The duration of cast fixation for a distal radius fracture is usually required until 6-8 weeks, which is about 1.5 to 2 months. After the fracture has been fixed in a cast, it is generally important to go to the hospital for a review of the film during the 1st week of post-injury fixation. This is because at this time the swelling and ecchymosis of the limb subsides and the cast may fail and needs to be fixed again, otherwise the cast loses its fixation effect. It is like wearing a pair of shoes that are one size too big. Then, during the process of cast fixation, X-ray examination is needed to confirm whether there is any fracture displacement, and if there is displacement, the patient should be treated promptly. Generally, after 6 weeks, an X-ray will be taken to confirm the healing of the fracture, and then the cast can be removed or protected with a simple splint, and the patient will be instructed to perform functional exercises. In general, the distal radius fracture should be fixed for 6-8 weeks and the patient should be instructed to perform functional exercises.
