About this trial
In order to provide theoretical evidence for the comprehensive and standardized treatment of spinal metastases with pathological fractures and/or spinal cord compression, the investigators conduct this trial to investigate the efficacy and safety of IORT and postoperative SBRT in adjuvant treatment of metastatic spinal tumors after posterior decompression surgery by recruiting patients with spinal metastases who met the inclusion criteria, and randomly divided them into the following treatment cohorts: 1) decompression surgery + IORT (15-20 Gy, 20-50min); 2) decompression surgery and postoperative SBRT(30Gy, 5 fractions, 3 weeks).
