If your baby or child has been born with a webbed hand or conjoined fingers (syndactyly), we share your concern. Please know that at Boston Children's Hospital, we will approach your child’s treatment and care with sensitivity and support—for your child and your whole family.

Please note: while syndactyly can affect a child’s toes as well as fingers, this section will focus mainly on syndactyly of the fingers, since the condition poses more complex challenges for hand-and-finger use than for foot-and-toe use.

What is syndactyly

If your child has syndactyly, it means that his fingers and/or toes are webbed or joined, and that the condition was present at birth. Syndactyly is a fairly common congenital defect that often runs in families. At Boston Children’s, it’s one of the most common congenital hand problems that we treat.

It affects both hands (bilateral) about 50 percent of the time. Syndactyly most often occurs between the middle and ring fingers.
