What is syndactyly?

Fingers together: It is condition found at birth in which the fingers share skin and sometimes bone and nail. I think the latin translation is actually together finger. There are essentially stuck together. It can affect any bordering digits and even rarely the thumb.

Syndactyly: Is a common congenital condition where webbing or attachments between fingers or toes persists until birth. During the development of a child in utero programmed cellular intructions lead to the separation of fingers and toes into distinct members. If something either genetic or familial or syndromic ( assocaited with other issues) interferes then the fingers/toes do not separate " normally".
