What Causes Webbed Fingers and Toes? (Syndactyly)

by Stephanie Meadows
Sometimes children are born with a rare condition called syndactyly, where all fingers and toes are not individually formed. In other words, a person has “webbed” or joined fingers or toes, meaning the fusion of one or more digits on the hands or feet. Sometimes it is just the skin that is joined together, and in more severe cases the bones themselves are fused. This is not a lifelong condition, however, and many successful corrective surgeries have been performed for treating syndactyly.
