The main goal of orthopedic surgery is to improve the appearance of the baby’s thumb to make it look like a normal thumb or close to a normal thumb, which is one of the goals of the surgery. Another goal is to establish a relatively good function, which is the ability to open the hand, so that the baby can establish abduction, palmarization, and flexion of the thumb. Of course there are very many types of polydactyly of the thumb, and they are also classified. Different deformities have different bases and appearances, and orthopedic surgery needs to be considered from both functional and cosmetic perspectives, but it is definitely necessary for the surgeon to improve the thumb through surgery, and it is impossible for the baby’s thumb to function soundly without surgery. What parents need to do is to let their baby have the surgery as soon as possible and to help their baby with the recovery exercises as explained by our doctors after the careful surgery, so that the baby can establish the function of the thumb as soon as possible.
