The AO story: transforming surgery—changing lives
The AO began with a problem: how to improve patient outcomes in the treatment of trauma and musculoskeletal disorders. Today, this remains the priority for everyone at and involved with the AO. The AO covers different specialist areas, brought together into one global community, one network, one powerhouse of excellence focused on improving patient care.
The AO is the premier innovator in the surgical treatment of bone fractures and disorders. Innovation at the AO goes from bench to bedside, including basic research, product development, clinical validation, and valorization.
Our global community
Today the AO has a global community of over 460,000 health care professionals.
Each year the AO offers 775 educational events around the world, supported by nearly 7,000 faculty and attended by over 98,000 participants.
The AO has over 18,000 surgeon members working in the fields of trauma, spine, craniomaxillofacial, veterinary, and reconstructive surgery.
In the years since the AO has founded, the work that we have done has had a profound impact on surgery, surgeons, ORP, and, crucially, on patient outcomes.
This video interview with AO Past President Nikolaus Renner, recorded during the AO's flagship educational event, the AO Davos Courses, in 2019, explores this impact.
