Pre-irradiation Vertebroplasty in Patients With Spine Metastases Candidates for SBRT vs SBRT Alone: Increased Early Pain Relief
The goal of treating metastases is to preserve stability and neurological function while reducing pain. The actual standard of care is stereotaxic body radiation therapy (SBRT) alone in non-surgical patients. The added value of vertebroplasty to SBRT is not well documented in the literature, nor whether performing vertebroplasty before radiotherapy treatment leads to a reduction in the rate of fractures and post-SBRT pain.
