Figure 1 Coronal reconstruction from computed tomography on bone windows, demonstrating the presence of bilateral destructive lesions in the acetabula as well as additional iliac lesions.

Figure 2 A series of planar images from a cone-beam computed tomography acquisition. (A) Vertebroplasty needles are present in the supra-acetabular regions bilaterally. (B–E) A series of images in different obliquities are provided, acquired periodically during injection of radiopaque cement. The image was degraded by the patient's body habitus.

Figure 3 Reconstructions obtained from cone-beam computed tomography data acquisitions. (A) Coronal reconstruction from left hip, showing the needle in position (which was introduced via an anterolateral approach), with cement in the supra-acetabular area. (B) Parasagittal reconstruction of the left hip, showing the lateral position of the needle and cement distribution. (C) Axial reconstruction, showing the cement distribution in the right acetabulum. (D) Paracoronal reconstruction, showing cement in the right acetabulum before needle removal. Some additional cement was subsequently injected.
