Mechanical Evaluation of Two Hybrid Locking Plate Designs for Canine Pancarpal Arthrodesis

Figure 3

Illustration of the two-step FEA with virtual prebending of the oval hole (OH) plate and simulation of in vivo loading conditions by axial compression; OH plate fixed between two rollers before (a) and after (b) the bending process. Residual stresses derived from the prebending phase were transferred for the second step of the FEA. (c) Boundary conditions for simulation of in vivo loading conditions were based on the experimental set-up. Magnification shows radiocarpal hole and bending point with applied refined mesh (0.8 mm) in this region.
