Computed tomography-based navigation system-assisted surgery for primary spine tumor

The objective of the study was to examine the utility of O-arm navigation-assisted surgery for a primary spine tumor. A prospective study was performed in 18 consecutive patients who underwent O-arm navigation-assisted surgery for a primary spine tumor at our hospital between 2014 and 2017. Data were collected for patient demographics, tumor details, surgery performed, and postoperative complications. The proportion of patients with a primary spine tumor; complications in the navigation procedure and equipment; complications in resection; local recurrence; radiological evidence of mechanical failure in cases where implants were used for reconstruction; and mortality were evaluated as outcomes. The cases included osteoblastoma (n = 4), Langerhans cell histiocytosis (n = 3), aneurysmal bone cyst (ABC), chondrosarcoma, osteoid osteoma (n = 2 each), and giant cell tumor (GCT), pigmented villonodular synovitis (PVNS), hemangioma, sarcoidosis, and plasmacytoma (n = 1 each). There were no intraoperative complications related to the navigation procedure or equipment, and this procedure was not abandoned after it had been started in any case. There were 12 posterior, 3 anterior, and 3 posterior and anterior approaches, and 7 instrumented surgeries. There was no evidence of screw misplacement and mechanical implant failure, and no local recurrence in any patients. O-arm navigation-assisted surgery improves safety and oncological results in patients with primary spine tu...
