Kids with floating bunions, we now have a way to bail them out, how? There are two surgical options, one is to take the metatarsal bone from the foot, which is called half metatarsal reconstruction. The other one is to take the second metacarpal bone without moving the foot, which is called half metacarpal bone graft reconstruction. Currently, we are using half metacarpal graft reconstruction. Why don’t we use half metatarsal reconstruction? Because there are some problems with taking bone from the foot, one is that you can’t go down to the ground for at least three months after the operation, and you have to stay in bed, so it is very inconvenient for parents to take care of you; secondly, whether it is free bone grafting or anastomotic vascular grafting, there is a certain chance of graft resorption and necrosis. In the case of hemi-metacarpal bone graft reconstruction, the foot is not moved, and the child will have no problem running or jumping after the surgery, and the chance of bone resorption and necrosis will be greatly reduced. The surgery is usually divided into two phases, the first phase is to move the bone, and the second phase is to reconstruct the function, so that the thumb can function as a pair of palms, have some grasping function, and can also pinch some small objects. To put it simply, it is to build a house first and then do the renovation. There are a lot of cases in the popular science article on floating thumb, parents can refer to it.
