The bone strain index (BSI) is a marker of bone deformation based on a finite element analysis inferred from dual X-ray absorptiometry (DXA) scans, that has been proposed as a predictor of fractures in osteoporosis. BSI value represents the average equivalent strain in a skeletal site, assuming that a higher strain level (higher BSI) indicates a lower bone’s resistance to loads with consequent higher risk of fractures. BSI index is usually calculated for specific loading ...
