Over the years, we have come into contact with many parents of children with floating bunions. Some parents know a lot about floating bunions, including methods such as bunionization of the index finger, while some parents are relatively unfamiliar with floating bunions and use words such as floating bunion and hovering bunion when describing their baby’s condition, and also write one of the treatments for floating bunions as bunionization of the index finger in text consultations. Whether parents know about floating bunions or not, one thing is undeniable: the vast majority of parents do not want to show thumb bunionization, but rather want to keep the floating bunion down. This is because when a baby’s thumb is completely floating, he or she can’t do anything and has problems coordinating the movements of both hands. For example, babies have trouble peeling bananas, so it makes sense to keep the floating thumb. It is not realistic to save the bunion without damaging it at all, but the method we are using now is a less damaging method – hemi-metacarpal bone graft reconstruction. Compared with taking the bone from the foot, it is more advantageous to take a part of the second metacarpal bone to reconstruct the first metacarpal bone, because it is very troublesome to take the bone from the foot, and it is also troublesome to take care of the patient after the operation, and taking the bone from the foot will have a greater or lesser impact on the child, while taking the second metacarpal bone doesn’t involve the foot of the child, so the aftercare of the operation is relatively simple, and the growth and development of the second metacarpal bone will not be affected. Therefore, we are now using half metacarpal bone graft reconstruction to treat floating bunions.
