Presidential Message

Sacroiliac joint dysfunction has been neglected as a source of pain and even more as a surgical level indication since years. The development of new diagnostic tools, technologies and materials revealed the need to have a closer look at this unique joint from the surgical point of view. Pioneering this topic, SIMEG members are primarily dedicated to avoid surgery - but once the diagnosis is confirmed, we should be able to offer our patients the adequate treatment they need. In the course of three successful international conferences in Germany and the USA many questions were answered, but even more are still unsolved.

The question "Is SIJ-fusion a must have tool in the arsenal of a spinal surgeon?" was pro- and con debated by Prof. Bernhard Meyer from Munich, Germany and Jeff Donner, MD,  at the ICSJS 2016 in Hamburg, Germany. This year we are proud to welcome again internationally well renowned speakers like William Cross, Sonia Eden, Joseph Fortin, David Polly - just to mention a few. Furthermore we are looking forward to Steve Garfin's talk on "Spine surgeons neglegted the SIJ as a treatable pain generator for so many decades - what changed my mind!?"

SIMEG is building up work groups to find answers and to start educating the SIJ surgical topic unbiased - which also means until now unfunded. While working on those topics by dedicated SIMEG members, we are happy to introduce ourselves and to offer a discussion with spinal surgeons during our satellite symposium on the day before the ISASS19 in Anaheim, California, starts.

ISASS19 Banner

Anaheim has German roots, and so has SIMEG (founded in Germany in 2013). The city was founded in 1857 by 50 German-Americans who were residents of San Francisco and whose families had originated in Rothenburg ob der Tauber in Bavaria. Anaheim’s name is a blend of Ana, after the nearby Santa Ana River, and German -heim meaning “home”. Today Anaheim is a flourishing destination not just because of the Disneyland theme park with over 650 million visitors since its opening but also because of a lot of other attractions like the Convention Center, the Muzeo, the City National Grove, the GardenWalk and the Hills Golf Course just to mention a few of them.

We thank the ISASS board, especially president Marek Szpalski for this opportunity and we invite you to experience and support the transmission of knowledge among spinal and sacroiliac joint expert surgeons.
