Sacroiliac joint osteoarthritis

About 25% of all cases of chronic back pain originate from osteoarthritis or chronic instability of the sacroiliac joints. The most common causes are injuries, pregnancies, or previous surgery. Typical of this disease are discomfort while sitting on the affected side, burning pain radiating to the thighs as well as special methods of investigation (FABER test, Patrick Kubis test, CT, MRI). If conservative therapy fails, DIANA, a minimally invasive surgical method is available for the surgical treatment of sacroiliac joint osteoarthritis. DIANA stands for Distraction Interference Arthrodesis with Neurovascular Anticipation and was developed by Dr. John Stark from Minneapolis. The principle of this operation is that the affected sacroiliac joint is stabilised with a special titanium interference screw from a minimally invasive rear approach, and is then stiffened, or fused, with bone implant.
