High porosity bone
WebOver 75% of the skeleton is assembled as cortical bone. Of all fragility fractures, ~ 80% are appendicular and involve regions rich in cortical bone and ~ 70% of all age-related appendicular bone loss is cortical and is mainly due to unbalanced intracortical remodeling which increases cortical porosity.

WebOct 13, 2024 · The parameter can also be expressed in terms of porosity (P) by considering the relationship: P = (V 0 −V)/V 0, which is generally expressed in terms of percentage. The analysis performed was aimed to structurally evaluate high porosity structures. Therefore, a volume fraction of 0.10 equivalent to a porosity of 90% was considered.
WebHigh porosity makes trabecular bone compliant and large variations in architecture leads to high heterogeneity. The modulus and strength vary inversely with porosity and are highly dependent on the porosity structure. The effects of aging and small cracking of trabecular bone on its mechanical properties are a source of further study. WebAug 1, 2024 · The optimal pore microarchitecture (i.e. pore size and porosity) for scaffolds to be used in bone grafting for cortical bone was set to <212μm with volumetric porosity values of 27-37%, and for trabecular tissues to 300-500μm with volumetric porosity values of 54-58%. The pore size range 212-300μm with volumetric porosity values of 38-56% ...
WebCortical bone is of variable thickness and porosity (the number and size of pores). Both trabecular and cortical bone may also show microcracks as a result of mechanical loading. ...
