What is 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.
What causes Sacroiliitis?
Sacroiliitis may be caused by trauma or injury, like car accidents or falls that result in damage to the sacroiliac joint. Pregnancy can also cause sacroiliitis, as the sacroiliac joints stretch and loosen in preparation for childbirth. Other causes of sacroiliitis may include infection or arthritis. Types of arthritis in the sacroiliac joint commonly include osteoarthritis and ankylosing spondylitis.
Symptoms and Diagnosis
Symptoms of sacroiliitis commonly include pain in the low back, buttocks, or groin. This pain may extend down the legs and into the feet. This pain can be aggravated by extended periods of standing or by climbing stairs. This condition may be difficult to diagnose, as it can be difficult to distinguish from other types of back pain.
How is Sacroiliitis treated?
Treatment options for sacroiliitis are usually conservative in nature. Medication may be prescribed to help reduce inflammation. Your doctor may also prescribe rest, activity modification, physical therapy, or injections.
