Among the babies with floating fingers recently, the youngest one was a baby of two months old, and if I remember correctly, the baby was brought by his mother and grandmother. During the consultation, the mother said she had read a lot of my articles and asked if the younger the baby’s floating finger, the better. She hoped to solve the problem in the baby’s hand as soon as possible. The grandmother said that the baby mother is very heavy psychologically, often crying, the family is very worried about the baby mother. I can understand her feelings, and I have seen a lot of mothers with a heavy psychological burden during the clinic, but the smaller the baby’s floating finger surgery, the better, because the width of the second metacarpal bone is more critical when doing hemimelia reconstruction. So how many times do we have to do the floating finger surgery? There are many parents who ask this question. The floating finger usually requires two surgeries, one to give the bone and the second to rebuild the function. The two surgeries need to be done 4-6 months apart, usually about 4 months apart if the baby is young. Because hemimelia reconstruction is only done on the baby’s hand and does not involve the baby’s foot, post-operative care is still relatively easy and parents only need to follow medical advice to take care of their baby.
