This calculator estimates the probability of hip fracture within 10 years for post-menopausal women. The risk prediction is based on clinical data collected by the Women's Health Initiave (WHI). The calculator includes common factors such as age, height, and weight but also includes DXA-related factors such as bone mineral density (BMD) and hip geometry derived from hip structural analysis (HSA). 
Beside the ability to incorporate hip geometry factors in the prediction, this calculator also represents a new generation of risk models which combine clinical data as well as computational data from finite element analysis. The new data fusion algorithm behind this calculator is the product of a collaboration between the Aerospace and Mechanical Engineering (AME) department and the Epidemiology and Biostatistics department at the University of Arizona. For details on the techniques used, see our article in the Journal of Biomechanics.
This calculator is designed to be usable for novices, health professionals, and researchers alike. In fact, the development of such a calculator is always a work in progress and we are always looking for feedback or collaborations.

Important: If you chose the "stochastic strain" option, the computation will last about two minutes.  In any other case, it should be almost instantaneous. If the calculation seems to be stuck (i.e., displaying "working" for a long time), make sure to clear the cache from your browser.
