Biomechanical Effects of Cage Position in Full-endoscopic Trans-Kambin's Triangle Lumbar Interbody Fusion: A Finite Element Analysis.

ABSTRACT: Full-endoscopic trans-Kambin's triangle lumbar interbody fusion is considered a minimally invasive procedure. The cage position in Kambin's triangle lumbar interbody fusion differs from that in other types of lumbar interbody fusion; the cage is inserted via the foramen and placed diagonally to the endplate. Therefore, the ideal cage position remains uncertain. This study evaluated the biomechanical effects of different cage positions in Kambin's triangle lumbar interbody fusion at L4/5. An intact lumbar-to-femur finite element model was constructed. A diagonal line was first set with the foramen as the starting point, and this was used as the reference line [K(0°)] for the cage insertion angle. Five insertion angles were set: 10° and 20° anteriorly [K(10°) and K(20°)], 0° [K(0°)], and 10°
