| Abstract Scope |
The diagnosis of osteoporosis in patients prior to a fragility fracture remains a challenge. Here, bone material properties might improve diagnostic prediction. Here, the putative change of bone properties with age and disease is of interest. Conducting mechanical tests at the meso- and micro scale and comparing trabecular and proximal bone from osteoporotic and healthy donors, diseased bone was not different to healthy bone. Additionally, trabecular and cortical bone tissue are often thought to display similar linear elastic behavior and properties at the tissue level. However, our experiments on trabecular and cortical bone from the same human donors show, that these are in fact two distinct tissues. At low strains cortical bone displays linear elastic behavior while trabecular bone is viscoelastic. As the femoral neck cortex undergoes trabecularization with age, this may have a significant effect on bone fragility, yet clinical relevance of this remains to be shown. |
