After successful completion of the course, students are able to...

• ... explain the hierarchical structure of bone.
• ... explain the constitutive behaviour of bone and implant constructs.
• ... explain the difference between structural and material properties.
• ... explain how orthopaedic mechanical tests of bone and implants are designed and conducted.
• ... explain how experimental testing data is evaluated, and material parameters are extracted.

In addition, the students have conducted a mechanical test on a bone specimen on their own in the biomechanics laboratory at the Karl Landsteiner University of Health Sciences in Krems and have evaluated the obtained data.

Part I: Theory

• A brief overview of the structure and mechanical properties of bone.
• Introduction to the mechanical behaviour of orthopaedic implants.
• A practical step-by-step description on designing and conducting an orthopaedic mechanical test. In particular: design of boundary conditions, measurement of force, displacement, strain, biological sample preparation, choosing a loading protocol, data evaluation,  extracting material/structural properties, “accuracy” vs. “precision”
• An overview of recent biomechanical studies conducted in the field at TU/KL* and their relevance in clinical practice and/or basic science.

Part II: Seminar

As preparation for the upcoming workshop, the students draft an experimental design for the workshop experiment at home and present it in a short presentation.

Part III: Laboratory Workshop

In a one-day excursion to the Biomechanics Laboratory of the KL*, each student will prepare a small bone sample and test it in a mechanical testing machine till failure. The generated data is handed over to the student for evaluation. The travel expenses to/from Krems have to be paid by the student him/herself. COVID19: The 3G-rule applies and a FFP2 mask has to be worn.

The students evaluate the data recorded in the workshop and write a technical report on the experiment. The report is handed in and discussed in an exercise interview with the lecturer. The grade is based on the report and the exercise interview.
