It depends on the position of the steel plate, the size of the steel plate, the number of nails, whether there are steel screws and so on. Leg surgery, thighs and calves are definitely different, both thighs, and the cost of the upper, middle and lower segments is different.
There are many things here. I suggest you take the film to several hospitals for detailed consultation before making a decision. Dismantling the steel plate is not an emergency operation.
