For calf fracture, if the fracture is not obviously displaced, conservative treatment is carried out, and cast immobilization is usually carried out for about eight weeks. If the fracture line of the fracture end is blurred and there is continuity of the bone scab through, the cast can be removed and partial weight-bearing functional exercise can be started, and weight-bearing walking can be allowed after three months. If the fracture is displaced and requires surgical cut-and-replace and plate-and-screw fixation, it usually takes about six weeks. The fracture line begins to blur, and the continuous scab passes through the fracture end before the partial weight-bearing functional exercise of the calf is started, and weight-bearing is generally prohibited for calf fractures within six weeks. The reason is mainly due to the calf local soft tissue is weak, the blood supply relative to the trunk position of the blood supply is poor, so the calf fracture after the need for full weight-bearing time, usually need three months.
