Stephan M. Perren is Senior Scientific Advisor of the AO-Foundation in Òsemi retirementÓ. He acted about 30 years as Director of the AO Research Institute in Davos. After training and boards as a surgeon with special interest in bone fracture treatment, he took up clinically oriented biomechanical research. He studied the biological reaction of repair tissues of fractured bone to physical input. His interdisciplinary team analyzed biology and biomechanics of implants used for surgical fixation of fractures. Later his interest focused on the relevance of biological aspects in fracture treatment such as biocompatibility of different implant materials, their immunological effect and alterations of local resistance to infection, mainly in steel and titanium implants of different design. Since the early 1960s he is an addict of titanium for internal fixation implants.
