ObjectiveTo examine effects of percutaneous endoscopic débridement and allograft via the transforaminal approach combined with percutaneous pedicle screw fixation as treatment for single-level thoracic tuberculosis.MethodsThis multicenter retrospective analysis included 75 patients with single-level thoracic tuberculosis who underwent percutaneous endoscopic débridement and allograft via the transforaminal approach combined with percutaneous pedicle screw fixation and were followed for >36 months between January 2012 and December 2014.ResultsFollow-up was 36-48 months (average 41.1 ± 2.2 months). Intraoperative blood loss was low (average 30.5 ± 7.9 mL), and bed rest time was short (average 1.5 ± 0.3 days). No recurrence was observed in all 75 patients. Except for 3 patients, almost all patients (96%) achieved grade I or II fusion in interbody bone grafting. Segmental Cobb angle was 13.5° ± 4.1° before surgery, 10.5° ± 3.7° immediately after surgery, and 11.7° ± 3.9° at 36 months of follow-up. All patients achieved complete recovery of neurologic function (American Spinal Injury Association grade E), including 15 patients with spinal cord injury (American Spinal Injury Association grade D) before surgery. The visual analog scale and 36-Item Short-Form Health Survey scores significantly improved at 1, 3, 12, and 36 months of follow-up. No complications related to internal fixation occurred within the follow-up period; complication rate was 9.0%.ConclusionsMedian follow-up clinical experience with percutaneous endoscopic débridement and allograft via the transforaminal approach combined with percutaneous pedicle screw fixation indicates that the technique is safe, effective, feasible, and minimally invasive.Copyright © 2018 Elsevier Inc.
