Thumb reconstruction using congenital syndactylised toes in a child with transverse arrest of digits

An absent thumb with transverse arrest of digits and multiple toe syndactylies is an uncommon occurrence. Surgical options are limited and hence treatment may not be standard. We report a case whereby microsurgical transfer of syndactylic second and third toes for thumb reconstruction was performed for an 18-year-old boy with thumb absence and multiple congenital deformities of the fingers and toes.
