QUASR launches
The Queensland Unit for Advanced Shoulder Research (QUASR) launched at Queensland University of Technology in late January 2020. It was conceived by Assoc Prof Ashish Gupta, shoulder surgeon.
The launch coincided with a successful ITTC grant, reported at approximately $8 million over four years, awarded jointly with QUT and other universities.
What the unit was set up to do
A research unit of this kind exists to put surgeons and engineers in the same programme of work. The clinical questions arise in the operating theatre and the clinic: why a repair fails in one pattern of tear and holds in another, how the position of an implant changes the movement available afterwards, how much bone can be lost from the socket before a soft tissue repair will no longer hold. Answering them requires measurement equipment, modelling expertise and research students, which is what a university unit provides. Individual results vary.
What an ITTC grant funds
Industrial Transformation Training Centre grants are awarded by the Australian Research Council to fund research training conducted in partnership with industry. The money supports research students and postdoctoral researchers working on projects defined jointly with the industry partners, over a fixed term rather than indefinitely. The emphasis on training is deliberate: the intended output is not only published findings but a cohort of researchers who have worked on real industrial and clinical problems and can continue to do so afterwards.
Why shoulder research needs engineers
The shoulder is the most mobile joint in the body, and it achieves that range by having a shallow socket and relying on soft tissue rather than bony constraint for its stability. That trade-off is why instability and tendon failure are common shoulder problems, and it makes most of the open questions mechanical ones: how load is distributed, how fixation holds, how far a joint can move before the components collide, how wear accumulates over years. Those questions are addressed with testing rigs, motion capture, imaging and computational models, which are engineering tools rather than clinical ones.
