Research

Studying the interface mechanics established between metallic implants and bone tissue is a core focus of 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.

Current project(s):

• Finite element modeling of spinal cord impact and injury risk
• Finite element modeling of muscle activation in the cervical spine

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.

Current project(s):

• Simulation and measurement of physiologic spinal loading associated with daily activities of living

Our group develops software and hardware tools for computer-assisted surgery, ranging from surgical simulation to 3D image-guided navigation.

Current project(s):

• Virtual simulation of pedicle screw insertion
• Visualization of spinal cord tractography

Working with leaders in Multi-scale Additive Manufacturing at the University of Waterloo, we are investigating next generation surgical implant and instrument designs.

Current project(s):

• Optimization of interbody cage design and manufacturing
