Floating bunions do not improve as babies get older. If left untreated, the bunion may grow, but it will not function any better and will remain suspended and unusable. The only way to treat floating bunions at present is through surgery. There are three main types of surgery to treat floating bunions: bunionization, metatarsal reconstruction, and hemimetacarpal bone graft reconstruction. Bunionization is more traditional. Although it can give the affected hand the function of a thumb, it does not preserve the five fingers. It involves removing the thumb directly and transferring the index finger to the thumb position to be used as a thumb, and the child will only have four fingers forever after the surgery. Compared to thumb bunionization, metatarsal reconstruction and hemi-metacarpal bone graft reconstruction techniques can save the child’s thumb, and there will be different degrees of functional and cosmetic improvement after the surgery. The biggest difference between them is that the sites of the bone extraction are different, so there are some differences in the subsequent impacts and results. Metatarsal reconstruction is the reconstruction of the first metacarpal bone from the foot, there is a certain chance of bone resorption and necrosis, and once it occurs, you will have to face a second operation. Because the foot is the main weight-bearing area, bone removal from this area will have some impact on the child’s ability to bear weight for at least three months after the operation, and the child can only lie down or sit, which will be more cumbersome for parents to take care of. Semi-metacarpal bone grafting technique is to reconstruct the first metacarpal bone from the second metacarpal bone, which greatly reduces the chance of bone resorption and necrosis, and the operation does not involve any other parts of the body, so the postoperative care is relatively simple. After the surgery, the appearance and function of the child’s hand is quite good. As long as the functional exercises are in place, the child’s hand can basically meet the daily needs of writing, screwing bottle caps, or grasping some large objects with great force.
