The use of traditional open decompression alone in degenerative spondylolisthesis can lead to the development of postoperative spinal instability, whereas percutaneous endoscopic decompression can preserve the attachment of intervertebral muscles, facet joint capsules, and ligaments that stabilize the spine. The study’s aim was to determine clinical as well as radiologic outcomes associated with interlaminar percutaneous endoscopic decompression in patients with stable degenerative spondylolisthesis. For this study, 28 patients with stable degenerative spondylolisthesis who underwent percutaneous endoscopic decompression were enrolled. The clinical outcomes in terms of the visual analogue scale (VAS) and Oswestry disability index (ODI) were evaluated. Radiologic outcomes were determined by measuring the ratio of disc height and the vertebral slippage percentage using lateral standing radiographs. The average follow-up period was 25.24 months. VAS and ODI were significantly improved at the final follow-up. In terms of ratio of disc height and vertebral slippage percentage found no significant difference between the preoperative and postoperative periods. One patient underwent further caudal epidural steroid injection. One patient underwent fusion because their radicular pain did not improve. Interlaminar percutaneous endoscopic decompression is an effective procedure with favorable outcomes in selected patients with stable degenerative spondylolisthesis.

椎间盘穿刺内镜减压治疗退行性腰椎滑脱伴椎管狭窄的临床疗效

在退行性脊柱滑脱中单独使用传统的开放减压可导致术后脊柱不稳，而经皮内镜下减压可保留椎间肌，小关节囊和韧带的附着，从而稳定脊柱。这项研究的目的是确定伴有变性退行性腰椎滑脱的患者经层间经皮内镜减压的临床及影像学结果。在本研究中，纳入了28例经皮内镜下减压稳定的退行性腰椎滑脱患者。根据视觉模拟量表（VAS）和Oswestry残疾指数（ODI）评估了临床结局。放射学结果是通过使用侧位X光片测量椎间盘高度与椎间盘突出率的比率来确定的。平均随访期为25.24个月。在最后的随访中，VAS和ODI显着改善。在椎间盘高度与椎间盘突出率的比率方面，发现术前和术后期间无显着差异。一名患者接受了进一步的尾硬膜外类固醇注射。一名患者接受了融合术，因为他们的神经根疼痛没有改善。对于稳定的退行性腰椎滑脱症的选定患者，层间经皮内镜下减压术是一种有效的方法，其预后良好。在最后的随访中，VAS和ODI显着改善。在椎间盘高度与椎间盘突出率的比率方面，发现术前和术后期间无显着差异。一名患者接受了进一步的尾硬膜外类固醇注射。一名患者接受了融合术，因为他们的神经根疼痛没有改善。对于稳定的退行性腰椎滑脱症的选定患者，层间经皮内镜下减压术是一种有效的方法，其预后良好。在最后的随访中，VAS和ODI显着改善。在椎间盘高度与椎间盘突出率的比率方面，发现术前和术后期间无显着差异。一名患者接受了进一步的尾硬膜外类固醇注射。一名患者接受了融合术，因为他们的神经根疼痛没有改善。对于稳定的退行性腰椎滑脱症的选定患者，层间经皮内镜下减压术是一种有效的方法，其预后良好。
