Abstract: Hip fracture amongst the elderly is a growing concern especially with improvements in living standards and increasing lifespan. Currently, bone mineral density (BMD) is used by rule of thumb in the diagnosis of osteoporosis. It is well-established that the specificity and sensitivity of BMD is low in predicting fractures. Nevertheless, it is utilized as an approximate indication of bone quality due to ease of acquirement. Almost half of total hip fractures result from those without osteoporosis. Therefore, firstly, local osteoporosis, rather than generalized osteoporosis, was examined. By observing the local buckling ratio (BR) in the femoral neck in ten risedronate-treated subjects over three years, this work discovered that subjects with improved fracture loads, as predicted by finite-element analysis, were associated with lower local BR and vice versa. Secondly, the simultaneous dependence of critical fracture load on BR and BMD using triad graphic representations was proven superior over dyadic relationships.
