Wide margin en bloc resection is becoming the trend for the treatment of primary spinal tumors. However, only few cases in the literature describeen bloc tumor resection including dural resection. We here describe a case of wide en bloc resection of a spinal osteosarcoma using spondylectomyanddural flap resection, followed by duraplasty repair. This was followed by adjuvant chemotherapy. At forty-two-monthsof followup, the patient was stable neurologically and free of disease radiologically. The clinical presentation, operative technique and related literature are reviewed.
