The degree to which periosteal apposition rate varies relative to robustness, anatomical site, and age was quantified from Figure 2 for the General Condition (Ct.ArS = Ct.ArR), the 66% site (Ct.ArS < Ct.ArR), and the 38% site (Ct.ArS ≪ Ct.ArR). A) Periosteal apposition rate quantified at an arbitrary early age (50 years) is greater for robust bones when there is less disparity in cortical area among individuals (Ct.ArS = Ct.ArR, Ct.ArS < Ct.ArR). This relationship reverses at the 38% anatomical site when the cortical area of slender bones is much less than the cortical area of robust bones (Ct.ArS ≪ Ct.ArR). B) Slender diaphyses required greater percent increases in periosteal apposition rate from 45 to 90 years of age compared to robust diaphyses.
