The OOT – Open Operating Theatre - was initiated in 2005 by the founder and editor-in-chief of the European Spine Journal (1991-2014) and the editor of MEM MEDIA Foundation in Rubigen, Switzerland, an independent non-profit organization. OOT is a surgical library presented on a video streaming platform. OOT is dedicated to spine surgery and features a variety of contents, mainly curated surgical videos, but also Master Lectures, Webinars, Seminars etc. aimed to focus on postgraduate and continuous education. The videos are produced according to a structured educational concept and are performed in close cooperation with international, experienced spine surgeon-teachers. The videos demonstrate how established, new and innovative surgical techniques can be approached in different ways by different surgeons, allowing the viewer to compare a surgery technique with his own technique when facing a similar problem. Leading surgeons present new surgical methods and tricks which the viewers can implement in their daily practice. The OOT library is continuously expanding with new videos. After online registration and subscription for a modest fee to support the operation of the platform , you can watch the videos anytime, anywhere and as many times as you prefer.
