Figure 4From: Biomechanical evaluation of three surgical scenarios of posterior lumbar interbody fusion by finite element analysis The results of IDP of models A to E. (a) the results of IDP in extension, (b) the results of IDP in flexion. (Models A to E were five remeshed L4-L5 models with different mesh densities. The detailed parameters of the mesh densities of these models were shown in Table 6.)Back to article page
