Currently, there are two types of bunion reconstruction orthopedic procedures used for the treatment of floating bunion, metatarsal reconstruction and semimetacarpal bone graft reconstruction (SMRT floating bunion reconstruction). However, I personally prefer the latter procedure for three reasons: 1) It will have less impact on the future of the child. Metatarsal reconstruction involves removing the bone from the foot to reconstruct the first metacarpal bone, which will leave a very obvious scar on the child’s foot after the surgery, which is not aesthetically pleasing. After the surgery, the child’s foot will be scarred, which is not aesthetically pleasing. Moreover, the child’s foot will be permanently damaged after the removal of the bone, and he or she will not be able to run or jump vigorously. On the other hand, half-metacarpal bone graft reconstruction is done from the second metacarpal bone to reconstruct the first metacarpal bone, and the whole operation is only carried out on the hand, which will not affect other parts of the body. Second, the care is relatively simple. Metatarsal bone reconstruction is to take the bone from the foot, the child can not bear weight for three months after the operation, can only lie down or sit, which is very difficult for the active age of the child, parents need to take care of the child at all times. On the other hand, half-metacarpal bone graft reconstruction technique is only performed on the hand, and the only thing you need to do is to pay attention to the affected hand after the surgery, so the care is relatively simple. Thirdly, after the surgery, the child’s thumb function can be established earlier. As long as the child’s weight is up to standard, the width of the metacarpal bone is suitable, and the child is healthy, the earliest time for the child to undergo surgery is 6 months to 1 year old. The earlier the surgery is performed, the earlier the child’s thumb function can be established.
