The right distal ulnar radius fracture needs to be fixed first, either by external fixation in plaster or by internal fixation with surgical incision splints. Depending on the fixation method, the time and manner of activity are different, as follows: 1. If external fixation in plaster is adopted, the joint adjacent to the fracture will be fixed and cannot be moved, and the joint at the far end needs to be moved after fixation to prevent joint stiffness. The main activities are fist clenching training, 500-1000 times a day, and continuous elevation of the affected limb to promote the reduction of swelling symptoms.2. If incisional internal fixation is used, there is usually no need to use plaster fixation after surgery, and the patient can start light dorsiflexion and palmar flexion activities of the wrist joint about a week after surgery to promote the recovery of wrist joint range of motion and prevent wrist joint stiffness.
