Small finger polydactyly may vary from only additional skin presence to double fifth finger.
The valid criteria for selection of the finger that will be excised is to protect the best developed finger same as the thumb polydactyly. To tie the skin extension part with a rope and to provide to fall by itself is a method which is very popular in the public. These small parts include vascular structures that are bounded to the hand. When they are tied up, circulation will be destroyed and they may cause infection development. Sometimes, they may cause bleeding that is not expected during auto-amputation. Therefore this method should not be applied.
