Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

Ways You Can Help
Being touched by illness affects us in different ways. Many people want to give back to the community and help others. At UHN, we welcome your contribution and offer different ways you can help so you can find one that suits you.
The Newsroom is the source for media looking for information about UHN or trying to connect with one of our experts for an interview. It’s also the place to find UHN media policies and catch up on our news stories, videos, media releases, podcasts and more.
In collaboration with Dr. Karen Davis, we continue to explore the cortical changes that occur following peripheral nerve injury, repair and rehabilitation. We are currently studying neuroplasticity in patient with carpal tunnel syndrome and the changes that occur in the brain prior and following surgical decompression.

Dr. Baltzer’s current research endeavours include biomarker screening in the basal thumb osteoarthritis population, and health costing analysis of hand trauma patients in Ontario.
Dr. Baltzer is currently exploring the possibility of establishing a unique biomarker profile for the patient population suffering from basal thumb osteoarthritis. Systemic markers of inflammation and joint degradation are the present targets of interest, with joint-local markers potentially indicating possible targets for novel intra-articular therapy development.
In Ontario, hand trauma patients substantiate a significant portion of emergency visits, often requiring extensive and multidisciplinary care long after the initial trauma. The frequency and volume of healthcare utilization and resulting costs can be explored to improve the current model for which care is delivered to these patients.

Dr. Chan is an Orthopaedic Hand and Wrist Surgeon and a Clinical Investigator at the University Health Network.
Her current research focuses the use of advanced wrist imaging techniques for analysis of joint contact forces and the early detection of wrist cartilage biochemical and morphological changes (the “pre-arthritic” state) post-trauma and following surgical joint preservation interventions. This research has the potential to provide surgeons with a better understanding of surgical timing for arthritis prevention, to improve upon current surgical techniques, and determine how such interventions affect and improve wrist cartilage health.
