Extreme lateral interbody fusion (XLIF) has been widely used for minimally invasive anterior lumbar interbody fusion (ALIF), but an approach to L5-S1 is difficult because of the iliac crest. In the current study, we present 2 cases using minimally invasive oblique lateral interbody fusion (OLIF) of L5-S1. The patients showed foraminal stenosis between L5 and S1 and severe low back and leg pain. The patients were placed in a lateral decubitus position and underwent OLIF surgery (using a cage and bone graft from the iliac crest) without posterior decompression. Posterior screws were used in the patients. Pain scores significantly improved after surgery. There was no spinal nerve, major vessel, peritoneal, or urinary injury. OLIF surgery was minimally invasive and produced good surgical results without complications.
极外侧椎间融合术（XLIF）已广泛应用于微创前路腰椎椎间融合术（ALIF），但由于髂嵴的存在，L5-S1节段的手术入路较为困难。在本研究中，我们展示了2例采用L5-S1微创斜外侧椎间融合术（OLIF）的病例。患者表现为L5和S1之间的椎间孔狭窄以及严重的腰腿痛。患者取侧卧位，接受OLIF手术（使用椎间融合器和取自髂嵴的骨移植），未进行后路减压。患者使用了后路螺钉。术后疼痛评分显著改善。未发生脊神经、大血管、腹膜或泌尿系统损伤。OLIF手术具有微创性，手术效果良好，无并发症发生。
