Join the ISAR Case Registry

The registration of surgical cases is helpful to understand the healing process and pros and cons of various new devices and technologies. And, moreover, surgeons and patients can participate and will be able to observe the benchmark of clinical outcome after SIJ fusion.

There's a reason why the majority of doctors do not consider sacroiliac joint fusion as a standard of care.

Prof. B. Meyer, M.D.

Right now, the SIJ fusion world is a total free for all that is using one approach (the 510(k) approach) with no one but industry in charge of educating the surgeons or providing oversight for the surgeries that are being performed. Complications do occur, and are currently managed in haphazard ways with no accountability to anyone. The one person who is really left out of the equation here is the patient.

Bruce Dall, M.D.

“It is wonderful that there is now an institution which tries to collect the data – which are very poor until now.

Prof. Dr. med. Jürgen Harms

I am really thrilled about the increased interest of my life commitment – the sacroiliac joint. You might know I have been working on the field since 1986. I am very glad to hear that several orthopedic surgeons are realizing the importance of the SI-joint. As well I think planning of a conference is extremely important to give it an important impact. The fate of the SIJ should be taken care of.

Dr. Bengt Sturesson

If the patient has two lesions and you only treat one, the patient will still be unhappy! You never think about the sacroiliac joint if you don't think about the sacroiliac joint.

Arnold Graham-Smith, M.D.

As an enthused participant I would like to give you a feedback on your meeting in Hamburg: The quality of lectures and discussions had been truly outstanding, it was worth the long travel. Being a manual physician as well as interventional pain therapist I really drew important benefit. Unfortunately until now only few collegues are considering this topic. I am very open to cooperate!

Dr. Markus Schneider, Orthopaedic and Trauma Surgeon

"I highly appreciate that an association is now dealing intensively with this problem which is an urging problem within the field of spinal pathologies - not only in the respect of surgical therapies. I consider it immportant that this - oftentimes mystifyingly approached - problem of SIJ now starts to enter the solid ground of natural science."

Prof. Dr. med. Jürgen Harms
