Rehabilitation training after fracture can be carried out through the following aspects: 1. Muscle exercise. Because of long-term inactivity or external fixation or internal fixation after fracture, the muscles will atrophy at this time, and functional muscle exercises should be carried out so that after the fracture is well, the activity is not weak. The common method is to raise the leg to 20-30 degrees, the whole lower limb should be tense, each time insist until you can not insist, a group of 20 exercises, 2-3 groups per day, muscle function will not atrophy, will even gradually recover. 2, joint function exercise. After the fracture, often may need to fix the joint, then the joint will appear stiff, and even limited activities. Once the fracture is stabilized, early functional exercises can be performed, such as flexion and extension, rotation, these functional exercises are also important for future recovery. In addition, proprioception can also be exercised because proprioception is a person’s own reflex that coordinates the body during movement, and after a fracture, this reflex is reduced, so it is also important to exercise.
