Syndactyly affects the aesthetics and function of the affected hand, and in severe cases, it can substantially reduce the function of the hand. If the fingers are not separated as soon as possible, the deformity of the fingers will worsen with age and may lead to low self-esteem, which is very unfavorable to the child’s physical and mental development. If your child has a syndactyly, we recommend splitting the fingers at around 6 months of age, as long as the child is healthy and weighs 6kg. Why this time? 1. When the child is small, the bones are softer, the healing ability is stronger, and there is more room for growth, so the post-operative effect will be more obvious. 2. Children grow very quickly, so if the fingers are not separated at the right time, the deformity will be aggravated. If the child is the middle, ring and little finger together, these three finger body length difference is large, they will interact with each other, resulting in deformation of the finger joints, this situation and then the operation will be more complicated, and the child is also very unfavorable.
