Descrição: Current theoretical and experimental evidence suggests that the sensory bone cells are activated by the induced drag from fluid flowing through the lacunar-canalicular porosity (PLC). One of the most important parameters of the interstitial fluid flow is the PLC permeability. However, the reported measurements of this permeability span over eight orders of magnitude in literature. In this work, innovative analytical and experimental approaches were proposed to accurately estimate the PLC permeability that was determined in a single human osteon, a domain in which the PLC can be separated from the vasular porosity (PV). Based on the curve fitting of the experimental measurements of loss tangent on cyclically loaded osteons at different frequencies to the analytical model, the PLC permeability was preliminary determined to be on the order of 10-22 m2.
