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.
At the heart of everything we do at UHN are our Healthcare Professionals. Refer a patient to one of our 12 medical programs. Learn more about the resources and opportunities available for professional growth.
University Health Network has grown to be one of the largest research and teaching hospital networks in Canada - pioneers in improving the lives of patients. Our long history of health professions education at Toronto General, Toronto Western, Princess Margaret and Toronto Rehab hospitals has consistently advanced the science of education.
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.
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.
Dr. Angela M. Cheung founded the Osteoporosis Clinic & Research Program and continues to serve as Director of the Program. The clinic offers state-of-the-art diagnostic and expert care services to patients with osteoporosis and metabolic bone diseases, with a focus on fracture risk reduction and quality of life improvement. The Program serves over 3,000 patients annually and helped establish the Centre of Excellence in Skeletal Health Assessment – a group of bone diagnostic centres – in partnership with the Department of Medical Imaging at University Health Network and Mount Sinai Hospital. The Osteoporosis Program is one of the most productive osteoporosis programs in Canada, playing a key role in the development of novel diagnostic, preventative and treatment options for osteoporosis patients. The team has also taken a leadership role in developing guidelines and policies for osteoporosis care in Canada and North America.
Osteoporosis is a "silent" bone disease characterized by bone loss that makes bones weak and prone to fracture. Osteoporosis develops when the balance between bone formation and bone removal becomes skewed and bone is lost faster than it can be replaced. This can occur naturally due to: insufficient intake of bone-building nutrients such as calcium and vitamin D; low levels of estrogen in women after menopause; a general decline in bone health as a result of old age, or due to secondary causes such as taking medications that cause bone loss.
Donor support is key for the Osteoporosis Clinic and Research Program to continue its progress towards improving the lives of those affected by osteoporosis through increased understanding of the disease and better treatments. The following funding priorities have been identified:
Atypical Femur Fractures Project
Rare conditions such as Atypical Femur Fractures (AFFs) are unusual fractures of the femur (thigh bone) that are not well understood. Currently, we are following a cohort of 160 people who have suffered from this type of fracture. Funding is needed to conduct genetic analysis ($3000/patient) and determine the mechanical and structural factors associated with AFFs. Research scientists and graduate students are also required to analyze and interpret the data and biological samples.
New Diagnostic Equipment and Software
New equipment is now available which can better measure the mechanical properties of bone and will be invaluable in looking at who is at highest risk of fracture (Xtreme CT scanner 2 – cost $800,000). In addition, proprietary software for our current DXA machines can offer patients a better assessment of the structure and condition of their bones (cost $20,000/DXA machine x 10 machines). Personnel are required to study the use and effectiveness of new bone measuring software and devices.
Examining Biomarkers Representing High Risk for Fragility and Frailty
Osteoporosis patients who have a history of falls and are frail tend to sustain more fractures. More research is needed to determine individuals who are high risk of falling and better diagnostic tools and tests need to be explored to predict frailty. This is a critical area of research which needs to be funded in order to reduce the burden of osteoporosis on our aging population.
Studying the Relationship Between Bone and Muscle
An emerging area in osteoporosis research is the study of muscle loss with aging (sarcopenia) and how this relates to age-related bone loss. Future studies in this area will aim to determine which factors predict both sarcopenia and bone loss, and whether exercise and nutrition can play a role in prevention and treatment. The potential for medications to improve mobility and muscle function in order to prevent debilitating fractures will also be explored. Research scientists, post-doctoral fellows, graduate students, and research assistants interested in bone and muscle health will be required to run these new studies.
The Arthritis Program at University Health Network
The Arthritis Program at University Health Network is Canada’s largest multidisciplinary Arthritis Program with more than 80,000 outpatient visits annually. It has the largest division of arthritis clinical researchers in North America. There are four areas of focus: Osteoporosis, Orthopedics, Rheumatology, and the Hand Program. The Osteoporosis Program is recognized nationally and internationally for its unique approach to improving care for osteoarthritis patients.
