Cortical and trabecular mechanical properties in the femoral neck
... vary differently with changes in bone mineral density
Recent publication
The Division of Biomechanics at KL has teamed up with TU Wien to analyse the quality criteria of the femoral neck bone. The researchers took samples from healthy individuals and patients with osteoporosis. They assumed that it was not only bone density but also other bone properties that determined the fracture strength of the bone. Interestingly, there were hardly any differences between healthy and osteoporotic bone samples in the analysed characteristics. However, the researchers found that different parts of the bone, namely cortical and trabecular bone, behaved differently. While the cortical bone is dense, the trabecular bone can be described as spiongy and therefore softer. Osteoporosis could therefore also be the result of a shift from cortical to more trabecular bone components. The work is freely available in the scientific journal "JBMR Plus" and was funded by the government of Lower Austria as part of its RTI strategy.
