1 AO Foundation Education Kevin Newman St Peter‘s Hospital, Chertsey, Surrey, UK 1958−2008 History of the AO

2 The inspiration for AO Maurice Müller Bern, Switzerland (1918−) met a former soldier who had received a femoral nailing by Gerhard Küntscher Kiel, Germany (1900−1972) military surgeon

3 The early years Maurice Müller resident of Liestal, Switzerland (1918−) was on a fellowship in Holland with Cornelis Pieter van Nes Leiden, Netherlands (1897−1972) who advised him to visit Robert Danis in Bruxelles

4 Compression plating Robert Danis Bruxelles, Belgium (1880−1962) “Théorie et Pratique de l’Osteosynthèse” coapteur plate for rigid fixation Compression for “per primam” healing Absence of callus “soudure autogène”

5 First results of ORIF Maurice Müller Fribourg, Switzerland 75 patients stable fixation early mobilization no complications

6 Old army friendships Robert Schneider Maurice Müller

7 Documenting trauma Lorenz Böhler Wien, Austria (1885−1973) Accident Hospital 241,000 trauma x-rays

Compromised (careful standard fixation possible) 2. Partial degloving (indirect reduction required) 3. Soft tissues destroyed (reconstruction essential)
