Current research interests
Studying the interface mechanics established between metallic implants and bone issue is a core focus on the ORTHOtron lab. We are primarily interested in identifying mechanical factors related to implant fixation and loosening under physiologic loading in the spine.
Current project(s): Characterization of multi-axial fatigue of spinal implant loosening
We use finite element software to develop robust models to investigate the biomechanics of impact and injury to identify factors associated with injury risk and prevention.
- Finite element modeling of spinal cord impact and injury risk
- Finite element modeling of muscle activation in the cervical spine
Joint motion simulation
In vitro experimental investigations of human joint motion using state-of-the-art equipment is used to quantify tissue and joint mechanics to better understand normal, pathologic and repaired states.
- Simulation and measurement of physiologic spinal loading associated with daily activities of living
Computer-assisted orthopaedic surgery
Our group develops software and hardware tools for computer-assisted surgery, ranging from surgical simulation to 3D image-guided navigation.
- Virtual simulation of pedicle screw insertion
- Visualization of spinal cord tractography
Additive manufacturing of surgical implants and instruments
Working with leaders in Multi-scale Additive Manufacturing at Waterloo, we are investigating next generation surgical implant and instrument designs.
- Optimization of interbody cage design and manufacturing
