A few days ago, a child’s parents asked me for advice, the child’s right hand is congenital bunion deformity floating thumb, thumb basically has no function, the child’s parents said they have seen in the local, the doctor said that the child’s right hand floating bunion can not continue to develop, it is recommended that the direct surgical removal, and then show the finger to the position of the thumb, although the doctor said that the operation is simple and safe, but they can not accept the child’s right hand only four fingers, they They want their child’s fingers to be intact, and asked if there is any other way to do it other than bunionization of the demonstrative finger. Before the floating bunion surgery In the face of floating bunions, doctors in Europe and the United States are used to removing the floating bunion and then bunionizing it, which is difficult for many parents and children in China to accept. In addition to bunionization, we can also choose metatarsal reconstruction and metacarpal grafting reconstruction as a solution to the problem of floating bunions. Metatarsal bone reconstruction is a traditional surgical method that involves transplanting half of the third or fourth metatarsal bone (longitudinal) of the child’s foot into the affected hand to reconstruct the first metacarpal bone and the first carpometacarpal joint. However, the child who undergoes metatarsal bone reconstruction will need to wear a cast on the foot after the operation, and the child’s foot will not be able to put weight on it for three months, which requires that the foot will not be able to touch the ground for three months; at the same time, the operation time is longer, and whether it is free bone grafting or anastomotic vascularized bone grafting, there is a certain grafting At the same time, the surgery takes a long time and there is a certain chance of bone resorption and necrosis in both the free bone graft and the anastomotic vascularized bone graft. After Floating Bunion Surgery Metacarpal Bone Graft Reconstruction (SMRT Floating Bunion Reconstruction) is the newest surgical procedure that takes a portion of the child’s second metacarpal bone to reconstruct the first metacarpal bone. This way, the child’s foot will not be affected in any way, and the chances of bone resorption and necrosis are greatly minimized. What’s more, the child can undergo the surgery between the ages of six months and one year, which will help to establish the function of the bunion at a much earlier age. Both metatarsal and metacarpal bone graft reconstruction can be used to treat floating thumbs and preserve the thumb, but metacarpal bone graft reconstruction has multiple advantages over metacarpal bone graft reconstruction in solving the problem of floating thumbs in children. It avoids some of the impacts caused by bunionization and metatarsal reconstruction, and the post-operative care is relatively simple. Compared with the preoperative period, the postoperative appearance and functional recovery are more satisfactory, and more and more parents are now more willing to choose this new surgical method of preserving the five fingers.
