The Challenge

The Orthopedic Research Group at the University of Western Ontario in Canada conducts experimental testing of new surgical materials and methods. The group focuses on joint implants, fracture-fixation devices and sports medicine-related issued and, in particular, on gaining a clearer understanding of the internal stresses in the hip bone by using finite element analysis.

In order to develop the best new joint implants and fracture fixation devices, the Orthopaedic Group needed to used finite element analysis to gain a better understanding of the internal stresses in the human hip bone.

The Solution
The group decided to use COSMOSM for finite element analysis to gain a more accurate description of the stresses involved. The researchers modeled the hip bone using 3D isoparametric and prism-shaped solids, representing the model with a total of five material properties. They then pieced together individual sectors into a continuous model by merging them.

After comparing the analysis results directly with experimental data, the Group decided that analysis provides a valuable tool in the research and development of future medical implants.
