While radiation therapy is a cornerstone of treatment, the role of spine surgery is evolving, fueled by advances in surgical techniques and radiation modalities such as stereotactic body radiation therapy (SBRT). This review examines the evolving role of spine surgery in MSC management, focusing on separation surgery, surgical innovations, and future directions. The treatment paradigm for MSC shifted with the advent of SBRT, which delivers high-dose precision radiation, improving local control even in radioresistant tumors. This advancement enabled the adoption of separation surgery, a technique aimed at creating a safe margin between the tumor and neural structures without extensive tumor resection, followed by SBRT to achieve tumor regression. Separation surgery reduces morbidity, shortens operative times, and achieves comparable local control rates to traditional corpectomy procedures. Innovations like minimally invasive surgery, stereotactic navigation, and cement-augmented instrumentation have improved surgical safety and outcomes. Emerging technologies, such as machine learning for predictive modeling and augmented reality for surgical navigation, hold potential for improving decision-making and procedural accuracy. Spine surgery remains integral to MSC treatment, especially for high-grade metastatic epidural spinal cord compression and mechanical instability. Integrating advanced technologies and multidisciplinary collaboration is key to optimizing patient outcomes. Comprehensive, patient-centered strategies addressing both oncological and mechanical aspects can improve survival and quality of life for patients with MSC.<\/jats:p>","DOI":"10.31616\/asj.2025.0042","type":"journal-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T01:56:45Z","timestamp":1758247005000},"page":"176-190","update-policy":"https:\/\/doi.org\/10.31616\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Spine
