Advancements in Surgical Management of Periacetabular Metastases: Emphasizing Minimally Invasive Techniques

This review aims to summarize the evolution of surgical techniques for periacetabular metastatic cancer, assess their strengths and limitations, and clarify the corresponding indications. We conducted a comprehensive literature review on periacetabular metastatic cancer, summarizing surgical techniques involving both open and minimally invasive approaches. Additionally, we evaluated the indications for different minimally invasive techniques and proposed potential combinations of these techniques. Our review underscores the benefits of minimally invasive surgery, including reduced surgical trauma, improved patient mobility, lower complication rates, and expedited recovery times, facilitating earlier initiation of systemic cancer therapies. These techniques show substantial potential for broader application in the future. Despite the historical reliance on open surgery as the standard treatment, minimally invasive approaches are emerging as a promising alternative, particularly for managing osteolytic metastases around the acetabulum. This review provides insights into the optimal integration of these techniques, aiming to support evidence-based clinical decision-making and improve patient outcomes.
