A parent asked: My baby has congenital thumb dysplasia and was diagnosed with drifting finger in the hospital. How old can my baby be to undergo reconstruction surgery for floating fingers? If a baby chooses to have metatarsal reconstruction surgery, the metatarsal bone will be taken from the child’s foot, and the foot will need to be fixed in a cast after surgery. In contrast, metacarpal bone graft reconstruction is performed on the baby’s hand only, and the baby’s foot is not affected in any way, and the baby can receive the surgery between the ages of 6 months and 1 year to establish bunion function earlier. Both metatarsal reconstruction and metacarpal bone graft reconstruction can preserve the child’s floating bunion, but many parents have the concern that the baby itself will have to undergo surgery for the floating bunion, and the hand is already carrying the injury, so if the bone is then taken from the foot, then the child’s foot will also carry the injury, and they worry that the child’s foot will be affected by this in the future. Therefore, more and more parents are willing to choose palmar bone graft reconstruction as a surgical option to treat their baby’s floating bunion.
