This little boy then entered the clinic and sat silently on the stool by himself, and at the parent’s gesture, the child hesitantly put out his hand. When I asked him how his hand was working, he whispered that it was fine, but he couldn’t hold much. A lot of older children are like this, other people look at the hand feel particularly inconvenient, but they have gotten used to it. The child’s mother said that when the child was very young, they took the child to see a doctor, but at that time there was not too good a solution, so for so many years they tried to earn money to go. The child’s hand can be operated on and there is value in the surgery, what is the value? First of all, the appearance of the child’s hand will be better after we do the surgery. In addition, after splitting the thumb and separating the joined fingers, the child’s hand will have a greater range of dominance so that both appearance and function can be improved. When separating the joined fingers, we usually try to separate them at the same time, because one separation is less painful for the child, and two surgeries are more painful and time-consuming for a child of this age.
