Fig. 2From: Biomechanical feasibility of semi-rigid stabilization and semi-rigid lumbar interbody fusion: a finite element studyDifferent L4/5 surgical constructs. Surgical constructs simulated in this study including PD + SIS, PD + PSI, Cage, Cage+SIS, Cage+SPI, and Cage+PI. Interbody fusion with cage implantation was indicated in green. Semi-rigid and rigid instrumentation were indicated in blue and purple, respectivelyBack to article page
