Syndactyly (C0039075)

Definition (NCI) A congenital condition characterized by webbing between the fingers and/or toes, joining the digits together. In rare cases, the joining of the fingers or toes may involve bony fusion between the digits. Common causes include Down Syndrome and hereditary syndactyly.
Definition (MSH) A congenital anomaly of the hand or foot, marked by the webbing between adjacent fingers or toes. Syndactylies are classified as complete or incomplete by the degree of joining. Syndactylies can also be simple or complex. Simple syndactyly indicates joining of only skin or soft tissue; complex syndactyly marks joining of bony elements.
