Early diagnosis, better imaging, and advanced treatment of cancer patients extend survival and increase the incidence of symptomatic spine metastases. The treatment algorithm for spine metastases has shifted to a more aggressive approach in recent years. Spine stereotactic radiosurgery (SRS) is a relatively new tool utilizing advanced imaging systems, planning software, image-guided localization, and intensitymodulated dose delivery. Radiosurgery of spine metastases yields high rates of pain-and tumor control, and offers both the patients and the treating physicians an effective noninvasive alternative. This review presents the indications and outcomes for SRS and describes current techniques.
