[0002] Medical imaging examinations such as X-rays, CT scans, and MRI scans all require obtaining clear and accurate images during the examination. Joints are parts of the human body that are frequently in motion. If a joint moves during the examination, motion artifacts will be produced. Using joint fixation devices can restrict the movement of the joint and ensure that the joint remains stationary during the scan, thereby obtaining high-quality, artifact-free, clear images that help doctors accurately determine the internal structure of the joint.
