Uniportal Full Endoscopic Posterolateral Transforaminal Lumbar Interbody Fusion.

Abstract

Uniportal full endoscopic posterolateral lumbar interbody fusion (FE-TLIF) has recently shown promising results. However, beginners may face challenges in mastering the technical skills required to overcome the learning curve for a more efficient and safer procedure. The goals of this study are to provide a detailed FE-TLIF procedure and provide a step-by-step explanation of all methods, as well as to use written text to describe key techniques and precautions for ensuring a safer and more efficient procedure. We present a case of L4-L5 degenerative spondylolisthesis with spinal stenosis syndrome and right sciatica. The study offers valuable educational video footage detailing each step of the FE-TLIF procedure. The protocol incorporates the use of several instruments common to conventional TLIF procedures, an efficient outside-in technique with a trephine for IAP resection, endoscopic visualization for endplate preparation, and nerve protection. With proper education, FE-TLIF can be effectively learned, leading to favorable clinical outcomes while minimizing complications.
