Indentation distance increase (IDI), a measurement of bone quality, correlated with the maximum screw torque achieved at the femoral middiaphysis in both the (A) 4.5mm OD screw (p<0.01; Pearson’s correlation; R=−0.57; MSE=0.82 N/mm) and (B) the 3.5 mm OD screws (p<0.01; Pearson’s correlation; R=−0.61; MSE=0.10 N/mm). Specifically, the more resistant the bone is to indentation, the more torque it can sustain.
