AO Spine Knowledge Forum Deformity
Creating a common language and framework for researchers and clinicians
AO Spine KF Deformity at the Global Spine Congress 2019 in Toronto, ON, Canada AO Spine KF Deformity aims to improve the care for patients with a spinal deformity by generating and disseminating meaningful and impactful clinical evidence.
They do this by engaging leading clinicians, researchers, and spine centers from around the world to perform evidence-based research and by disseminating the research findings and newfound knowledge through publications and presentations.
