Floating bunion can be preserved down without indication bunionization, and now the method we use is half metacarpal bone graft reconstruction. After surgery, through certain functional exercises, the baby can do a lot of movements, such as writing, holding chopsticks, unscrewing bottle caps, etc., as well as grasping tiny things, such as mung beans, red beans, grains of rice, and so on. Although it can be a little difficult to play the piano or the violin, there is a big difference between having no function in the thumb and having a function in the thumb. Some parents come to the clinic and ask if they can do it like a normal finger. As doctors, we share the same mentality as the parents, we all want our babies’ thumbs to function and look relatively good. However, floating thumbs are a severe form of thumb dysplasia, and it is very unlikely that they will return to look exactly like normal thumbs after the surgery, so we doctors will do our best to perform the surgery, and at the same time the parents will have to spend time to help their babies with their functional exercises, which will give them a better outcome.
