The sacroiliac joint is located at the bottom of the spine, where it joins the pelvis, allowing for movement and helping stabilise the spine. Wear and tear, inflammation and injury to the area may cause pain in some people.
Injections to the sacroiliac joint may be used to help diagnose and treat certain types of back pain ,where simpler measures have not helped, by reducing some of the pain signals from the joint. Again, the effects can vary from person to person, with some experiencing significant and long-lasting relief. The injection contains local anaesthetic often with a small amount of steroid, and is usually undertaken alongside other treatments, such as physiotherapy.
