Figure 6From: Biomechanical comparison of unilateral and bilateral pedicle screws fixation for transforaminal lumbar interbody fusion after decompressive surgery -- a finite element analysis For the unilateral fixation, the stresses distribution in annulus at surgical level of TLIFo model under (A) right axial rotation (RAR) or (B) right lateral bending (RLB), and the cage-bone interface under (C) RAR or (D) RLB. The stresses distribution in annulus at surgical level of TLIFo model supplemented with a translaminar facet screw contralaterally under (E) RAR or (F) RLB, and the cage-bone interface under (G) RAR or (H) RLB.Back to article page
