Degenerative spondylolisthesis is a common spinal pathology. Traditionally, spinal fusion is an accepted standard surgical treatment for listhesis. But fusion is a major intervention with its known pitfalls. With technological progression, minimally invasive spinal fusion (MISF) procedures are becoming mainstream. Percutaneous trans-foraminal endoscopic lumbar discectomy/decompressions (PTELD) without stabilization has many advantages over even a MISF for select group of patients. In this case report, we describe using a uniportal unilateral trans-foraminal approach (TFA) for stable listhesis with lumbar disc herniation (LDH) causing chronic bilateral radicular symptoms and back pain with acute exacerbation. Under local anesthesia, we used a flat entry for PTELD, which facilitates an approach to both disc sides ventrally and even dorsal aspect lateral recess decompression on the dominant ipsilateral side. No fixation was done. An excellent outcome is obtained immediately at 6 weeks and maintained at 39 months of follow-up. PTELD is worth considering as an intermediate procedure before fusion is offered in lateral recess stenosis in stable listhesis patients who have consented and understand the progressive cascade of spinal degeneration.

经椎间孔内镜下单眼减压治疗退行性腰椎滑脱：技术和病例报告

退行性脊椎滑脱是一种常见的脊柱病理。传统上，脊柱融合术是公认的李斯特菌手术标准。但是融合是已知缺陷的主要干预措施。随着技术的进步，微创脊柱融合术（MISF）成为主流。经皮经孔椎间孔内镜下腰椎间盘摘除术/减压术（PTELD）相对于某些患者，即使是MISF也具有许多优势。在本病例报告中，我们描述了使用单门单侧经椎间孔入路（TFA）进行稳定的腰椎滑脱合并腰椎间盘突出症（LDH），引起慢性双侧放射状症状和急性加重的背痛。在局部麻醉下，我们对PTELD使用了固定输入 这有利于接近椎间盘的两侧，甚至在同侧占主导地位的背侧面横向凹陷减压。没有固定完成。在第6周立即获得良好的效果，并在随访39个月时保持良好。对于已经同意并了解脊柱退行性进行性级联的稳定的硬皮病患者，PTELD作为融合术可用于外侧隐窝狭窄，值得考虑。
