The objective of this project is to create a new intertrochanteric hip fracture implant that decreases the amount of lateral extrusion while maintaining compression along the fracture line and limiting any angular torsion.

Project Summary
Overview
Hip fracture fixations are one of the most common procedures involving implants in the United States. The current sliding designs result in a lateral extrusion that causes discomfort for the patient, leading to revision surgeries. The creation of a femur implant that introduces more flexibility could benefit patients’ healing because of increased micromotion and limited extrusion.
Objectives
– Intertrochanteric hip fracture implant that decreases the amount of lateral extrusion
– Maintain compression along the fracture line
– Limit any angular torsion
Approach
– Conduct weekly meetings with sponsors to understand the surgeon’s needs and receive progress feedback.
– Collect existing hip implants and femur models from our sponsor.
– Research contemporary implant products in the market and review related patents.
– Generate multiple concepts to help select the best-fit design.
– Design the initial project design through sketches.
– Create a 3D model of our hip implant using CAD (SOLIDWORKS).
– Analyze the implant’s performance under different forces through Finite Element Analysis (COMSOL).
– Fabricate prototypes of our design using 3D printing.
– Purchase materials to represent NITINOL behavior in our prototype.
– Validate our model and simulation results by reviewing it with our sponsors.
Outcomes
– The sponsor will save up to millions of dollars by reducing revision surgeries due to this project.
– This project is the first design for Penn State College of Medicine to solve the problem of protrusions resulting from current intertrochanteric hip fracture solutions.
