The Swiss town of Davos is famous for mountain slopes, winter sports and the annual meeting of the World Economic Forum. But did you know that it also attracts scientists and doctors from all over the world? In this six-part video series, SWI swissinfo.ch journalists Sara Ibrahim and Michele Andina take you on a journey to discover five of Davos’s research institutes.

In this first episode, they take you to the AO Davos Courses, a two-week training congress for surgeons learning to treat bone fractures. In hands-on workshops and online live surgeries, experts explain how to master everything from trauma surgery to prosthetics and joint replacement. Participants then practise 3-D models with drills and screws.
