549 Foot Syndactyly: Operative Management, Postoperative Webspace Splinting, and a Retrospective Review of Cases Across 15 Years at a Tertiary Plastics Centre

Abstract Aim Syndactyly of the foot is a common congenital abnormality, with an estimated prevalence 1 in 2,000. While thought to be more than hand syndactyly, there considerably less discussion syndactyly literature. We describe our operative approach and postoperative technique for splinting silicone moulds reduce webcreep complication. sought further characterise nature of, outcomes for, cases managed at centre. Method performed retrospective analysis paediatric centre over last 15 years. Results 47 patients (52 primary repair operations), involving 75 webspaces were identified (80.0% simple 1.3% complex, 18.7% not specified). 54.7% incomplete (21.3% complete, 24.0% The second webspace was most commonly involved (57.3%). Median age first operation 47.5 months. Of documented follow-up, 24.1% developed Complications included (13.8%), keloid (5.2%) hypertrophic scarring, graft loss (3.4%), infection overgranulation (1.7%), clinodactyly suture granuloma (1.7%). ‘V-shaped’/’triangular’ interdigitating local flaps. There no difference rates between FTSG STSG repairs. Conclusions Webcreep remains complication one parents must suitably informed about. This work adds relatively small body internationally describes method help post-operative contracture.
