin grafting, especially at the finger bases. We discuss the technical aspects and document our experience with the dorsal pentagonal metacarpal island flap for reconstruction of the web commissure in a series of 12 patients (22 webs) with syndactyly of varying complexity. In appropriately selected cases, this technique can improve reconstruction of the web commissure, facilitating direct closure, minimising the need for skin grafts and offers the potential for continued growth. This reduces operative time significantly and simplifies post-operative wound care. In this series, all our cases healed primarily in two to three weeks with minimal donor site morbidity. There were no post-operative complications, although the prominent dorsal scar remains a concern. At an average follow-up of 33.7 months, no cases of contracture or web creep after correction were noted.
