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

Abstract

We report a case of painful and disabling anterior acetabular bone metastasis treated with bipolar radiofrequency ablation and cementoplasty. Due to the high risk of complications related to the proximity of the femoral neurovascular structures with a direct approach, we successfully performed a retrograde transpubic approach under combined CT and fluoroscopic guidance. In the present report, we describe this approach detailing its indications, advantages, and the technical tips to achieve a safe and satisfactory procedure.

“…Further, its complications include higher infection rates, including pharyngeal infections and meningitis, injury to vertebral arteries, and cerebrospinal fistulas. The transoral approach is not useful for lower cervical vertebrae from C3-C7 (11)(12)(13). The transpedicular approach is also associated with the risk of vertebral arteries (13).…”
