My Research Group

In collaboration with surgeons, orthopaedic biomechanical research is conducted with special interest in the upper limb. Evaluation includes fixation of implants to bone, kinematic analyses of motion, fracture fixation stability, and load transfer mechanisms across the joints. Experimental techniques include an electromagnetic tracking system to measure motion and custom-made simulators to model limb function in the laboratory. In addition, a bi-axial servo-hydraulic testing machine is used to test structures. The research laboratory which is located at the Lawson Health Research Institute, is dedicated to a “benchtop-to-bedside” approach, where discoveries in the laboratory are targeted to directly enhance patient care.
