Hello, no, this situation belongs to polydactyly. The plastic surgery time of this deformity should be between 6 months and 2 years after birth, which is the best age for hand plastic surgery. The reason why the operation is performed before the age of 2 is mainly conducive to the improvement of the function of the child's hand. When he grows up, the appearance of the whole hand will be more beautiful, especially the multi-fingers, which can also make the child have a healthy and normal psychology and personality. If they are sensible, they will find that their hands are deformed, which will inevitably cause trauma to their young hearts. Therefore, we must operate as soon as possible.
