  4. Abstract:
  5. Distal humerus fractures are complex injuries with potential implications on patient outcomes, necessitating thorough investigation and understanding of fracture characteristics and treatment options. This study employed a finite element analysis to explore the biomechanical behavior of double-plate osteosynthesis fixation for distal humerus fractures. The effects of screw diameter and angles on fixation stability and interfragmentary relative motion were evaluated using a full factorial design approach. The results revealed that screw diameter significantly influenced stiffness and normalized compression area, while interactions between entrance angles impacted axial motion control. However, no significant effects were observed for normalized shear area. These findings offer valuable insights into optimizing fixation approaches and promoting callus formation during fracture healing. Further research with patient-specific considerations is essential to enhance the generalizability and clinical applicability of the findings. © 2023 IEEE
