摘要

Objective To set up a three-dimensional (3-D) finite element (FE) model of Less Inwasive Stabilization System (LISS) intreating distal femoral fractures(AO/33-A3),and make preliminary biomechanical analysis,which can provide a scientific basis for future clinical application.Methods To obtain information of the spatial structure of the femur by CT scan,then to build their three-dimensional solid model using of software,and use three-dimensional reverse engineering to obtain three-dimensional model of LISS.The model was assembled using the ABAQUS,then meshed and simulated axial compression force,the stress distribution of femur and LISS plate.Results The largest stress of the LISS focuses on the edge of the plate and the region which is close to the femur.
