About Our Team

The Shoulder Centre was created to build the capacity to assess and treat all shoulder problems accurately and with shortened wait times. Smarter communication with primary care practitioners, trained shoulder experts and collaboration with radiologists, physiotherapists and outside primary care groups allows shoulder problems to be treated with as little waste to the patient as possible. Eventually, our goal is to fulfill the Ministry of Health mandate to provide the right care at the right place.

The formation of a publicly-funded, innovative care model would not be possible without the partnership between Lakeridge Health team of surgeons and the Ajax Pickering Hospital Foundation. This group plans on measuring the effect of changes in wait times, imaging utilization and sharing their learnings to apply successful strategies in reforming other areas of specialty care.

Our first goal in creating The Shoulder Centre is to decrease the time taken to diagnose shoulder conditions and provide rational, evidence-based treatment program. As part of that goal we focus on providing education to patients and family members on the causes of common shoulder issues so that patients can participate in their care actively. In addition, the practitioners in The Shoulder Centre use up-to-date clinical research to guide patient decision-making.

Imaging at Lakeridge Health is an important element of the care The Shoulder Centre provides. We have created a strong bond with our Diagnostic Imaging department and have access to ultrasound and MRI, including urgent imaging when required.
