Bone compressive strength
Webof compressive strength of cancellous bone in the trans-verse direction exceed the corresponding values in the axial load direction. This is probably because at these low apparent densities measurements might be more inaccurate and orientation among the trabeculae less measurable. Data concerning the tensile and torsional strength of … WebAbstract Trabecular bone is a complex material with substantial heterogeneity. Its elastic and strength properties vary widely across anatomic sites, and with aging and disease. Although these properties depend very much on density, the role of architecture and tissue material properties remain uncertain. It is interesting that the strains at which the bone …

Webdecrease in bone mass resulting from a predominance of osteoclast activity. -When the normal stresses exerted on the bone by muscle contractions, weight bearing or impact forces are reduced. Bone demineralization is a potentially serious problem - as bone mass diminishes, strength and thus resistance to fracture also decreases.
