What is a sacroiliac joint injection?
Sacroiliac joint injection is an injection into a large joint called the sacroiliac joint, which is a joint that is in the low back towards the buttocks and it is bilateral. The joint serves as a fusion between the iliac bone and the sacral bone. It is a common source of low back pain where the lumbar back is not involved. This is easily diagnosed mostly with clinical exam and also radiological studies and MRIs. Injections to this area are also guided with x-ray machine with a needle guided into the joint and providing cortisone and local anesthetic. A series of one to three injections will be usually very beneficial to diagnose and treat this pain.
