On the basis of good repositioning and fixation, the earlier the functional exercise, the better. It can promote blood circulation, reduce muscle atrophy, eliminate soft tissue swelling, prevent osteoporosis and accelerate fracture healing. 1.Early stage: within 2 weeks after the injury. You can make a fist, hang your arm and lift your shoulder to make the whole upper limb muscles contract and then relax. Move the shoulder on the affected side to prevent the shoulder stiffness caused by the wrist fracture that dares not move. If the elbow joint is not immobilized, you can also extend and flex the elbow joint. No movement of the wrist and no rotation of the forearm. 2.Middle term: between 2~6 weeks after the injury. At this time, the local swelling and pain disappear, and the fracture end is more stable due to fibrous healing and gradual increase of bone scabs. It is not easy to dislocate under the protection of splinting. In addition to the above exercise, increase the activity of the affected finger, so that the finger can be fully straightened and flexed. 3.Later stage: more than 4~6 weeks after the injury. At this time, the fracture is clinically healed and the external fixation is removed. Patients can further do the functional exercises of the fingers with the help of external Chinese medicine, based on the good function of the shoulder joint and elbow joint, and at the same time, add the functional exercises of the wrist joint until the function is restored. During this period, the patient can do some light work that he can do.
