Sacroiliac joint dysfunction is a condition that affects the sacroiliac joints, which connect the lower spine to the pelvis. It usually causes pain in the lower back and buttocks due to abnormal movement, inflammation, or degeneration of the joint.
This condition can lead to discomfort that may spread to the hips, groin, or legs, and it often becomes worse with certain movements like standing, walking, or climbing stairs. Although it can be painful, it is not caused by an infection and is not contagious.
Treatment for sacroiliac joint dysfunction focuses on reducing pain and improving joint stability, often through physical therapy, medications, or minimally invasive procedures. Medical evaluation is important when pain persists or affects daily activities, as proper diagnosis helps guide the best treatment approach.
Main symptoms
Sacroiliac joint dysfunction commonly causes pain in the lower body, especially around the pelvis and lower back. Other common symptoms include:
-
Lower back pain, usually on one side
-
Pain in the buttocks
-
Pain that may spread to the hips, groin, or thighs
-
Discomfort when standing up, walking, or climbing stairs
-
Pain that worsens after sitting or standing for long periods
-
Feeling of stiffness or reduced movement in the lower back
These symptoms can vary in intensity and may be mistaken for other causes of low back pain.
Possible causes
Sacroiliac joint dysfunction develops due to mechanical, inflammatory, or degenerative changes in the joint.
It can be caused by:
-
Joint instability or abnormal movement
-
Degeneration due to aging or wear and tear
-
Pregnancy, due to hormonal changes and increased joint mobility
-
Trauma, such as falls or car accidents
-
Previous spinal surgery, especially lumbar fusion
-
Inflammatory conditions, such as certain types of arthritis
-
Differences in leg length or posture problems
These factors can disrupt normal joint function and lead to pain.
Confirming a diagnosis
Diagnosis of sacroiliac joint dysfunction is mainly based on clinical evaluation. Doctors assess symptoms, medical history, and perform physical exams that involve specific movements to reproduce pain.
A group of physical tests, known as provocation tests, is often used. When several of these tests are positive, it increases the likelihood that the sacroiliac joint is the source of pain.
Imaging tests such as X-rays, CT scans, or MRI may be used to rule out other conditions. In some cases, a diagnostic injection with a local anesthetic into the joint can confirm the diagnosis if pain improves significantly.
Treatment options
Treatment usually starts with conservative methods and may progress depending on symptom severity.
1. Conservative treatment
Initial treatment focuses on reducing pain and improving joint stability. Physical therapy is often recommended to strengthen the core and pelvic muscles, which helps support the sacroiliac joint. Stretching exercises can improve flexibility, while manual therapy may help restore normal joint movement.
In some cases, a pelvic belt may be used to provide additional support and reduce strain on the joint. These approaches are often effective and are usually the first step in managing symptoms.
2. Medications
Medications can help control pain and inflammation, especially during flare-ups. Nonsteroidal anti-inflammatory drugs are commonly used to reduce swelling and discomfort, while other pain relievers may be taken as needed.
These medications are typically used alongside physical therapy rather than as a standalone treatment.
3. Interventional procedures
If symptoms do not improve with conservative care, more targeted treatments may be considered. Corticosteroid injections into the sacroiliac joint can help reduce inflammation and provide temporary pain relief.
Another option is radiofrequency ablation, a procedure that uses heat to interrupt pain signals from nearby nerves. These approaches aim to provide longer-lasting relief for people with persistent symptoms.
4. Surgical treatment
Surgery is usually reserved for severe cases that do not respond to other treatments. The most common procedure is minimally invasive sacroiliac joint fusion, which stabilizes the joint and reduces abnormal movement.
This option is generally considered only after other treatments have failed, as it involves a longer recovery period but may help relieve chronic pain.
Prevention measures
While not all cases can be prevented, certain measures may reduce the risk of developing and worsening sacroiliac joint dysfunction.
-
Maintaining good posture
-
Strengthening core and pelvic muscles
-
Avoiding repetitive strain on the lower back
-
Using proper techniques when lifting heavy objects
-
Staying physically active
These strategies help support joint stability and reduce stress on the lower back.
