Syndactyly is a condition in which a person is born with fingers and/or toes that appear fused together. This condition affects about one in every 2,000 to 3,000 live births. It can be passed down in families and is occasionally associated with congenital (at birth) syndromes. The fusing may only affect part of the finger or extend the entire length.
Surgical treatment involves separating the fingers and/or toes, most often around 18 months of age.
