Some parents think that their children are still too young for surgery or that it is okay not to have surgery and want to wait until their children are older, but for children with floating thumb, it is important to have surgery as early as possible because these three aspects have a great impact on the child! 1, affect the hand function The thumb function occupies about 50% of the hand function, many floating thumb children have no metacarpal bone or only a little metacarpal bone, and the palm of the hand is connected to a loose skin tube, the child’s floating thumb basically no function, the child can not complete the palm, pinch, grip, clip and other actions. 2, affect the aesthetics of the hand Many children’s floating thumbs hang down, can swing at will, compared with the normal thumb, it looks abnormal, looks not a pair of normal hands, seriously affect the aesthetics of the hand. 3, affect the child’s psychology Many floating thumb children are not conscious when they are small, and children will not be too concerned, but as they grow, children will realize that their hands are not the same as others, and will develop an inferiority complex, not willing to let others see or pay attention to their hands, over time, will affect the child’s mental health. Therefore, I have been emphasizing that the surgery must be performed as early as possible at an age when the child can receive it. Together with the post-operative recovery exercises, the function and appearance of the child’s hand will be well improved, and the surgery done early will not have an impact on the child’s psychology.
