Lower back pain is one of the most common musculoskeletal issues, affecting millions worldwide. However, not all lower back pain originates from the spine itself. One often overlooked cause is sacroiliac (SI) joint dysfunction, a condition that affects the joints connecting the spine to the pelvis.
SI joint dysfunction can mimic other spinal conditions, leading to misdiagnosis and ineffective treatments. Understanding the role of SI joint dysfunction, its symptoms, and how to differentiate it from other causes of back pain is essential for proper treatment and long-term relief.
What is the Sacroiliac Joint?
The sacroiliac (SI) joint is where the sacrum (the triangular bone at the base of the spine) meets the iliac bones of the pelvis. These joints play a crucial role in stability, weight distribution, and movement. They act as shock absorbers, transferring forces between the upper body and lower body during activities like walking, running, and lifting.
While the SI joint naturally has limited movement, dysfunction in this area can lead to pain and discomfort, affecting mobility and daily activities.
Causes of SI Joint Dysfunction
SI joint dysfunction can be caused by a number of factors, such as:
Injury or Trauma
A fall, accident, or sudden impact can damage the ligaments and muscles surrounding the SI joint, leading to inflammation and pain.
Arthritis and Degeneration
Osteoarthritis or ankylosing spondylitis (a type of inflammatory arthritis) can wear down the cartilage in the SI joint, leading to stiffness and chronic pain.
Pregnancy and Hormonal Changes
During pregnancy, hormonal changes loosen the ligaments around the SI joint, allowing more movement. This added flexibility, combined with the extra weight of pregnancy, can lead to SI joint pain.
Postural Imbalances and Muscle Weakness
Poor posture, uneven leg length, or muscle imbalances can put extra strain on the SI joint, leading to dysfunction over time.
Repetitive Movements and Overuse
Athletes and individuals with physically demanding jobs may develop SI joint issues due to repetitive stress on the area.
Symptoms of SI Joint Pain
SI joint dysfunction can cause localised pain and discomfort, often mistaken for other spinal conditions.
Common symptoms include:
- Pain in the lower back, buttocks, or hips, often felt on one side of the body.
- Pain that gets worse when you sit or stand for extended periods of time.
- Stiffness and reduced mobility, especially in the lower back and pelvic region.
- Pain that radiates down the leg, similar to sciatica but typically does not extend beyond the knee.
- Discomfort when walking, climbing stairs, or turning in bed.
These symptoms can make it difficult to carry out everyday activities, leading to frustration and reduced quality of life.
How SI Joint Pain is Mistaken for Other Spinal Conditions
SI joint dysfunction is often misdiagnosed as other lower back issues, such as:
1. Sciatica
Since SI joint pain can radiate down the leg, it is frequently mistaken for sciatica, which occurs due to nerve compression in the lower spine.
2. Herniated Disc
Both conditions can cause lower back pain and leg pain, but SI joint dysfunction usually does not involve nerve compression, which is a key characteristic of herniated discs.
3. Hip Disorders
Hip arthritis or bursitis can cause pain in a similar region, making diagnosis challenging without proper assessment.
Due to these overlapping symptoms, an accurate diagnosis is crucial for effective treatment.
Diagnosis and Identification
Self-Assessment Tests
If you suspect SI joint dysfunction, try these simple tests:
- FABER Test (Flexion, Abduction, External Rotation): Lie on your back and place your affected leg in a figure-four position. Gently press the knee downward. If pain occurs near the SI joint, it may indicate dysfunction.
- Standing SI Joint Test: Stand and shift your weight onto one leg. If this causes pain in the lower back or pelvis, it could be due to SI joint irritation.
Medical Evaluation
A doctor may use a combination of physical exams, imaging tests (X-rays, MRI), and diagnostic injections to confirm SI joint dysfunction. An injection of numbing medication into the SI joint can help determine if the pain is coming from that area.
Treatment Options
Managing SI joint dysfunction often requires a combination of therapies to reduce pain and restore function.
Medication and Pain Management
The following options can offer temporary relief.
- Ibuprofen and other anti-inflammatory drugs can help lessen pain.
- Heat and cold therapy can relieve stiffness and inflammation.
- SI joint injections may be used for short-term pain relief in severe cases.
Physiotherapy
Physical therapy plays a crucial role in strengthening the core muscles, lower back, and pelvis to support the SI joint and improve stability. Therapists may also use manual therapy
techniques to realign the joint.
Non-Surgical Spinal Decompression Treatment
Non-surgical spinal decompression is an advanced treatment that helps relieve pressure on the spine and SI joint by gently stretching the spinal structures. This treatment enhances blood flow, reduces inflammation, and promotes natural healing.
Lifestyle Modifications
Making some changes in your daily life can help to manage the pain.
- Maintain Good Posture: Avoid prolonged sitting and ensure your workstation is ergonomic.
- Exercise Regularly: Low-impact activities like swimming and yoga help strengthen the lower back without straining the SI joint.
- Use Proper Lifting Techniques: Always bend at the knees rather than the waist to avoid stress on the SI joint.
So, if you experience persistent lower back pain, it is advised to consult a specialist to determine whether the SI joint is the underlying cause and explore non-surgical treatment options for long-term relief.
