Studies by Finite Element Method of some Devices for Treatment of Intertrochanteric Fractures

摘要

The paper presents some studies of fixation devices for intertrochanteric fractures. The 3D bone model was obtained by digitizing an anatomical model of a femur. All the corrections needed were done in ProEngineer (ProE). The devices studied are: the fixed plate, the sliding screw-plate device, the intramedullary hip nail and Ender wires, designed in ProE. The final models were analyzed in Ansys. The stress and strain state is revealed; Also, some interesting aspects of the bone's fragment contact region are presesnted.
