Figure 1 A 50-year-old male patient with a bone mineral density of −2.2. (A) Coronal, sagittal, and axial computed tomography (CT) images of L5 obtained after the initial operation demonstrate a halo sign around the screw (star shows peri-screw halo ring). (B) Coronal, sagittal, and axial CT images obtained after revision surgery in the same patient demonstrate persistent L5 screw loosening (star shows peri-screw halo ring).
