BACKGROUND
Large spacers offer numerous advantages such as higher fusion rates and lower subsidence rates. However, due to the anatomical constraints of the approach, the use of large spacers in biportal endoscopic transforaminal lumbar interbody fusion(BE-TLIF) necessitates an additional incision and special instruments for spacer implantation leading to less frequent use.
METHODS
This study has refined several techniques within BE-TLIF. We insert the cage and impact the cage transverse with a special design instrument in the same working portal. This allows for the use of large spacers during BE-TLIF procedures without the need for an auxiliary cage-inserting incision.
CONCLUSION
The technique is a straightforward, safe, and minimally invasive method for inserting large cages in the treatment of lumbar instability.
背景
大的椎间融合器具有诸多优点，如更高的融合率和更低的沉降率。然而，由于双入路内镜下经椎间孔腰椎体间融合术（BE-TLIF）入路的解剖限制，大的椎间融合器的使用需要额外的切口和特殊的器械来进行融合器的植入，导致其应用不那么频繁。
方法
本研究对 BE-TLIF 中的几项技术进行了改进。我们在同一个工作通道中插入椎间融合器，并使用特殊设计的器械横向敲击椎间融合器。这使得在 BE-TLIF 手术中可以使用大的椎间融合器，而无需辅助的椎间融合器插入切口。
结论
该技术是一种简单、安全、微创的方法，用于治疗腰椎不稳定症时插入大的椎间融合器。
