Abstract

We have reviewed highlights of the research in trabecular bone biomechanics performed over the past 20 years. Results from numerous studieshave shown that trabecular bone is an extremely heterogeneous material-modulus can vary 100-fold even within the same metaphysis-with varying degrees of anisotropy. Strictly speaking, descriptions of the mechanical properties of trabecular bone should therefore be accompanied byspecification of factors such as anatomic site, loading direction, and age. Research efforts have also been focused on the measurement of mechanical properties for individual trabeculae, improvement of methodsfor mechanical testing at the continuum level, quantification of the three-dimensional architecture of trabecular bone, and formulation of equations to relate the microstructural and continuum-level mechanicalproperties. As analysis techniques become more sophisticated, there is now evidence that factors such as anisotropy and heterogeneity of individual trabeculae might also have a significant effect on the continuum-level properties, suggesting new directions for future research. Other areas requiring further research are the time-dependent and multiaxial failure properties at the continuum level, and the stiffness andfailure properties at the lamellar level. Continued research in theseareas should enhance our understanding of issues such as age-related bone fracture, prosthesis loosening, and bone remodeling.
