The sacroiliac joint is a common target field for physiotherapists since long. Nonsurgical therapy of SIJ dysfunction is the standard treatment and in the majority of cases very successful. Our association deals targets at a cooperation of surgeons and non-surgeons to evaluate the diagnosis algorithm to avoid surgery, but on the other hand find the right way to diagnose surgical level indication. Surgeons must be familiar with non surgical treatment, and physiotherapists should be aware of surgical options in case of chronic SIJ pain. We invite you to join our discussion.
