The incidence of polydactyly is not low, about 1 in 1000. Polydactyly not only affects the appearance, but also affects the development of normal fingers and the social interaction and self-esteem of the affected child.
The purpose of surgery is to completely remove the redundant finger, prevent recurrence, reduce the impact on the rest of the fingers, and reconstruct the tendon and trim the flap to rebuild a finger with similar appearance and function to normal surgery. In principle, the earlier the surgery the better, but considering the risk of surgical anesthesia, it is generally recommended to operate after the age of 1 year and weighing 10 kg or more, so as to facilitate the reconstruction of the anatomical structure and function of the finger, obtain satisfactory results in appearance and function, and ensure the relative safety of the surgery.
