Removal of the plate is usually recommended for patients with comminuted humerus fractures, and retention of the plate may be considered if the patient is older. After a comminuted fracture of the humerus, immobilization with a plate is usually used to help the fracture heal in order to prevent displacement and other conditions. Removal of the plate from the humerus is often recommended because it can break during strenuous activity or cause infection if it is not removed. Surgery is also required to remove the plate, and in some older patients, the risk of reoperation is higher, so the decision to remove the plate is made on a case-by-case basis. The plates are mainly made of titanium alloy and have no significant effect on the body if they are not removed. If the plate is not removed, care should be taken to protect the fixed part of the plate to avoid complications such as infection. Patients with comminuted humerus fracture should go to the hospital regularly and ask the doctor’s opinion to decide whether to remove the plate according to the actual situation.
