Ferguson Group / Laboratory for Orthopaedic TechnologyOpen OpportunitiesIn this project we would like to further explore if we can use our established Melt electrowritten tubular scaffolds and combine them with gels toward the application for vascular grafts. Melt electrowritten scaffolds allow us to finely control the wall geometry, which leads to controlled mechanical properties as well as porosity. However there are some limitations with this technology. This is where the addition of gels in the scaffold wall could benefit with porosity control, leackage as well as possible cell growth benefits.
Therefore we would like to investigate which gel would be viable for the application of a vascular graft based on mechanical and biological needs. We would find possible solutions to combine MEW scaffolds with gels and practically try different methods. Once a protocol(s) are established we would perform quantitative and mechanical characterisation and compare it to MEW only scaffolds as well as native tissues. - Biomedical Engineering, Chemical Engineering, Materials Engineering, Mechanical and Industrial Engineering

| Lumbar spinal stenosis (LSS) is a condition characterized by the narrowing of the lumbar spinal canal, resulting in compression of the nerve roots or cauda equina. Patients with LSS often exhibit altered spinal kinematics and compensatory movement patterns, which can increase paraspinal muscle activity and segmental loads. This study aims to estimate the spinal loads in LSS patients using an advanced full-body musculoskeletal model within the AnyBody Modeling System, incorporating patient-specific motion-capture data. Gaining a deeper understanding of the differences in spinal kinematics between LSS patients and healthy individuals, and their effects on spinal loading, could inform more effective treatment and rehabilitation strategies. - Biomechanical Engineering

| While we have performed some basic mechanical tests to characterize Melt electrowritten tubular scaffolds, we would like to add other mechanical tests, based on ASTM standards, that would further allow us to have a better insight into mechanical properties of MEW scaffolds as well as to compare them to other vascular grafts as well as native tissues. Therefore we are searching for a motivated student who can see themself performing practical work producing tubular scaffolds as well as implementing mechanical tests. - Biomedical Engineering, Materials Engineering, Mechanical and Industrial Engineering

| Lumbar intervertebral disc degeneration (LDD) is estimated to affect 400M individuals worldwide annually, which causes pain and disability for the patients affected by it [1]. Continuous localized, and structural degeneration on multiple intervertebral disc (IVD) levels can progress to accumulated macroscopic deformities, manifesting in abnormal spinal curvatures, also known as Adult Spinal Deformities (ASD). LDD and spinal alignment are hypothesized to be closely interrelated, with specific alignment parameters showing mutual correlations with the degree of LDD [2].
Through analyzing longitudinal data - including X-ray-derived biplanar alignment parameters and MRI-based Pfirrmann grading - this study aims to identify extensive patterns between alignment characteristics and the individual degenerative state of lumbar IVDs. Such insights could improve our understanding of degenerative cascades and influence decision making in clinical treatment approaches by identifying alignment profiles at higher risk for degeneration. The proposed study includes a clinical cohort of degenerative lumbar back pain patients who were treated conservatively, and followed up over a period of 3-5 years, before eventually undergoing surgery at Schulthess Clinic Zurich.
This project is jointly supervised by an interdisciplinary group of researchers and clinicians of ETH Zurich and Schulthess clinic Zurich, which offers insights into fundamental spinal research, as well as daily clinical practice. Your tasks will include data annotation, model development, and collaborative discussions of results, providing a comprehensive experience in interdisciplinary research. This project offers an excellent opportunity to engage in impactful research at the intersection of biomechanics, clinical practice, and data-driven modeling.

| Background:
Lower back pain is one of the most prevalent health issues in Switzerland, with severe socio-economic consequences and a leading cause of reduced work performance. Approximately 20% of spinal fusion surgeries performed using off-the-shelf implants result in the surgical outcome being compromised post-operatively, often requiring one or more revision surgeries to address the associated pain.
The Laboratory of Orthopedic Technology has recently developed a novel spinal implant using topology optimization, which is currently undergoing a feasibility study for clinical applications.
We are seeking a master’s student who is passionate about medical devices and mechanical design and testing to join us for a semester project or master thesis. In this role, you will gain insight into the spinal surgery process, receive input from surgeons, and contribute to the mechanical design and testing of the implant.
Objectives:
• Perform the CT scan on animal vertebrae
• Evaluate the influence of implant placement/location variability
• Mechanical testing on the implant
• Develop surgical tools if needed
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:
Spring semester in 2025

| Understanding the differences in spine kinematics between patients with lumbar spinal stenosis and those with healthy spines, along with the implications for spinal loading, could shed light on the pathophysiology of this disease and contribute to the development of more effective treatment and rehabilitation strategies. To estimate spinal loads, a novel full-body musculoskeletal model developed in AnyBody Modeling System will be used. This model will be customized to reflect subject-specific spinal alignment and will be driven by kinematic data obtained from in vivo motion-capture measurements. Inverse dynamics simulations of patient-specific spinal postures and forward flexion trials will be performed to estimate the corresponding loads. - Biomechanics
