Six-fingered boys can have finger deformities treated surgically. Six fingers, also known as polydactyly, are often present along with short fingers and syndactyly, and are common in the thumb and little finger. Surgery is often recommended to remove the paracubital finger and preserve the digit to restore the appearance and function of the hand. Surgery is often recommended after the age of one year. The earlier the surgery is performed on a child after the age of one year, the better the restoration of the hand’s appearance and function. There are many types of polydactyly, and it is necessary to determine the paracallosal and orthodactyly before surgery. Care should also be taken to ensure that the removal is complete and to avoid any residual defects. Postoperatively, it is necessary to prevent infection, change medication regularly, prevent collision, and at the same time, it is necessary to carry out rehabilitation exercises as early as possible under the guidance of the doctor, so as to facilitate the recovery of the function and appearance of the fingers.
