Rehabilitation training after fracture can be carried out according to the following methods: First, at the early stage after fracture fixation, due to the lack of sufficient stability of the fracture end, the static contraction and diastole of the muscles are the main focus at this stage, mainly to speed up the blood circulation, promote the swelling to subside and restore the blood supply to the fracture end, but it is usually difficult to completely control the muscle disuse atrophy, mainly because the affected limb cannot carry out normal weight-bearing. Second, the fracture is relatively stable after six weeks, at this time, resistance training should be the main focus, through the use of elastic bands or sandbags, resistance training of the limb, gradually increasing resistance, trying to restore muscle strength and intensity to the pre-injury level, but also to lay a good foundation for normal weight-bearing walking in the future.
