SI Joint Dysfunction Treatment in Chalfont, PA
Sacroiliac (SI) joint dysfunction is a common and often overlooked source of lower back and buttock pain. Our team offers evidence-based SI joint dysfunction treatment in Chalfont for pain that resists rest and general back care. Notably, the SI joints sit where the base of the spine meets the pelvis. As a result, the pain often mimics a disc or hip problem. In most cases, patients spend months chasing the wrong diagnosis. Therefore, we focus first on confirming the true pain source. Then we build a non-surgical, minimally invasive care plan around it.
✅ Pain in the lower back, buttock, or back of the hip, usually on one side
✅ Pain that spreads into the groin, thigh, or upper leg
✅ Discomfort that worsens with sitting, standing, or climbing stairs
✅ Sharp pain when rising from a chair or getting out of a car
✅ A sense of instability or "giving way" in the pelvis

What Causes SI Joint Dysfunction?
SI joint dysfunction develops when the joint moves too much or too little, or when the cartilage wears down. Often, no single event causes it. Instead, load, injury, and normal aging build up over time. As a result, the joint becomes irritated and sends pain signals. Because the triggers vary, our team reviews each patient's history before settling on a treatment plan.
Pregnancy and childbirth. These loosen the pelvic ligaments and shift how the joint carries load.
Trauma or injury. A fall or a motor vehicle accident can strain or damage the joint.
Prior lumbar fusion. Fusion adds stress to the joint below the fused segment.
Arthritis. This includes both wear-and-tear and inflammatory forms.
Repetitive stress. Lifting, twisting, or high-impact activity can gradually irritate the joint.
Understanding SI Joint Dysfunction
The sacroiliac joints are two small, strong joints in the pelvis. They connect the sacrum, the triangular bone at the base of the spine, to the hip bones. Normally, they move only slightly and transfer load between the spine and the legs. However, when a joint moves too much or too little, the surrounding ligaments and nerves become irritated. As a result, pain develops across the lower back, buttock, and hip.
Importantly, SI joint dysfunction is easy to miss. Research suggests the SI joint drives pain in roughly 15% to 30% of chronic low back pain cases. Yet the symptoms overlap with disc problems, hip arthritis, and sciatica. Consequently, many patients receive the wrong diagnosis for months or even years.
Our team takes a different approach. First, we listen to how and where the pain occurs. Then we use targeted exam tests and, when appropriate, a diagnostic injection to confirm the joint as the true source. This step matters, because an accurate diagnosis drives everything that follows. Accurate diagnosis allows us to recommend treatments that are more likely to provide meaningful, lasting relief.
Minimally Invasive, Research-Supported Treatments
Our approach focuses on minimally invasive treatments that help reduce pain, improve function, and support long-term recovery while avoiding unnecessary surgery whenever possible.
Image-Guided SI Joint Injections
Fluoroscopy-guided anesthetic and anti-inflammatory medication, placed directly in the joint to confirm the diagnosis and reduce pain.
*This is done outpatient and does not require anesthesia
Lateral Branch Radiofrequency Ablation (RFA)
A longer-lasting option that quiets the small nerves carrying pain signals from the SI joint.
*This is done outpatient and does not require anesthesia in most cases
Regenerative Therapies
Platelet-Rich Plasma (PRP) and prolotherapy for patients whose pain stems from loose, unstable ligaments.
*This is done outpatient and does not require anesthesia
FAQs
How do you know my pain is coming from the SI joint?
Is SI joint treatment surgery?
In most cases, no. We start with non-surgical, minimally invasive options such as injections and Radiofrequency Ablation (RFA). By contrast, surgery-style stabilization is reserved for the small number of patients who do not respond to these steps.
How long does relief from an SI joint injection last?
Relief varies from patient to patient. Some feel better for weeks, while others get several months of relief. When injections help but fade, RFA often makes that relief last much longer.
Can pregnancy cause SI joint pain?
Yes. Pregnancy loosens the pelvic ligaments and shifts your center of gravity, which stresses the SI joints. For lingering pain after pregnancy, regenerative options that address ligament laxity may be appropriate.
SI Joint Dysfunction Treatment in Chalfont: Minimally Invasive, Research-Supported Options
Image Guided Sacroiliac Joint Injections
For many patients, the first targeted step is an image-guided sacroiliac joint injection. Using real-time X-ray guidance (fluoroscopy), our team places a small dose of anesthetic and anti-inflammatory medication directly into the joint. This injection serves two purposes. First, it confirms the diagnosis, because significant relief points clearly to the SI joint. Second, it calms inflammation and reduces pain. In most cases, the anesthetic works within minutes, while the anti-inflammatory effect builds over the following days.
A diagnostic block that relieves pain by a clinically significant margin remains one of the most reliable ways to identify the sacroiliac joint as a pain source (Schwarzer et al., 1995).
Lateral Branch Radiofrequency Ablation
When injections help but the relief fades over time, Radiofrequency Ablation (RFA) offers a longer-lasting option. During this procedure, our team uses heat from a small probe. The probe interrupts the tiny lateral branch nerves that carry pain signals from the SI joint. As a result, the procedure quiets the pain signal at its source. Notably, the targeted nerves do not control muscle strength, so movement stays intact. For appropriate patients, relief can last many months before the nerves gradually regrow.
In a randomized, placebo-controlled study, lateral branch radiofrequency denervation produced significant improvements in pain and function for patients with sacroiliac joint pain (Cohen et al., 2008).
Regenerative Therapies for Joint Instability
Some patients develop SI joint pain because the supporting ligaments have loosened, often after pregnancy or injury. For these cases, regenerative options such as Platelet-Rich Plasma (PRP) and prolotherapy may help. Both treatments are intended to stimulate the body’s natural healing response. Although research is ongoing, they may help improve pain and function in appropriately selected patients. Consequently, the joint may regain stability over time. Additionally, our team reviews each patient’s history and imaging to decide whether a regenerative approach is a reasonable fit.
A randomized study reported that platelet-rich plasma injections provided more durable pain relief than steroid injections for sacroiliac joint pain at three months (Singla et al., 2017).
SI Joint Stabilization for Refractory Cases
For the small group whose pain persists despite injections and RFA, minimally invasive SI joint stabilization may help. This procedure supports the joint to limit painful motion. Importantly, our team discusses candidacy carefully and only after less invasive options have been fully explored.
Common Causes of SI Joint Dysfunction
- Pregnancy and childbirth. These loosen the pelvic ligaments and shift how the joint carries load.
- Trauma or injury. A fall or a motor vehicle accident can strain or damage the joint.
- Prior lumbar fusion. Fusion adds stress to the joint below the fused segment.
- Leg length differences or gait problems. These unevenly load one side of the pelvis.
- Arthritis. This includes both wear-and-tear and inflammatory forms.
- Repetitive stress. Lifting, twisting, or high-impact activity can gradually irritate the joint.
Common Symptoms
- Pain in the lower back, buttock, or back of the hip, usually on one side.
- Discomfort that spreads into the groin, thigh, or upper leg.
- Symptoms that worsen with sitting, standing, or climbing stairs.
- Sharp pain when rising from a chair or getting out of a car.
- A sense of instability or giving way in the pelvis.
How We Diagnose It
We start with a detailed history and a hands-on exam.
Next, we perform provocation tests that stress the joint in specific ways.
When several tests are positive, we often add imaging to rule out other causes.
Finally, a diagnostic injection can confirm the SI joint as the pain source.
