Figure 5From: Biomechanical evaluation of three surgical scenarios of posterior lumbar interbody fusion by finite element analysis Contour plots of Von Mises stresses on bone grafts for each surgical model in torsion. (a) the graft-1 in the PCT model, (b) the graft-2 in the PCT model, (c) the graft-3 in the PCT model, (d) the graft-1 in the PCP model, (e) the graft-2 in the PCP model, (f) the graft-3 in the PCP model, (g) the AIB in the PAIB model.Back to article page
