The sacro-iliac joint is situated inside the pelvis, between the tailbone (sacrum) and the pelvis bones (ilia). It is predisposed to degenerative issues (osteoarthritis of the sacroiliac joint), inflammatory conditions (ankylosing spondylitis and others), or trauma. The most common traumatic events for the sacro-iliac joint complex are labor and delivery, car accidents, or the aftermath of lumbar surgical fusion.
Traditionally, pain from the sacroiliac joint is diagnosed and sometimes treated with injections into the joint. Careful diagnosis will have to differentiate between lumbar spine pain sources, hip joint pain, piriformis muscle pain, and sacro-iliac joint pain. This is especially important after lumbar spine fusion, when it is estimated that up to 40% of patients develop sacro-iliac joint problems.
Sacroiliac joint injury or degeneration is treated with regenerative techniques, such as proliferative therapy (prolotherapy), platelet-rich plasma and stem cell injections. Some patients go on to have a surgical fusion of the joint.
