Surgical treatment of intraforaminal disc herniations at the L5-S1 level is technically demanding. The 2 most commonly used procedures involve either a medial or lateral ipsilateral approach and often require a partial or even complete facet resection, which may in turn result in vertebral instability and/or back pain, as well as, in some cases, a fusion or stabilization procedure. In this report, the authors present a new minimally invasive technique for the treatment of L5-S1 intraforaminal disc herniations. Using this technique, which involves tubular retractors and an operative microscope to approach the neural foramen from the contralateral side, the authors could easily visualize and remove the herniated disc material and perform a thorough microdiscectomy with minimal resection of osseous and ligamentous structures. To illustrate this new minimally invasive technique for the treatment of intraforaminal disc herniations at L5-S1, they describe the cases of 2 patients who underwent the procedure and in whom successful results were achieved.
L5 - S1节段椎间孔内椎间盘突出症的手术治疗在技术上要求较高。两种最常用的手术方法包括同侧内侧或外侧入路，通常需要部分甚至完全切除小关节突，这可能进而导致椎体不稳定和/或背痛，并且在某些情况下还需要进行融合或稳定手术。在本报告中，作者介绍了一种治疗L5 - S1椎间孔内椎间盘突出症的新型微创技术。使用该技术，即通过管状牵开器和手术显微镜从对侧进入神经孔，作者能够轻松地可视化并移除突出的椎间盘组织，并在对骨质和韧带结构进行最小程度切除的情况下完成彻底的显微椎间盘切除术。为了说明这种治疗L5 - S1椎间孔内椎间盘突出症的新型微创技术，他们描述了2例接受该手术且取得成功结果的患者病例。
