Ankle injuries that meet the indications for surgery usually require steel pins to immobilize the broken ends of the fracture, which varies from person to person. The main purpose of the nail in ankle surgery is to fixate and maintain the stability of the fracture, to promote the smooth healing of the fracture site, and to speed up the recovery of ankle joint function. If the ankle joint injury reaches the indication of surgery, it usually indicates that the fracture degree is more serious, which can not be solved by external fixation method only, and needs to be treated with surgery for internal fixation, usually using steel nails for fixation, and steel plate fixation if necessary. Fractures of the ankle include external ankle fractures, internal ankle fractures, and posterior ankle fractures. Posterior and medial ankle fractures are usually fixed with steel pins, while lateral ankle fractures are usually fixed with plates, depending on the patient’s individual condition. Nailing is a common fixation method in ankle surgery, and patients should actively cooperate with the doctor’s treatment to help promote the recovery of the ankle joint.
