Fracture risk and height: An association partly accounted for by cortical porosity of relatively thinner cortices

Journal of Bone and Mineral Research, 03/21/2013

Taller women are at increased risk for fracture despite having wider bones that better tolerate bending. As wider bones require less material to achieve a given bending strength, the authors hypothesized that taller women assemble bones with relatively thinner and more porous cortices because excavation of a larger medullary canal may be accompanied by excavation of more intracortical canals. Taller women assemble wider bones with relatively thinner and more porous cortices predisposing to fracture.
