Computational design optimization of a motion preserving spinal implant
Following trauma or due to degeneration it can be necessary to replace one or more intervertebral discs with an implant, a so-called Total Disc Replacement (TDR). Such devices enable motion though surfaces articulating against each other. While this treatment is clinically successful, it is connected to considerable complication and reoperation rates. Therefore, we are optimizing the design of such an implant to address these issues. While many different designs and design types have been proposed and are used in clinical practice, there is no consensus on what design or design type is the most beneficial. However, it is hypothesized, that replicating the situation that is present in healthy (asymptomatic) subjects as closely as possible, is optimal. Since the motions of the cervical spine are coupled (coupling of rotation and translation as well as multiple rotations) the optimal design of the articulating surfaces is not obvious. Therefore, this master’s thesis project aims at designing the implants articulating surfaces using parametric design optimization in LS-OPT based on finite element simulations.

Semester Project_Design customized molds for manufacturing a novel joint implant
Background: The Laboratory of Orthopedic Technology has recently developed a novel joint implant and is undergoing optimization of the manufacturing process. We are looking for a master's student who is passionate about medical devices and mechanical design to join us for a semester project. Objectives: • Design different molds for material casting using SolidWorks or Fusion 360. • Optimize implant using matlab or Python. • Utilize 3D printing or laser cutting to create the molds. • Conduct mechanical tests on the implants. Your Profile: • Strong knowledge in mechanical design and drawing skills. • Hands-on and detail-oriented. • Experience with SolidWorks or Fusion 360, as well as Python or Matlab. Timeframe: Starting ASAP until the end of September.
