Dennis Winge Hallager

Dennis Winge Hallager is a Clinical Associate Professor at the Department of Clinical Medicine, University of Copenhagen, and affiliated with the Orthopaedic Department at Zealand University Hospital in Køge since August 2023.

His academic qualifications include:

• Ph.D. in Adult Spinal Deformity Classification and Revision Risk- A Clinical and Biomechanical Study (University of Copenhagen, January 29, 2016)
• Cand.med. (equivalent to MD) from University of Copenhagen (January 22, 2010)

Dr. Hallager specializes in surgical treatment of degenerative spine diseases and osteoporotic fractures, with a strong focus on implementing evidence-based practice in orthopaedic surgery. His research bridges clinical biomechanics and real-world surgical outcomes to optimize patient care pathways.

His 25 publications (2021-2025) reveal a clear trajectory toward multicentre spine surgery research and evidence implementation science, featuring classification system validation, long-term fusion outcome studies, and quantifiable impacts of evidence-based guidelines on surgical rates (e.g., 68% reduction in distal radius fracture operations).

He supervises bachelor, master, and PhD students while contributing to academic discourse through peer review for journals like Acta Orthopaedica.
