A Biomechanical Comparison of Two Intramedullary Implants for Subtrochanteric Fracture in Two Healing Stages: A Finite Element Analysis

Figure 4

Tensor plot of the principal stresses of the two models’ callus in the two different healing stages (a, b) with direction; the red colour represents compressive stress and the blue colour represents tensile stress; (c, d) with value. (a) PFNA-II model in SCS; (b) A2FN model in SCS; (c) PFNA-II model in HCS; (d) A2FN model in HCS.
