The sacroiliac joint connects the pelvis to the spine; it is considered to be the cause of back pain in patients with chronic low back pain in between 14% and 22% of cases.
Treatment is primarily conservative, based on physiotherapy and pain relieving/anti-inflammatory drugs. In resistant cases, intra-articular infiltrations, under ultrasound or fluoroscopic guidance, of slow-release cortisone, are an effective approach. In case of mechanical instability, the benefit may be temporary, in these cases it is possible to resort to sensory denervation of the sacroiliac joint with radiofrequency (RF) which can provide a long-lasting pain relief.
