Abstract

For several years the distance between plate and femur has been studied for preventing the damage to the blood supply by the contact pressure between plate and femur. The Limited Contact Dynamics Compression Plate (LC-DCP) is normally used to create the distance by using the locking screws. However, increasing of the distance between plate and femur affects the interfragmentary stain and the interfragmentary modulus. The interfragmentary strain is the main factor of femur-fractured healing. While the interfragmentary modulus is the new interesting factor of the stability of the femur and plate. This research proposes a study of the effect of the distance between plate and femur on the interfragmentary stain and the interfragmentary modulus. The interfragmentary strain is increased when the distance increases while the interfragmentary modulus is decreased by increasing the distance.
