Abstract:
Objective:The aim of this study was to observe possible risks for traversing root injuries during endoscopic transforaminal lumbar interbody fusion (endo-TLIF) via an accessory portal.
Methods:Twenty patients were recruited for this study according to our inclusion and exclusion criteria. An accessory portal was made 3 cm caudal to the working portal, and a 30°/4.3-mm endoscope was utilized to observe possible risks for traversing root injuries throughout the entire process of disc preparation and cage implantation.
Results:The traversing root was observed via the accessory portal throughout the process of disc preparation and cage implantation in 20 patients. Endo-TLIF was shown to be a suitable method for decompression and cage implantation as it provided a sufficient working space and window. No cases of traversing root injuries were observed in our study.
Conclusion:Endo-TLIF was found to be a suitable method for disc preparation and cage implantation. Our observations showed that endo-TLIF is a safe method for decompression, disc preparation, and cage implantation.
