For babies with floating fingers, we generally recommend surgery between the ages of 6 months and 1 year because this time period coincides with the stage when the baby’s thumb begins to establish function and it is better to keep the floating finger down at this time. How do we preserve the baby’s floating finger? The floating finger is attached to the palm of the hand by only one pituitary, and there is a risk of being strangled off if it is accidentally entangled by a thread, so it can be considered very fragile. For such a thumb, we now mainly use the hemipalmar bone graft reconstruction technique, the surgery is divided into two stages, firstly, we take part of the bone from the baby’s second metacarpal bone to reconstruct the first metacarpal bone, so that the thumb has a better appearance. 4-6 months later, we will do the second stage of surgery to reconstruct the function of the thumb, so that it can move, so that the appearance and function of the thumb are both available. After a period of functional exercise, your baby will be able to use the thumb to do things such as hold a pen to write, hold large objects with strength, etc. The more you use your thumb, the more flexible it will become.
