Functional exercise method of humerus fracture 1.After repositioning and fixation, start to practice active stretching exercises of upper arm muscles, strengthen the squeezing pressure of both fracture ends on the longitudinal axis, prohibit upper arm rotation activities; practice passive and active flexion and extension of interphalangeal joints, practice wrist extension and flexion, practice fist clenching, finger extension and elbow joint activities. 2.Start shoulder and elbow joint activities (extension and flexion of the shoulder and elbow joints, rotation of the shoulder joint, and raising of the arms) in 2 to 3 weeks. 3.After the external fixation is released in 4-6 weeks, you can practice the shoulder joint activities comprehensively. Functional exercise method of ulnar radius fracture 1.After repositioning and fixation, you can start activities, initially practice upper arm and forearm muscle stretching and contraction activities, do hard fist clenching and full flexion and extension finger movements. 2.After 2 weeks, the local swelling will subside, and the activities of shoulder, elbow and wrist joints will be started, and forearm rotation is prohibited. 3.After 4 weeks, forearm rotation and pushing wall movements were started to produce longitudinal compression between the fracture ends. 4.In 7-8 weeks, when the X-ray shows that the fracture has entered clinical healing, the external fixation can be removed and the function of each joint can be fully exercised. Functional exercise method of clavicle fracture After local fixation, you should maintain the posture of lifting the shoulder, practice various activities of the hand, wrist and elbow joints and practice shoulder joint abduction and posterior extension, such as doing posterior extension and forked hands, but avoid doing shoulder anterior drive and inward movement. Functional exercise methods after upper limb scar contracture 1. Postoperative functional position: postoperative elbow in straight position, wrist in slightly dorsal extension position, metacarpophalangeal joint flexion 80°～90°, interphalangeal joint slightly flexed 5°～10°. 2.Elevate the affected limb, brake, and fix with splint or plaster support to prevent contracture and facilitate flap survival. 3.Functional hand exercise: After the stitches were removed 14 days after surgery, functional exercise was started under the guidance of exercise, joint mobility and muscle strength exercises were performed, passive and active flexion and extension of the interphalangeal joints were guided, and wrist extension and flexion were practiced. 4. Elbow exercise: Active exercises of flexion and extension, adduction, abduction and elbow function. The amount of force is appropriate to cause joint pain. 5.Muscle strength exercises: You can directly carry buckets or sandbags or use special muscle strength exercises to exercise to promote muscle strength recovery and make the muscles contract as hard as possible to cause fatigue, and then rest appropriately. 6, in the joint and muscle strength has a certain recovery, and into the work therapy, a variety of practical functional exercise, practice finger function, grip chopsticks, fitness ball exercises, the movement from simple to complex, step by step, and gradually increase the amount of activity.
