Computer-navigated transfacet uniportal endoscopic lumbar interbody fusion: a novel technique and illustrative case series

Minimally invasive lumbar interbody fusion continues to evolve with advancements in navigation and endoscopic technologies aimed at reducing tissue trauma and improving safety. Conventional endoscopic fusion approaches, such as the interlaminar and trans-Kambin techniques, have inherent limitations regarding neural safety and implant positioning. We describe a novel computer-navigated transfacet uniportal endoscopic lumbar interbody fusion technique that leverages advanced navigation and endoscopic visualization to safely access the disc space via a transfacet corridor. We present an initial case series to demonstrate the clinical feasibility, safety, and effectiveness of this technique.
