Figure 2 A 47-year-old female patient with a bone mineral density of −0.5. (A) Axial, coronal, and sagittal 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) Axial, coronal, and sagittal CT images obtained after revision surgery demonstrate screw retention with cement surrounding the L5 screw in the same patient. * The image shows the cement around the L5 screw.
