Sacroiliac Joint Dysfunction

The sacroiliac (SI) joint, located on either side of the lower back where the sacrum (triangular bone at the base of the spine) connects to the ilium (top of the pelvis), plays an important role in stability, weight distribution, and shock absorption during movement. When these joints become damaged or inflamed, they can cause pain and discomfort in the lower back, hips, and legs, affecting daily activities and quality of life. This condition is known as sacroiliac joint dysfunction, also known as sacroiliitis or sacroiliac joint syndrome.

What are the Causes?

Several factors can contribute to the development of sacroiliac joint dysfunction:

Mechanical stress: Activities that put a lot of pressure or stress on the SI joint, such as heavy lifting, repetitive bending, twisting, or standing for long periods of time, can contribute to dysfunction.

Pregnancy: Hormonal changes during pregnancy can loosen the ligaments around the SI joints, increasing their mobility and possibly causing pain.
Age-related changes: As we age, the cartilage in the SI joints wears down, making them more prone to inflammation and wear and tear.
Leg length difference: Even a slight difference in leg length can alter gait mechanics and put unequal stress on the SI joints.
Previous injuries: Injuries to the pelvis, lower back, or legs can damage the SI joints or surrounding structures, increasing the risk of disability.
Underlying conditions: Certain medical conditions such as rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis can also involve inflammation of the SI joint.

Sacroiliac joint disorders signs and symptoms

The most common symptom of sacroiliac joint dysfunction is pain felt in the lower back, hips, and sometimes radiating down the leg. Pain can be characterized as:

Low back pain: A constant, throbbing pain in the lower back or buttocks.
Sharp pain: Sudden, stabbing pain that may worsen with certain movements or positions.
Pain with specific movements: Activities such as climbing stairs, getting out of bed, or standing for long periods of time can increase the pain.
Pain that is referred to the leg: In some cases, the pain can radiate to the back of the thigh, mimicking sciatica pain.

Other possible symptoms may include:

Stiffness: Difficulty bending forward, turning, or standing up straight due to pain and stiffness in the lower back.
Clicking or popping sounds: In some cases, individuals may experience clicking or popping sounds with movement in the lower back.
Pain with specific movements: Activities such as climbing stairs, getting out of bed, or standing for long periods of time can increase the pain.
Pain that is referred to the leg: In some cases, the pain can radiate to the back of the thigh, mimicking sciatica pain.

It is important to note that these symptoms can be caused by a variety of other conditions, and a healthcare professional should be consulted for an accurate diagnosis.

Diagnosis of Sacroiliac Joint Dysfunction

History and Physical Examination: A thorough assessment is crucial.
Positive Provocation Tests: At least three out of five positive tests (such as Gaenslen, thigh thrust, distraction, compression, and sacral thrust) suggest SI joint dysfunction.
Local Anesthetic SI Joint Blocks: These can confirm the SI joint as the source of pain.

What are the Treatment Options?

Conservative treatment:

Sacroiliac joint dysfunction is usually managed with a conservative approach, focusing on pain management, reducing inflammation, and improving joint function. These methods often include a combination of the following:
Rest: Although complete bed rest is not recommended, avoiding strenuous activities that aggravate pain may be beneficial in the early stages.
Pain medication: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage pain and inflammation. In some cases, stronger pain medication may be prescribed by a healthcare professional.
Physical therapy: Physical therapy plays an important role in the management of sacroiliac joint disorders.
Manual therapy techniques: Techniques such as massage therapy, joint mobilization, and manipulation can be used to improve joint mobility, reduce stiffness, and reduce muscle tension.
Heat or ice treatment: Applying heat or an ice pack to the affected area can help control pain and inflammation. Heat is often preferred for stiffness, while ice can be helpful for severe pain.
Bracing or support: In some cases, wearing a sacroiliac joint brace or support belt can provide temporary pain relief and support during certain activities.

Other possible interventions:

Injections: Injections of corticosteroids or local anesthetics directly into the SI joint can provide pain relief, although their long-term effectiveness is limited.

Acupuncture: This traditional Chinese medicine practice may offer some pain relief benefits, although more research is needed to confirm its efficacy.

Surgery:

Sacroiliac joint fusion surgery is generally considered a last resort for individuals with severe and persistent pain that has not responded adequately to conservative treatment. This surgery involves fusing the SI joint to prevent further movement and possibly reduce pain.
