A father of a baby with a floating thumb said that when the baby was born, he was particularly confused because he and his mom didn’t have any problems with their thumbs, but the baby’s thumb was problematic, and at that time, the doctor said that the baby’s thumb should be useless. As parents, although it was hard to accept, they didn’t think in a pessimistic direction, but searched on the Internet, hoping to find a solution. After learning the information, the baby’s father walked into my office with some questions. Q: When can the floating bunion hemimetacarpal bone graft reconstruction surgery be done? A: Whether or not a baby can have a hemimetacarpal graft reconstruction surgery depends mainly on the width of the second metacarpal bone. In our experience, a one-stage surgery can usually be done at 6-8 months of age. Q: What is the approximate time span between Stage I and Stage II surgery? A: About four and a half months. The nail will be removed about three months after the Stage I surgery, and then the bone will be ready for Stage II in another month and a half. Q: Can the second stage surgery be done locally? A: Floating thumbs are special and local doctors do not know much about the first stage of the surgery, so the second stage of the surgery has to be done in our area. Q: What should I do if my baby likes to eat his hands and feels that the skin between his thumb and palm is getting longer and longer? A: Parents don’t need to intervene if their babies eat their hands or have normal activities, but they should pay attention to the protection in normal times, for example, don’t get entangled by threads when wearing clothes.
