A student sent me a video of a clip from the Song dynasty, probably about a newborn princess who had her extra fingers cut off with scissors by her own mother because she had six fingers on her left hand. Let’s not talk about the plot, at that time I guess that was the only way to deal with it, for the deformity of the hand, after the growth of extra fingers to cut it off was one of the most direct methods that could be taken at that time, but direct cutting off will have a lot of problems, there will be infections in the early stage, the usual common bacterial infections or tetanus, which are all possible to occur. And there’s a good chance of deformities in the later stages, including scarring contractures of the wound, etc. Of course different types of polydactyly lead to different consequences, but these situations are entirely possible. From our modern point of view, we should not recognize the problem of polydactyly in such a simple way, for example, it is a very one-sided understanding to say that polydactyly can be directly cut off because polydactyly is not like an extra branch of a tree cut it off and that’s it. In the process of removing polydactyly, not only the part that is cut off, but also the part that is left should be considered. Therefore, we should have a better understanding of this disease, and we should realize that this disease is not only about growing an extra finger, but also about the shape, structure and function of the finger that we want to keep. Therefore, when we carry out surgery for polydactyly, we should not only cut it off, but also minimize the complications that may occur in the future, not to say that they will not occur at all, but we should try to control the complications as far as possible within the scope of our ability, which is also some of the better medical care that modern medicine can provide to babies, rather than just a simple matter, cut off anything that has more than one finger. Instead of a one-sided treatment plan, it should be more personalized and fine-tuned to solve the problem of baby’s polydactyly. The hand has two layers of function, the first is aesthetic, the hand is the second face, of course, scar less appearance will be better, this is a basic requirement; the other is the function, the hand is a very important labor tool to distinguish between us humans and other animals, so that the function of the hand is very important. Therefore, from these two considerations, we have to do a good job in polydactyly, especially the thumb polydactyly, the thumb occupies about 50% of the function of the hand, so for thumb polydactyly, we absolutely can’t deal with it arbitrarily. We have seen too many cases where this is done arbitrarily with particularly undesirable consequences, and this is something that parents should be aware of.
