Experimental validation of DXA-based finite element models for prediction of femoral strength

- We measured the human femoral strength in one-legged stance and sideways loading configurations.
- We evaluate the ability of subject-specific DXA-based finite element models in predicting the femoral strength ex vivo.
- We compared predictions of femoral strength among densitometric measurements, DXA-based models and QCT-based models.
- Subject specific QCT-based 3D finite element models explained 80-85% of femoral strength.
- Subject specific DXA-based 2D finite element models explained 74-77% of femoral strength.
