A surgical planning system for use in surgical procedures to repair an anatomy of interest includes a preplanning system to generate a virtual surgical plan and a mixed reality system that includes a visualization device wearable by a user to view the virtual surgical plan projected in a real environment. The virtual surgical plan includes a 3D virtual model of the anatomy of interest. When wearing the visualization device, the user can align the 3D virtual model with the real anatomy of interest, thereby achieving a registration between details of the virtual surgical plan and the real anatomy of interest. The registration enables a surgeon to implement the virtual surgical plan on the real anatomy of interest without the use of tracking markers.

A computerized method for estimating bone mineral density, z and t-scores and/or fracture risk by receiving single-energy x-rays of the thoracic spine, chest x-ray, lumbar spine, whole body x-ray, hip, arm, leg, hand or foot in addition to imaging technical parameters and clinical parameters such as patient demographics, medical history, and other risk factors. The results are presented to a user for the diagnosis or screening of osteoporosis and/or risk stratification of osteoporotic fractures. A classifier may be trained using a dataset of single energy x-rays correlated to results from dual energy x-ray readings performed in the same patient and of the same body part, along with fracture incidence, to correlate the inputs provided to the desired output. A classifier may also be trained to predict fracture risk directly from x-ray image data and optionally additional patient characteristics.
