Dorsal pentagonal island flap to reconstruct post-burn interdigital web

INTRODUCTION: This study reports the use of a dorsal pentagonal island flap for post-burn webbing contracture, in which the islanded flap is harvested from the burn scar tissue. METHODS: Fourteen dorsal pentagonal island flaps were harvested in seven patients with post-burn webbing. Each flap was selected by examining the scar tissue donor using a modified Vancouver scar scale. Modification from the basic design was made according to the density of the donor scar tissue and the metacarpophalangeal joint movement. RESULTS: All the flaps survived with normal abduction of the affected fingers. Modification of the flap design needed adjustment by assessing it through flexion and extension of the metacarpophalangeal joints. There was no incidence of web creep after two months to one year of follow-up. CONCLUSION: Dorsal pentagonal island flap shows promising results as an alternative for reconstructing post-burn webbing.
