Comparative Study of Fixation Devices for Intertrochanteric Fractures

摘要

The paper presents a comparison of some fixation devices for intertrochanteric fractures. The devices studied are: the fixed plate, the sliding screw-plate device, the intramedullary hip nail and Ender wire. The devices are designed in ProEngineer (ProE). The 3D models were analyzed in Ansys. Different materials are investigated and aspects concerning the stress and strain state, the loading of the contact area between bone fragment and bone - device.
