Single-stage posterolateral transpedicular approach for resection of epidural metastatic spine tumors involving the vertebral body with circumferential reconstruction: results in 140 patients

The PTA allows circumferential epidural tumor decompression and the placement of anterior and posterior spinal column instrumention. Immediate spinal stability is achieved without the use of brace therapy. This technique achieved a high success rate for pain palliation, neurological preservation, and functional improvement, while avoiding the morbidity associated with combined approaches.
