Polydactyly is a common congenital (at birth) condition in which a person is born with an extra finger or toe. This condition affects about one in every 1,000 live births and is often passed down in families. Usually only one hand or foot is affected. The extra digit can be located anywhere on the hand or foot. It is usually smaller and made up of soft tissue, though some can have bone and joints and be fully functioning.
Most extra digits can be removed with one, outpatient orthopaedic surgery. A cast or physical therapy may be needed after surgery.
