What is Sacroiliitis
and How is it Treated?

The sacroiliac joints are found where the spine meets the pelvis. Sacroiliitis is a painful condition where either one or both of the sacroiliac joints become inflamed. Lower back, buttock or groin pain associated with sacroiliitis can be difficult to distinguish from other types of back pain, which is why it’s important to see a spine expert to obtain a proper diagnosis as soon as your symptoms begin to show.

How Do I Know if I Have Sacroiliitis?

Sacroiliitis is a condition in which there is inflammation of one or both of the sacroiliac, or SI, joints. The two SI joints are where the upper and lower body meet. Specifically, the SI joints are where the lower portion of the spine connects to the pelvis. The primary function of the SI joints are to transfer weight from the upper body to the lower body.

Common Symptoms of Sacroiliitis

Symptoms of sacroiliitis commonly include pain in the low back, buttocks, or groin, which may extend down the legs and into the feet.

Other common symptoms of sacroiliitis include:

  • Pain that is aggravated by long periods of standing or climbing stairs.
  • Pain worsens when sitting for long periods of time or rolling over in bed.
  • Stiffness in the lower back and hips, especially when getting out of bed in the morning or after sitting for long periods of time. 
What Causes Sacroiliitis?

Infection and arthritis are common causes of sacroiliitis. Types of arthritis in the sacroiliac joint commonly include osteoarthritis and ankylosing spondylitis.

Other factors that contribute to developing sacroiliitis include: 

  • Trauma or injury such as a car accident or a fall that results in damage to the sacroiliac joint. 
  • Pregnancy/Childbirth
  • History of infections
  • Degeneration
