The general recovery time for ankle bone fracture is in three months. When the ankle bone fracture is fixed in a cast or brace, the lower limb should be elevated during the fixation period, which is conducive to blood return to the injury site and can quickly reduce pain and swelling. It is not allowed to walk with the cast on the ground during the fixation period, otherwise it will easily lead to external fixation failure, delayed fracture repair or deformity of the fracture. At six weeks of immobilization, X-rays can be taken, and if there is a clear passage of continuous bone scab at the ankle joint, it means that the fracture has initial stability. At this time, the cast can be removed and the patient can gradually walk with weight with the support of a double crutch, but the crutch should not be abandoned at this time, i.e., full weight bearing. At the end of three months, if the fracture is clinically healed, the patient can walk with full weight bearing.
