In light of the urgent need to enhance the current osteoporotic hip fracture risk assessment, CT- and DXA-based Finite Element simulations reproducing a sideways fall have been performed and their outcomes compared for a cohort of 28 patients.

Abstract
In light of the urgent need to enhance the current osteoporotic hip fracture risk assessment, CT- and DXA-based Finite Element simulations reproducing a sideways fall have been performed and their outcomes compared for a cohort of 28 patients. In spite of their projective nature, DXA-based models would be indeed already clinically attainable. The 2D and 3D outcomes were only moderately correlated, suggesting CT- and DXA-based models do not appear equivalent. In this light, DXA, which produces a 2D projective image, suffers from the positioning error, so that DXA images might show a proximal femur shape altered compared to the real 3D one. Interestingly however, the same patients were highlighted as at higher risk by the 2D and 3D predictors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
