After removing the internal fixation plate from the radius, the local bone strength decreases, and the local bone strength becomes the weakest part of the anterior wall, and radius fracture still occurs when subjected to violence, and it needs to increase the strength through bone contouring at a later stage, and gradually return to the normal bone condition. Therefore, on the one hand, it is necessary to avoid re-fracture after surgery, that is, to avoid falling down again with the hand supporting the ground, and to avoid torsional violence of the forearm, which can cause re-fracture. On the other hand, it is also necessary to actively carry out the functional exercise of the forearm, through the use of the forearm, exercise to achieve the enhancement of the radial bone strength. Therefore, after removing the radial plate, it is necessary to prevent re-fracture as well as to strengthen the exercise to obtain functional recovery.
