Our People – Hand​

Summary

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.

Summary

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.

Keywords

Wrist kinematics and biomechanics; advanced wrist bioimaging; patient-reported outcomes

Summary

Barbara Jemec is a Surgeon Educator and the Educational Lead for Plastic Surgery in the Hand Program at Toronto Western. As such she is part of the Canadian Resident Matching Service and the University of Toronto Residency Program Committee.

Her clinical research interest lies in improving outcomes and tailor-making the treatment for Dupuytren’s disease. She is passionate about Global Surgery and established the national plastic surgery foundation for education in plastic reconstructive surgery in the UK. She continues to have strong ties to the Global Surgery community since her re-location and is enormously proud to be on the organizing committee of the international Global Health Bethune Roundtable conference, which in 2023 is held in Toronto.

Barbara Jemec was originally born in Copenhagen, Denmark and graduated in medicine from Copenhagen University in 1991, before relocating to England, UK where she trained and worked in the National Health Service for 30 years, including 17 years as a staff plastic surgeon in London, UK, before she moved to Toronto in 2021.
