Capstone Design

Abstract Insufficient engineering analysis is a common weakness of student capstone design projects. Efforts made earlier in a curriculum to introduce analysis techniques should improve student confidence in applying these important skills toward design. To address student shortcomings in design, we implemented a new design project assignment for second-year undergraduate biomedical engineering students. The project involves the iterative design of a fracture fixation plate and is part of a broader effort to integrate relevant hands-on projects throughout our curriculum. Students are tasked with (1) using computer-aided design (CAD) software to make design changes to a fixation plate, (2) creating and executing finite element models to assess performance after each change, (3) iterating through three design changes, and (4) performing mechanical testing of the final device to verify model results. Quantitative and qualitative methods were used to assess student knowledge, confidence, and achievement in design. Students exhibited design knowledge gains and cognizance of prior coursework knowledge integration into their designs. Further, students self-reported confidence gains in approaching design, working with hardware and software, and communicating results. Finally, student self-assessments exceeded instructor assessment of student design reports, indicating that students have significant room for growth as they progress through the curriculum. Beyond the gains observed in design knowledge, confidence, and achievement, the fracture fixation project described here builds student experience with CAD, finite element analysis, 3D printing, mechanical testing, and design communication. These skills contribute to the growing toolbox that students ultimately bring to capstone design.

Biomechanical Behavior

Femur fractures are caused by high energy trauma or by musculoskeletal impairments, such as osteoporosis. The presence of total hip replacement (THR) superior to a femoral mid-shaft fracture greatly complicates fixation and treatment. The most conventional fracture fixation method is internal fixation by metal plate and screws. However, metal being stiffer than bone, causes stress shielding and bone resorption. The goal of this study was to evaluate the performance of a less stiff carbon fibre epoxy plate as fracture fixation in an injured and healed femur. IR thermography validated by finite element analysis (FEA) was used to investigate the stress patterns of an injured and healed femur under an average cyclic loading of 800 N at an adduction angle of 7 degrees to simulate the single-legged stance phase of walking. The average stiffness of an injured femur with carbon/epoxy plate was 532.1 N/mm (static) and 625.3 N/mm (dynamic) respectively, that increased to 597.6 N/mm (static) and 697.9 N/mm (dynamic) for the metal plate. For the healed femur, the average stiffness increased from 1660.3 N/mm (static) and 2010.0 N/mm (dynamic) for the carbon/epoxy plate to 1704.4 N/mm (static) and 2070.4 N/mm (dynamic) for the metal plate. IR stress maps for carbon/epoxy and metal plate (injured femur) showed an overall difference of 29.2% for the anterior and posterior sides. This is the first study to assess experimentally and computationally the biomechanical behavior of injured and healed synthetic femur with two different plates construct.
