The sacroiliac joint is a source of pain in up to 30% of patients with chronic low back pain. In many cases the symptoms are attributed to incidental findings of coexisting degenerative spinal lesions, resulting in unnecessary and ineffective epidural steroid injections.

Typically these patients, middle-aged and older as well as women before and after childbirth, usually present with pain below the level of the lumbar vertebrae with reflection in the buttock and lower extremity. Many times they are able to locate with their finger the area of maximum sensitivity at the level of the lower border of the sacroiliac joint.

The trained Pain medicine doctor can make the above diagnosis possible with an ultrasound examination in combination with special clinical tests.

Ultrasound-guided intra-articular injection of appropriate solutions works diagnostically and therapeutically and is performed with relative precision easily in an office environment, avoiding the radiation of its alternative fluoroscopic intervention and allows the combination with lateral sacroiliac plexus block and prolotherapy of the ligaments of the area for desensitization and stabilization.
