Super Digit: More Than a Complicated Syndactyly

Super digits are a rare hand malformation, first described by Virchel Wood. Surgical intervention to try to make two fingers out of a super digit has been discouraged. Here, we present a variant of a super digit type IC2 and propose a revision of the characteristics in each super digit subtype. In our view, this adjustment in Wood's original description could facilitate the identification of super digits, which are a contraindication to syndactyly release.
