We have talked about the treatment options of floating thumb for many times, for floating thumb, now there are three treatment options to choose from, the first one is bunionization, which is a more traditional treatment option, the thumb function is not bad after it is done, but the disadvantage is that the child is left with only four fingers, which is unacceptable to many parents, not only Chinese parents can’t accept it, but also many foreign parents can’t accept it either. The floating thumb can be preserved, and there are two options for preservation, one is metatarsal bone grafting to rebuild the metacarpal bone, and the other one is hemimetacarpal bone grafting to rebuild the metacarpal bone, which is the hemimetacarpal bone grafting option that we are using now. Why did you think of doing a hemimetacarpal graft? Because after metatarsal grafting, the child can’t bear weight immediately, can’t stand, and has to wait for recovery before bearing weight, which is a big pressure for parents, and many parents think that the child’s hand is not good enough, and if the foot is not good enough, it’s hard for them to accept it. The floating thumb hemimetacarpal bone graft reconstruction requires two surgeries, and many parents do not know why it is necessary to do two surgeries and what each surgery is for. In the first surgery, we have to rebuild the bone, because without the bone, we can’t move it, and if we put a tendon on it without support, the thumb is still floating, and it’s useless, so we have to rebuild the bone first. Once we have a better metacarpal bone, we then rebuild the function and the stability of the joint.
