About syndactyly

Syndactyly is a disorder in which a child's fingers are fused or webbed when they are born. Syndactyly affects both hands in around half of all children (bilateral). Syndactyly most commonly affects the fingers. It can also affect the toes, but not as frequently.


A baby's hands develop in the shape of a paddle during pregnancy and then divide into individual fingers. This happens extremely early in pregnancy, around the sixth to eighth week. If two or more fingers do not split at this period, syndactyly occurs.
Syndactyly is a condition that typically runs in families. Syndactyly is inherited by 10 to 40% of syndactyly children from their parents.


Surgery to separate the linked fingers is used to treat syndactyly. When your child is between the ages of one and two, he or she will most likely have this procedure.
