Background

The biportal endoscope-assisted unilateral foraminal approach is an option for various foraminal pathologies. Lumbar interbody fusion is the standard treatment for foraminal stenosis because both direct and indirect neural decompressions can be obtained.

Method

We used the biportal endoscopic technique for extraforaminal lumbar interbody fusion (BE-EFLIF) and have described the steps, with discussion regarding the indications, advantages, possible complications, and ways to overcome complications.

Conclusion

BE-EFLIF achieves direct neural decompression of lateral spinal canal under endoscopic visualization. It achieves indirect neural decompression using a large footprint lordotic interbody cage, while preserving the lumbar posterior arch as much as possible.

我该怎么做？双孔内镜技术辅助椎间孔融合术。

背景

双端口内窥镜辅助的单侧孔眼入路是各种孔眼病理的一种选择。腰椎椎间融合术是椎间孔狭窄的标准治疗方法，因为可以获得直接和间接的神经减压。

方法

我们使用双端口内窥镜技术进行椎间孔间椎体间融合术（BE-EFLIF），并描述了步骤，并讨论了适应症，优点，可能的并发症以及克服并发症的方法。

结论

在内窥镜下，BE-EFLIF实现了对外侧椎管的直接神经减压。它使用较大的脊柱前凸椎间融合器实现间接神经减压，同时尽可能保留腰椎后弓。
