Patients with ankle fractures can place the foot in the following ways while sleeping:1. If the ankle fracture is simple and the displacement is not obvious, it can be externally immobilized by manipulating the reduction cast or splint, and the ankle can be continuously elevated away from the heart plane while sleeping, which not only brakes the ankle, but also promotes the subsidence of the local swelling, which is conducive to the smooth healing of the fracture.2. If the ankle fracture is a complex fracture, such as comminuted fracture. Usually, it is necessary to use the internal fixation of the cut-and-replace plate screws. After fixation, the stability of the fracture end can be fully guaranteed, and the patient does not need external fixation when sleeping. After a short period of elevation, the swelling subsides and the fracture can be placed normally, with no special requirements for foot position, as long as it is not subjected to stress. Therefore, ankle fractures should be placed according to different treatment methods and different types of fractures.
