Retrograde Transpubic Approach for Percutaneous Radiofrequency Ablation and Cementoplasty of Acetabular Metastasis

Figure 2

(a) Nonenhanced axial CT image demonstrates the entry point of the retrograde transpubic approach via the pubic tubercle (open arrow). (b)–(d) Anteroposterior fluoroscopic images show the needle guided through the superior pubic ramus toward the lesion (arrowhead) (b), the radiofrequency probe inserted coaxially (c), and the distribution of cement (d) at the end of the procedure.
