According to our observation, if the child is younger, say around 3 months or 6 months of age, and is subjected to orthopedic surgery for the removal of multiple fingers, the child’s retained fingers will gradually grow with age. By the time he reaches adulthood, his fingers will be closer in size to normal fingers, with no obvious or particularly significant differences. On the other hand, if an adult or older child undergoes polydactyly, we find that the growth rate of the fingers is slower, which means that the fingers are more set, and the chances of the fingers growing again after the surgery are small. Therefore, we advocate that orthopaedic polydactyly be performed when the child is about 3-6 months old.
