Abstract

Problem statement: The interfragmentary strain (εIF) is the important parameter for femur fracture healing. The Dynamic Compression Plate (DCP) is commonly used in femur fracture. The DCP and the fractured femur are fixed by using the conventional screws. Approach: This research is proposed to investigate the effect of configuration of the screw fixation on the interfragmentary stain by using Finite Element Analysis (FEA), eight configurations of the screw fixation with the body load of 400 and 500 N. Results: The experimental results show that the relation of εIF and screws are the polynomial equations. Conclusion: We can decrease the interfragmentary strain by adding the number of screw with the groups of screw configuration.
