Modeling the Mechanical Consequences of Age-Related Trabecular Bone Loss by XFEM Simulation
Figure 2
The process of age-related bone loss includes two steps: thinning of the trabecula and its eventual loss. The two-step degeneration process for single rod-like and plate-like trabecular bone cells was shown, respectively. (a) Degeneration process of the rod-like cell: trabecular rods at the two degenerated regions initially became thinner, after which part of these thinner rods were broken. (b) Degeneration process of the plate-like cell: trabecular plates at the two degenerated regions became thinner gradually; then part of these thinner trabecular plates were perforated.
