Abstract

Problem statement: Young’s modulus and interfragmentary strain (εIF) are the important parameters in bone-plate testing and design. But Young’s modulus is not suitable when we use with εIF in the bone-plate testing. Approach: This research proposed a study on the Interfragmentary Modulus (IM) as the new parameter for the bone-plate testing. Results: The results from the FEM show that the relations of the interfragmentary stress (σIF) and interfragmentary strain are linear for all cases with the condition of the DCP and the screws material properties are linear and isotropic materials. Conclusion: IM are the constant values and we can use IM in the bone-plate testing.
