For osteolytic metastatic disease in the pelvis and acetabulum of patients with unpredictable and limited lifespans, first-line treatment focuses on targeting the primary cancer with anticancer drugs, osteoclastogenesis inhibitors, analgesics, and radiation therapy. Uncontrolled pain and progressive bone destruction refractory to these interventions often warrant surgical stabilization. Conventional open surgical procedures using metal implants or prostheses may provide immediate biomechanical stability but are associated with various complications without local cancer control. Outcomes of conventional open surgical reconstructive procedures depend on local cancer progression and progressive bone loss. Percutaneous cancer ablation and bone augmentation with polymethyl methacrylate cement alone often lack optimal internal fixation and integration with surrounding bone. The current literature demands a multipurpose minimally invasive surgical intervention that provides local cancer control, bone protection, and stabilization. An overview of new, alternative percutaneous procedure consisting of image-guided ablation, balloon osteoplasty, cement reinforcement, and internal fixation, which offers a minimally invasive percutaneous treatment option for patients with osteolytic metastatic cancers with the advantages of concurrent thermal necrotization of cancers, zoledronate-loaded bone cementoplasty, and surgical stabilization in an ambulatory surgery setting, is warranted. Early clinical results have shown that the ablation, balloon osteoplasty, cement reinforcement, and internal fixation is a safe and effective alternative solution for stabilizing and palliating osteolytic lesions in patients seeking new effective therapies in the era of rapidly evolving oncologic care.
