Dual-energy X-ray absorptiometry (DXA), the current standard for diagnosing osteoporosis, does not account for the three-dimensional distribution of bone. Cross sectional stiffness, EI, derived from a testing method called mechanical response tissue analysis (MRTA) offers an alternative to account for the whole bone structure. This thesis computes EI of the ulna through FE modeling. Eighteen cadaveric ulnae were CT scanned, modeled, and simulated in static, modal, harmonic, and fracture analyses. Collaborators tested the same ulnae by static mechanical tests and MRTA. Significant correlations in EI were shown for both the static and harmonic test (R2 = 0.979, R2 =0.978) with corresponding experiments, with slopes near unity. High correlations were found in the maximum load and work to fracture (R2 = 0.871, R2 = 0.813). These results advance the goal of simulating ulna mechanics in support of MRTA development.
