The clinical symptoms of plate rejection after fracture surgery are mainly as follows: First, pain and swelling. The local pain and swelling of the plate after fracture surgery will be caused by the damage to the soft tissues and the release of metal ions, which will usually increase gradually, especially after the fracture heals and the plate screws become loose, the symptoms are more obvious. Secondly, if the plate is close to the joint, it will lead to joint pain and restricted joint movement, and the function of the joint will also be affected to a certain extent. Therefore, the plate should be removed promptly once the rejection reaction occurs after fracture surgery to avoid serious adverse consequences and also affect the health of the patient.
