Abstract
BACKGROUND CONTEXT
Lumbar foraminal stenosis or extraforaminal stenosis is a common cause of spinal cord radiculopathy. Recently, several authors have introduced an endoscopy-based spinal surgery technique.
PURPOSE
The study aimed to introduce far lateral approach of biportal arthroscopic technique using 30° arthroscopy for foraminal decompression of L5-S1.
STUDY DESIGN
Technical note.
PATIENT SAMPLE
12 consecutive patients.
OUTCOME MEASURES
The leg VAS with modified Macnab criteria was measured.
RESULT
The leg VAS improved from VAS 7.5 to 1.8.
CONCLUSION
Far lateral approach of BASS with 30° arthroscopy is an alternative method that can decompress foraminal stenosis minimally invasively.
摘要
背景
腰椎椎间孔狭窄或椎间孔外狭窄是脊髓神经根病的常见原因。最近，几位作者介绍了一种基于内窥镜的脊柱手术技术。
目的
本研究旨在介绍使用30°关节镜的双门关节镜技术经远外侧入路对L5-S1椎间孔进行减压。
研究设计
技术说明。
患者样本
12例连续患者。
观察指标
采用改良Macnab标准测量腿部视觉模拟评分（VAS）。
结果
腿部VAS评分从7.5分改善至1.8分。
结论
采用30°关节镜的双门关节镜技术经远外侧入路是一种可微创减压椎间孔狭窄的替代方法。
