En Bloc Resection Versus Separation Surgery Combined With Radiotherapy for the Treatment of Spinal Oligometastatic Tumor.

Total enbloc resection (TES) is one of the most challenging surgeries in spinal surgery and a classic surgical method. It not only relieve spinal cord compression and delays tumor recurrence, but also prolongs patient survival, significantly reduces hand surgery trauma, and improves surgical safety. However, for cases with extensive tumor invasion, methods such as separation surgery should be used to relieve spinal cord nerve compression, rebuild spinal stability, and provide conditions for postoperative radiotherapy.
