Structural Analysis and Optimization of the Support Device Used for a Proximal Fracture of the Femur

摘要

The support system for a proximal fracture of the femur is studied by means of the finite element method. The support system of the Gamma III by Stryker is used for this study due to the versatility and simplicity of the system. The variance of each system was modeled to validate the results. Parametric studies between the models were conducted and design improvements were then tested against the existing parameters. Given the material properties for the Ti-6 AL-4V support system and bone, the models were considered under two different load conditions. From these results, a recommendation can be made to the manufacturing and medical community as to the effective use of the Gamma III nail implant system for a proximal fracture in the femur.
