- Abstract: Objective To explore the biomechanical characteristics of femoral neck fracture with triangular stabilization and fixation system by finite element analysis. Methods The CT imaging data of the femur in a healthy young volunteer was obtained, and the three-dimensional models of the femur and femoral neck fracture were constructed. Ansys12.1 finite element analysis software was used to simulate the effects of regular triangular and inverted triangular stabilization and fixation systems on the stress distribution of internal fixator and the displacement of the fracture when human body was in upright posture. Results The maximum equivalent stress of femoral head in regular triangular and inverted triangular internal fixation models was similar, while the maximum equivalent stress of internal fixator in inverted triangular internal fixation model was lower than that in regular triangular internal fixation model. Moreover, the differences in the maximum displacements of proximal femur and internal fixator between regular triangular and inverted triangular internal fixation models were trivial. Conclusion There is no significant difference between regular triangular and inverted triangular stabilization and fixation systems in the maximum equivalent stress of femoral head, the maximum displacement of proximal femur and the maximum displacement of internal fixator, but the maximum equivalent stress of internal fixator in inverted triangular internal fixation model is lower.
