A medical revolution
• 1958: Foundation of the „Arbeitsgemeinschaft für Osteosynthese / AO“ (Association for the Study of Internal Fixation) in Biel/Switzerland by 13 visionary surgeons
• Revolution in trauma care and treatment of musculoskeletal disorders worldwide
• Principles of osteosynthesis: - established by those pioneers - further developed over the past 50 years- today: golden standard in modern trauma and orthopedic surgery

Are fragility fractures common?
Age = 50, lifetime risk♀ > risk of breast, ovarian &
uterine cancer♂ > risk of prostate cancer
Age > 50• 1:2 ♀ and 1:5 ♂ will suffer from a
fracture in the remaining life time• 55% have a low bone mass
increased risk of fracture
