Comparison of the Lag Screw Placements for the Treatment of Stable and Unstable Intertrochanteric Femoral Fractures regarding Trabecular Bone Failure

Figure 5

The anterior-posterior sectional views of the compressive strain distributions of the femur trabecular heads (31-A1.1 fracture type) in nine DHS positions and graphical percentages of the strain values according to the gauge bar. The regions having strain values at below 1% are under a higher risk of trabecular bone failure.
