Finger Duplication/Polydactyly Newport Beach
Polydactyly or finger duplication is a congenital abnormality that can occur on any digit or finger. This condition occurs in 1 out of every 500 live births. The extra digit may have just soft tissue or it may also have a bony component. The extra digit occurs most commonly on the side of the hand with the little finger, less commonly on the thumb side, and very rarely within the middle three fingers. Finger duplication on the thumb side occurs more commonly in African-American male children.
To determine if there is any bony component to the duplicated finger, x-rays of both the hands or feet are needed to evaluate the bony anatomy for accurate diagnosis and surgical planning. Dr. Chen refers patients with more complicated polydactyly to a hand specialist.
