Sacroiliac Joint Pain

 

Sacroiliac joint disorder and pain is discomfort arising from the SI joint. The sacroiliac (SI) joint is formed by the junction of the sacrum, a flat triangle shaped bone between the two iliac bones that comprise part of the pelvis. SI joint pain can result in low back, upper buttock, hip and upper leg pain.

 

Patients usually report pain most focused at their upper buttock region where some people have a little dimple on each side.

 

Pain is classically worsened after sitting for long peroids, and especially when getting up from a seated position.

 

Sacroilitis may be triggered by various types of arthritis, trauma, skeletal imbalances or also by certain autoimmune diseases that are associated with inflammatory arthritis, for example ankylosing spondylitis, psoriatic arthritis and many others.

 

Other potential triggers are pregnancy, lumbar fusion surgery, infection, insufficiency fractures of sacrum or tumors.

 

SI joint discomfort is very common and can be easily diagnosed and treated with a simple injection.  Accurate diagnosis requires numbing the joint and injecting steroid to determine if the patient has relief of pain of their usual pain.
