Sacroiliac Joint Pain Syndrome and Its Symptoms - Orthopedics

Sacroiliac Joint Pain Syndrome (SIJPS) is a condition that affects the sacroiliac joint, which connects the lower spine to the pelvis. This joint plays a crucial role in transferring weight and forces between the upper body and the legs. When the sacroiliac joint becomes inflamed or dysfunctional, it can lead to significant pain and discomfort, often felt in the lower back, buttocks, and sometimes radiating down the legs.

Your symptoms, including persistent pain in the sacroiliac region for six months, suggest that you may be experiencing SIJPS. The condition can be caused by various factors, including poor posture, repetitive stress, trauma, or underlying inflammatory conditions such as ankylosing spondylitis (AS), which is what your rheumatologist has diagnosed you with. AS is a type of inflammatory arthritis that primarily affects the spine and can lead to the fusion of vertebrae over time.

Regarding your question about inflammatory markers such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), these tests are commonly used to assess inflammation in the body. In patients with inflammatory conditions like ankylosing spondylitis, it is not uncommon to see elevated levels of CRP and ESR. A CRP level of 1.5 mg/dL is considered elevated, and an ESR of 40 mm/h is also indicative of inflammation. However, it is essential to note that not all patients with sacroiliac joint pain or even ankylosing spondylitis will have elevated inflammatory markers. Some individuals may have normal levels despite having significant symptoms.

In the case of SIJPS, the inflammation may not always be as pronounced as in other inflammatory arthritides, and the pain can be more related to mechanical dysfunction rather than systemic inflammation. Therefore, while elevated CRP and ESR can support a diagnosis of an inflammatory condition, their absence does not rule out SIJPS or other related disorders.

For management, physical therapy is often recommended to strengthen the muscles around the sacroiliac joint and improve flexibility. However, if you have not found relief through rehabilitation, it may be beneficial to explore other treatment options. These can include:
1. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation. In some cases, corticosteroid injections into the sacroiliac joint may provide significant relief.

2. Manual Therapy: Techniques such as chiropractic adjustments or osteopathic manipulation may help restore proper alignment and function to the joint.

3. Exercise: Engaging in specific exercises designed to stabilize the pelvis and strengthen the core can be beneficial. A physical therapist can tailor a program to your needs.

4. Lifestyle Modifications: Addressing posture, ergonomics, and activity modifications can help reduce strain on the sacroiliac joint.

5. Surgery: In rare cases where conservative treatments fail, surgical options such as sacroiliac joint fusion may be considered.

It is crucial to work closely with your healthcare provider to determine the best course of action based on your specific symptoms and overall health. If you are seeking a second opinion, consider consulting with an orthopedic specialist or a pain management specialist who has experience with sacroiliac joint disorders. They can provide additional insights and treatment options tailored to your condition.
In summary, while your elevated inflammatory markers may suggest an underlying inflammatory process, they do not definitively diagnose SIJPS. A comprehensive evaluation and a multidisciplinary approach to treatment are essential for managing your symptoms effectively.
