Regions and countries

Most of the AO Trauma Regional Boards govern a network of AO Trauma country chapters each led by a country council.

AO Trauma understands that regional diversity—culture, language, economics and health-care–systems makes management by a single regional board challenging. Country Chapters were introduced to ensure representation of the diverse needs of national groups and provide local members the opportunity to get involved with the most essential activities of AO Trauma.

Through AO Trauma Country Chapters, AO Trauma continually promotes its support for members at the global and local levels and maintains interaction with the local orthopedic trauma community and its aligned organizations.

In most regions, AO Trauma Country Chapters are in an advanced stage of development, creating an integrated network managed by elected Councils comprised of AO Trauma officers.

About AO Trauma

“The AO is a source of camaraderie and mentorship that has sustained and improved me throughout my career. It has allowed me to become incrementally better, in a welcoming yet demanding environment. My patients and I both owe a debt of gratitude to this organization.”
