When a bone fracture occurs in a foot bone trauma, the first step must be to apply a cast brake, and the foot must be elevated at the initial stage of braking, which will help the swelling of the foot to subside. Because the blood in the foot is easily returned when the foot is elevated, the swelling subsides more quickly. If it is clear that there is continuous bone scab at the fracture end, the cast can be removed and the foot can be gradually put on the ground for weight-bearing. Generally, if the fracture scab grows abundantly and the fracture line is blurred or disappears, the fracture has reached clinical healing.
