Transforaminal Percutaneous Endoscopic Decompression for Lower Thoracic Spinal Stenosis.

Abstract：

OBJECTIVE:To explore the effect and safety of transforaminal percutaneous endoscopic decompression for lower thoracic spinal stenosis. METHODS:We reviewed 6 patients receiving transforaminal percutaneous endoscopic thoracic decompression for sympathetic symptoms in the lower extremities. Pre- and postoperative Frankel grade and Japanese Orthopaedic Association scale (JOA) score, Oswestry Disability Index (ODI) score, and visual analog scale (VAS) scores of back and lower extremities were also evaluated and recorded. Wilcoxon signed-rank test was performed for statistical analysis. RESULTS:All 6 patients completed the follow-up. Mean follow-up was 12.6 months. Frankel grade in all patients improved to normal at the third month after operation. JOA scores significantly increased from 4.4 (range, 3.5-5.0) preoperatively to 5.5 (range, 5.0-6.5) postoperatively, to 6.5 (range, 6.0-7.0) at 3 months, to 6.6 (range, 6.2-7.0) at 6 months, and to 6.6 (range, 6.2-7.1) at 12 months (P < 0.05). ODI scores significantly decreased from 71.2 (range, 65-78) preoperatively to 50.2 (range, 45-60) postoperatively, to 30.3 (range, 25-40) at 3 months, to 12.2 (range, 0-20) at 6 months, and to 10.2 (range, 0-15) at 12 months (P < 0.05). VAS back scores decreased from 7.8 (range, 7.0-9.0) preoperatively to 6.9 (range, 6.0-7.5) postoperatively, to 3.3 (range, 3.0-4.0) at 3 months, to 2.3 (range, 2.0-3.0) at 6 months, and to 1.9 (range, 1.5-3.0) at 12 months (P < 0.05). VAS lower extremity scores decreased from 8.7 (range, 8.0-9.0) preoperatively to 3.0 (range, 2.5-3.6) postoperatively, to 1.1 (range, 0.5-1.3) at 3 months, to 0.9 (range, 0.2-1.2) at 6 months, and to 0.3 (range, 0.1-1.0) at 12 months (P < 0.05). Four patients reported excellent results and 2 reported good results at the last follow-up. CONCLUSIONS:Percutaneous endoscopic transforaminal thoracic decompression is effective and safe in settling lower thoracic spinal stenosis.
