What are the diagnostic criteria for loosening a screw?

The diagnostic criteria for loosening developed by X-ray include the radiolucent area (thicker than 1 mm) around screw [ 4, 5, 6, 7, 8, 9] and the “double halo” [ 4, 10] defined as the presence of radiolucent area and radiopaque rim at the same X-ray.
