- Figure 1
Micro FE model of bilateral kyphoplasty with beam and solid elements. FE, finite element.
- Figure 2
BEAM188 element coordinate system and equivalent strain computation.
- Figure 3
Generation of beam element models after skeletonization of computed tomography data and applied boundary conditions for Mode I tensile and Mode II shear separation. Failure curves output from the micro FE analysis were applied in the macroscale model by explicitly defining the normal and tangential contact stiffness between the bone and cement domains. FE, finite element.

(a) Finite element model of thoracolumbar junction T12-L1-L2 in healthy intact state. (b) Model with simulated wedge fracture at L1. (c) Wedged model with bilateral kyphoplasty at L1 with cortical and trabecular components hidden for clarity.
- Figure 5
Mean bone-cement interface separation response for the cement masses with full interlock and reduced interlock applied.
- Figure 6
Mode I tensile separation stress normalized to failure strength with full interlock.

Mode II shear separation stress normalized to failure strength with full interlock.
- Figure 8
Mode I tensile separation stress normalized to failure strength with reduced interlock.
- Figure 9
Mode II shear separation stress normalized to failure strength with reduced interlock.
