Their clinical outcomes were evaluated with visual analog scale (VAS) leg pain score, Oswestry Disability Index (ODI), and MacNab's criteria. The outcome of motor deficitis was evaluated with the Medical Research Council (MRC) grade. Completeness of decompression was documented with a postoperative magnetic resonance imaging (MRI) and computed tomography (CT) scan.<\/jats:p><jats:p>\n          Results\u2003A total of 40 lumbar levels of 37 patients were operated, VAS score of the leg improved from 7.7\u2009\u00b1\u20091 to 1.9\u2009\u00b1\u20090.6 (p\u2009&lt;\u20090.0001). ODI score improved from 74.7\u2009\u00b1\u20096.5 to 25.4\u2009\u00b1\u20093.49 (p\u2009&lt;\u20090.0001). Motor weakness improved significantly immediately after surgery. The mean MRC grade increased to 1.97, 3.65, 4.41, and 4.76 preoperatively, at 1 week, at 3 months, and at the final follow-up, respectively, and all the patients with foot drop and cauda equina syndrome symptom recovered completely. One patient with great toe drop recovered partially to MRC grade 3. Mean follow-up of the study was 13.3\u2009\u00b1\u20096.1 months. According to MacNab's criteria, 30 patients (80.1%) had good and 7 patients (18.9%) had excellent results. Three patients required revision surgery.<\/jats:p><jats:p>\n          Conclusions\u2003Minimal nerve root retraction during full-endoscopic spine surgery is safe and effective for treatment of the impending neurologic deficit. We could achieve a thorough decompression of the affected nerve root with acceptable clinical outcome and minimal postoperative morbidity.<\/jats:p>","DOI":"10.1055\/s-0041-1725955","type":"journal-article","created":{"date-parts":[[2021,7,8]],"date-time":"2021-07-08T22:37:21Z","timestamp":1625783841000},"page":"135-142","source":"Crossref","is-referenced-by-count":1,"title":["Full-Endoscopic
