[{"role": "system", "content": "Polydactyly or polydactylism (), also known as hyperdactyly, is a congenital physical anomaly in humans, dogs, and cats having supernumerary fingers or toes. Polydactyly is the opposite of oligodactyly (fewer fingers or toes). In humans/animals this condition can present itself on one or both hands. The extra digit is usually a small piece of soft tissue that can be removed. Occasionally it contains bone without joints; rarely it may be a complete functioning digit. The extra digit is most common on the ulnar (little finger) side of the hand, less common on the radial (thumb) side, and very rarely within the middle three digits. These are respectively known as postaxial (little finger), preaxial (thumb), and central (ring, middle, index fingers) polydactyly. The extra digit is most commonly an abnormal fork in an existing digit, or it may rarely originate at the wrist as a normal digit does. The incidence of congenital deformities in newborns is approximately 2%, and 10% of these deformities involve the upper extremity. Congenital anomalies of the limb can be classified in seven categories, proposed by Frantz and O\u2019Rahilly and modified by Swanson, based on the embryonic failure causing the clinical presentation.\n"}, {"role": "assistant", "content": "Ever heard of polydactyly or polydactylism?
