Any surgery is risky. Humerus plate removal is relatively risky after a rigorous preoperative assessment, the main risk being the possibility of injury to the radial nerve. After the first internal fixation of the plate, there will be a large amount of localized scar formation. The scar may encase the radial nerve, the plate and the humerus, therefore, when the plate is removed in the second surgery, the scar must first be separated. When separating the scar, there is a possibility of damaging the radial nerve. After damaging the radial nerve, the patient’s sensation and function of the affected limb may be affected. After the plate is removed, attention should be paid to the local hygiene of the incision, keep the incision dressing clean and dry, and avoid being waterlogged, etc., so as to avoid infection. At the same time, pay attention to rest to avoid exertion, appropriate exercise, regular review to the hospital, under the guidance of the physician treatment.
