Sacroiliac joint dysfunction
Sacroiliac Joint Dysfunction
Sacroiliac Joint Dysfunction (pronounced: SAY-kro-ILL-ee-ak joint dis-FUNK-shun), also known as SI joint dysfunction, is a condition that causes chronic pain in the sacroiliac joints. These joints are located at the base of the spine, where the sacrum (the last segment of the spine) connects to the ilium (the largest part of the pelvic bone).
Etymology
The term "sacroiliac" is derived from the Latin words "sacrum" meaning sacred bone and "ilium" meaning flank or hip. "Dysfunction" comes from the Greek word "dys" meaning bad or difficult, and "function" meaning work or activity. Thus, sacroiliac joint dysfunction refers to the improper working of the joints connecting the sacrum and ilium.
Symptoms
Symptoms of sacroiliac joint dysfunction may include lower back pain, pain in the buttocks or posterior thigh, and difficulty sitting in one place for too long due to discomfort. The pain is often worsened by standing or walking for extended periods.
Causes
Sacroiliac joint dysfunction can be caused by a variety of factors, including pregnancy, trauma, arthritis, or infection. During pregnancy, the body releases hormones that allow the ligaments in the pelvic area to relax, which can lead to increased stress and wear on the sacroiliac joints.
Treatment
Treatment for sacroiliac joint dysfunction typically involves a combination of physical therapy, medication, and possibly surgical intervention. Physical therapy exercises can help strengthen the muscles around the sacroiliac joint and improve flexibility. Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce inflammation and pain.
