First of all, floating bunions can definitely be treated, and there are many ways to treat them. For example, removing the original floating bunion and doing bunionization. Later on, we slowly developed the technique of reconstructing the first metacarpal bone by taking half of the metatarsal bone from the foot, i.e., metatarsal reconstruction technique. At first, it was done without vascularization, but we found that the chance of complication was relatively high, and later on, it was done with vascularization, but the trauma of the operation would be bigger and the appearance would not be good. In fact, whether it’s vascularized or not, as long as the bone is taken from the foot, the child can’t bear weight for three months after the operation, and the foot is permanently damaged, so he can’t run or jump strenuously. So now we don’t take the bones of the foot, but use the semi-metacarpal bone graft reconstruction technique, take part of the bone from the second metacarpal bone to rebuild the first metacarpal bone, it won’t move the foot, just need to take care of the hand on the line, the care is relatively simple. Newborns cannot have floating bunion surgery right away. In the past, when we used the metatarsal bone reconstruction surgical program, we required that the child not be too young for surgery. We now use the hemi-metacarpal bone graft reconstruction technique, the child’s operation age can be advanced to about 6 months – 1 year old, this time is exactly the stage of the child’s thumb function establishment, the child’s thumb function establishment will be relatively smooth, so we think that this period of time is better.
