AO Clinical Investigation and Documentation 's history

In 1959, Maurice E Müller, a founding member of the AO Foundation, created the AO Documentation Center to share experience and validate the AO methods. In 1967, the AO Documentation Center was formally registered in Bern, Switzerland, as a foundation for the purpose of collecting, analyzing, and evaluation of fracture handling/osteosyntheses.

In 1995, the AO Documentation Center was registered in Canton Graubünden and renamed AO Documentation and Publishing Foundation. In 1999, the foundation became AO Clinical Investigation and Documentation, with an updated purpose of conducting prospective studies and publishing educational materials and clinical investigation results.
