Polydactyly

What is polydactyly?

Polydactyly is a condition in which a child has extra fingers or toes. It is one of the most common hand differences and often runs in families. The extra fingers/toes may be only soft tissue (which looks like extra skin), but some include bones as well.

What causes polydactyly?

Polydactyly occurs when a finger, thumb or toe splits in two – causing an extra one to form while the baby is in the mom's uterus before birth.
