A sixth finger on the hand is a congenital polydactyly, which is often seen in daily life. It is a congenital deformity of the hand and can be surgically removed. This surgery is very simple and not too expensive, and after the extra finger is removed, the hand remains in the normal state of five fingers, which is very convenient in daily work and life. If the patient agrees, the sixth finger can be removed if it is inconvenient to wear gloves or other aspects of life. The incision will be removed in a week or so and the patient will be fully recovered in half a month at most, just like a normal person. Therefore, the sixth finger can be cut out and it is very convenient for future life after it is cut out.
