Fig. 3From: Biomechanical analysis of reduction technique for lumbar spondylolisthesis: anterior lever versus posterior lever reduction methodSmall-sized compression load cells were inserted at the adjacent intervertebral disc. No.1-No.4 load cells were placed at L3/4 intervertebral disc. No.5–8 load cells were placed at L5/S1 intervertebral disc. The model was then set up on the mechanical testing system machineBack to article page
