Representative final results of FEM analysis. Stress dispersion to the medial and lateral cortices (curved arrows) was significantly dominant (81.2%) in non-collapsed group (a). Intermediate results (b) were regarded as stress dispersion in the analysis. On the contrary, stress concentration to the lateral pillar (straight arrow) which proceeds to the primary compression trabeculae was markedly observed (87.5%) in the collapsed group (c)
