Syndactyly is a hand deformity where two or more fingers (or toes) are fused together. Polydactyly is a condition where the hand (or foot) has additional fingers/toes (most often the little finger/toe). These two conditions are the most common hand and foot conditions seen by pediatric plastic surgeons. While some can be treated non surgically, most require surgical treatment.
Syndactyly - The cause of syndactyly is when parts of the hand (either bone and/or tissue) fail to separate while the child is in the womb. Syndactyly is often an inherited family trait. There are two kinds where either the fingers are only fused by the tissue, or fleshy part, or the fingers are fused between the bones. When fingers are completely fused together it is called complete syndactyly.
Polydactyly - Polydactyly can be genetic, passed down in families, or can occur on it's own. The extra finger is usually smaller than the other fingers and abnormally developed. It could be made of skin and soft tissue or could include a bone and joint.
