文摘
- •
Proximal femur fracture was induced in drop tower tests mimicking fall (N=14).
- •
Homogenized finite element (hFE) models were generated automatically from CT images.
- •
Quasi-static hFE analysis predicted hip fractures occurring in dynamic sideways fall.
- •
Strength (R2=0.84), stiffness (R2=0.82) and fracture energy (R2=0.72) were predicted.
