Your fracture has not completely healed, and there is no obvious callus growth on the outside. The fracture is still shifting. It's better to put the lateral film on it, because there is obvious displacement and overlap from the frontal film (you are both in the frontal position). If there is displacement on the lateral radiograph, it is necessary to operate as soon as possible, and continue conservative treatment if the lateral radiograph is fine. As for shortening 1cm, it should not be a big problem, and I am afraid that the position of the fracture is not good, which will lead to the slow development of the affected limb. You can turn to another film.
