Concurrent fingerless implant surgery can be done when the child is about 6 months old. What are the problems if done late? First, the development of the fingers will be affected. If the child’s fingers are not released as early as possible, the child’s fingers will not be able to grow and develop well; second, the child’s mental health will be affected. Some children are more cheerful and do not have a special psychological burden because of the finger merging, but some children are relatively sensitive and feel that their hands are different from other children, so they do not want to take their hands out. The other day, there was a child with a finger parallel, a little girl, who didn’t hide her hand, but she used her right hand to cover her left finger. So parents must pay attention to the child’s psychological problems when looking at the problem of the child’s syndactyly, and operate as early as possible, and if there are special circumstances, they should also pay attention to the child’s emotions to avoid the negative impact of the syndactyly on the child’s mental health.
