Regardless of the age group, functional exercise is a problem that patients need to overcome on their own. Therefore, when dealing with a young baby with floating bunions, how to properly guide him to do functional exercises is a very crucial point. After all, if the functional exercise is done properly, the postoperative result will be more satisfactory. Some time ago, a parent asked me if he should find a professional place to do post-surgical functional exercises after his baby has undergone reconstructive surgery for hallux valgus grafting. Actually this is not necessary, we prefer parents to guide themselves. Why? Because parents know their children better than others. Many babies are not reluctant to do functional exercises, but they don’t know how to do it. It is better to have a familiar person to guide them patiently. In the process of guiding parents should pay attention to two points, the first is to see what the baby likes, and the second is to encourage the baby in time, which is not just a simple correction, but to make the baby realize that the thumb can be used, so that the baby will slowly be willing to use the thumb, and accustomed to using the thumb. Parents can give the baby some toys, such as larger balls, or more slippery glass beads, etc. These toys can not be played with by the middle finger of the index finger, they will use both hands to pinch and grasp, which is a better phenomenon. Parents can also pay attention to the baby, try to give the baby some interesting toys, so that the baby can be in the process of play is very natural to do a good job of functional exercise.
