“A picture says a thousand words” – Novel teaching model for interdigitating flaps in syndactyly

Syndactyly is a congenital deformity of the hand resulting in the fusion of two or more digits. The most common surgically corrective techniques use interdigitating ulnar and radially based Z-flaps. Such interdigitating flaps can be challenging to convey to patient, parent and junior surgeon alike. The authors propose a simple and educationally effective method of demonstrating such flaps in syndactyly, utilising a single 10 x 10cm sheet of DuoDERM (ConvaTec). This method allows three dimensional demonstration of the flaps, can be easily cut with scissors, mobilised and will then adhere into place with appearances and handling properties similar to skin.
