Simulation study demonstrates the influence of muscle forces on femoral load distribution, highlighting the need for realistic experimental setups in fracture testing.
Introduction: Biomechanical experiments of the hip joint often only consider the loading of the femoral head, neglecting the effects generated by the muscle forces, due to the complex nature of the loading case at the femur. This study aims to examine the significance of neglecting the influence of the muscles to the loading of the bone, while proposing a more realistic setup for experimental testing of pertrochanteric femoral fractures. From the finite element simulations, a factorial analysis is done to assess the significance of the contribution of each individual muscle to the overall sectional forces and moments at the critical region of the femur.
