Many parents are concerned about the optimal age for floating finger surgery. Since we have realized the treatment of floating finger with the Semi Metacarpal Bone Graft Reconstruction (SMRT Floating Bunion Reconstruction), we have successfully advanced the age at which a child can undergo the surgery to between 6 months and 1 year of age, which is also the optimal age for floating finger surgery, as the surgery is performed earlier and the child can establish thumb function earlier. Some parents have questions, “The earlier the surgery, the better, so wouldn’t it be better to have the surgery even earlier?” For children with floating fingers, the surgery should not be done too early. First of all, the child’s weight must meet the anesthesia requirements, he or she must not have heart disorders, and the width of the metacarpal bones must also meet certain standards. “How old is my child and can I still have a hemi-metacarpal bone graft reconstruction surgery?” Yes, there have been a number of older children who have had hemi-metacarpal bone graft reconstruction surgery, as well as 12 year olds. It’s just that, relatively speaking, the younger the child is when they have the surgery, the better their recovery will be, and the surgery for older children will have an impact on their learning and psychology, so that’s why we have always emphasized the need to have the surgery done as early as possible. Although we can do the surgery when the child is older, parents must pay attention to the fact that early surgery will not only help the child establish thumb function earlier, but also will not affect the child’s study and psychology, so the surgery should be done at the latest before the child goes to school.
