Development of a Finite Element Model to Predict Gap Displacement at Fracture Bridged Using Distal Femur Periarticular Locking Plate

Mechanical motion at a fracture site is known to affect the course of fracture healing. Perren’s interfragmentary strain theory assumes that the strain magnitudes in the fracture gap determine the subsequent differentiation of fracture gap tissue [1]. Gap strain is defined as the relative displacement of the fracture gap ends divided by the initial fracture gap width.
