There are finger preservation options for floating fingers, and there are two types of finger preservation options, a metatarsal reconstruction and a hemimetacarpal bone graft reconstruction. The biggest difference between the two methods is that metatarsal reconstruction requires the foot to be moved, whereas hemimetacarpal graft reconstruction does not require the foot to be moved. Nowadays, we do more metacarpal bone graft reconstruction, the operation is divided into two phases, the first phase to build the skeleton, the second phase to rebuild the function. The outcome of floating finger surgery is related to functional exercises, so parents must emphasize on functional exercises. When guiding the child to perform functional exercises, parents need to note that not every child is very cooperative in the early functional exercises, some children will be more resistant, so parents must not be in a hurry when guiding the child to perform functional exercises, the thumb function should be established slowly. Parents must not be in a hurry when guiding their children to do functional exercises. Thumb function should be built up slowly. Usually, we should find out the child’s favorite toys, and let the child move the thumb by himself, so that when the child slowly realizes that the thumb can be used, he will be more and more cooperative, and the recovery of the thumb function will be better. For the treatment of floating thumb, surgery is not the goal, but to improve the function is the goal, with a relatively small cost to get more function, this is the goal of our doctors, and I believe it is also the hope of parents.
