The document discusses the application of computer aided engineering (CAE) techniques like finite element analysis to predict stress transfer in femurs after implantation of standard and short femoral stem hip implants. Specifically, it details: 1) Creating 3D CAD models of femurs from CT scan data and designing stem implants. 2) Reviewing forces on femurs during gait and applying them in finite element analysis models. 3) Analyzing the models to compare stress distributions between standard and short stem implants, finding the short stem allows a more physiological stress distribution. 4) Concluding CAE techniques like CAD and FEA can effectively examine implant designs before surgery and optimize factors affecting bone stress.
