With this in mind, we combined OLIF with spinal endoscopic technique to achieve a solid fusion and an adequate decompression after one operation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This is a technical note. The theoretical basis and operation process of this technique were introduced, and consecutive cases were retrospectively collected. Consecutive patients diagnosed with monosegmental severe LSS (L4\/5) and underwent oblique lateral endoscopic decompression and interbody fusion (OLEDIF) from January 2018 to February 2020 were retrospectively collected. Clinical outcomes were assessed by claudication distance, Visual Analog Scale (VAS), and Oswestry Disability Index (ODI) scores. Secondary indicators included operation time, operative blood loss, and postoperative complications.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ten patients were selected for the OLEDIF procedure. They were five women and five men ranging in age from 49 to 75\u2009years (mean age of 63.9\u2009years) and in BMI from 25.4 to 30.2 kg\/m<jats:sup>2<\/jats:sup> (mean BMI of 27.5 kg\/m<jats:sup>2<\/jats:sup>). The preoperative claudication distance was 160.00\u2009\u00b1\u200968.96 m (range 70\u2013250 m), which was significantly extended on the 3\u2010month and 1\u2010year follow\u2010up (1020.00\u2009\u00b1\u2009407.70 m and 1040.00\u2009\u00b1\u2009416.87 m, respectively). The preoperative VAS score of back pain and radiating leg pain was 5.50\u2009\u00b1\u20090.97 (range 4\u20137) and 6.40\u2009\u00b1\u20090.97 (range 5\u20138). The score on postoperative month 3 was 1.60\u2009\u00b1\u20090.52 (range 1\u20132) and 1.20\u2009\u00b1\u20090.79 (range 0\u20132), and the 1\u2010year follow\u2010up score was 1.90\u2009\u00b1\u20090.74 (range 1\u20133) and 1.60\u2009\u00b1\u20090.70 (range 1\u20133), respectively. The preoperative ODI was 72.23\u2009\u00b1\u20096.30 (range 64.4\u201382.2), the 3\u2010month follow\u2010up ODI was 31.12\u2009\u00b1\u20094.20 (range 24.4\u201335.6), and the 1\u2010year follow\u2010up ODI was 29.33\u2009\u00b1\u20095.92 (range 20.0\u201337.8). Compared with the transforaminal lumbar interbody fusion (TLIF) in the literature, the operation time was not prolonged (189.3\u2009\u00b1\u200932.5\u00a0min vs. 214.9\u2009\u00b1\u200960.0\u2009min) but the amount of blood loss decreased significantly (113.3\u2009\u00b1\u200926.7\u00a0ml vs. 366.8\u2009\u00b1\u2009298.2\u00a0ml). No complications were found except one case presented with dysesthesia of the left leg. Imaging results showed good fusion without cage subsidence during 1\u2010year follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>OLEDIF can achieve complete ventral decompression of the spinal canal and solid fusion of the lumbar spine at one time.
