SI Joint Dysfunction & Fusion Treatment
Persistent pain in the lower back, buttock, or pelvis can make it difficult to sit, walk, or stay active. When that pain comes from the sacroiliac (SI) joint, accurate diagnosis and the right treatment plan can provide a meaningful difference.
At DFW Sports Medicine, patients in McKinney and Frisco receive personalized care for musculoskeletal pain, including SI joint dysfunction. Our team emphasizes careful evaluation, conservative care when possible, and minimally invasive SI joint fusion when more advanced treatment is appropriate.
What Is the Sacroiliac (SI) Joint?
The sacroiliac joints connect the base of the spine (the sacrum) to the pelvis. There are two SI joints, one on each side, and they help transfer weight between the upper body and legs while stabilizing the pelvis.
The SI joints move only a small amount, but inflammation, irritation, or instability can still produce significant pain. Because SI joint pain can resemble other spinal or hip problems, it is often overlooked without a targeted evaluation.
What Are the Common Causes of SI Joint Pain?
Several issues can stress or irritate the SI joint over time. Common contributors include:
- Trauma or falls involving the pelvis or lower back
- Pregnancy and hormonal changes that affect ligaments
- Degenerative arthritis in and around the joint
- Prior lumbar spine surgery
- Repetitive stress from sports or physical work
- Gait changes or leg-length differences
Some patients can recall a specific injury; others develop symptoms gradually from wear and altered joint mechanics.
What Are Common Symptoms of SI Joint Dysfunction?
SI joint dysfunction often causes one-sided low back or buttock pain. Symptoms may also include:
- Pain over the back of the pelvis, often just below the belt line
- Discomfort that can radiate into the hip or thigh
- Pain that worsens with standing, walking, stairs, or getting out of a chair
- Tenderness when pressing over the SI joint region
Because these symptoms overlap with lower back pain, sciatica, and hip problems, it is important not to assume the source of pain. A clear diagnosis helps ensure treatment is focused on the true pain generator.
How Is SI Joint Dysfunction Diagnosed?
Diagnosing SI joint pain requires more than one test. Your provider usually relies on a combination of:
History and physical examination
Your visit starts with a detailed discussion of your symptoms, including where you hurt, how long the pain has been present, and what makes it better or worse. A focused physical exam includes specific maneuvers designed to stress the SI joint and see whether they reproduce your pain.
Imaging studies
X-rays, CT scans, or MRI may be ordered to evaluate the spine, pelvis, and hips. Imaging helps your provider look for arthritis, fractures, or other structural problems and can help rule out alternative causes of your symptoms.
Diagnostic SI joint injections
DFW Sports Medicine notes that fluoroscopy-guided SI joint injections can be used for diagnostic purposes. When numbing medication is placed directly into the SI joint, it significantly relieves pain for a short time and supports the idea that the joint itself is playing a role in your symptoms.
Conservative Treatment Options for SI Joint Dysfunction
Most patients begin with non-surgical treatment. At DFW Sports Medicine, conservative care for SI joint dysfunction may include:
- Activity modification:Limiting or adjusting movements that consistently aggravate the joint.
- Physical therapy:Exercises to strengthen the muscles supporting the pelvis and improve stability, flexibility, and overall mechanics.
- Targeted pain relief:Anti-inflammatory strategies and other measures to calm irritated tissue.
- SI joint injections:Image-guided injections used to diagnose and treat SI joint-related pain.
Many patients experience meaningful relief with a combination of therapy, home exercises, and appropriately timed injections. Surgery is reserved for carefully selected patients who do not improve enough with these approaches.
What Are the Roles of Diagnostic and Therapeutic SI Joint Injections?
SI joint injections serve two important roles.
Diagnostic role
A diagnostic injection uses numbing medication to see whether temporarily blocking the SI joint decreases your pain. Significant short-term relief suggests the joint is a major source of symptoms and helps guide further treatment decisions.
Therapeutic role
A therapeutic injection uses a combination of numbing medication and anti-inflammatory medication to help reduce joint irritation. For some patients, this provides relief that allows them to participate more fully in physical therapy and daily activity.
Injections are typically a component of a broader plan rather than a stand-alone solution. They may be repeated when appropriate, but they are not intended as a form of indefinite treatment.
When Is SI Joint Fusion Surgery Considered?
Minimally invasive SI joint fusion may be considered when chronic SI joint pain does not respond adequately to conservative care. This option is typically reserved for patients who:
- Have symptoms and exam findings consistent with SI joint dysfunction
- Have undergone imaging and other evaluations to rule out alternative causes
- Experience meaningful but temporary relief from a diagnostic SI joint injection
- Continue to have pain and functional limitation despite appropriate therapy, activity modification, and injections
The goal of SI joint fusion is to stabilize the joint and reduce painful motion. The decision to proceed is always individualized, based on your diagnosis, overall health, and treatment goals.
What Are the Benefits and Risks of Minimally Invasive SI Joint Fusion?
Minimally invasive SI joint fusion is designed to address SI joint pain through smaller incisions and less soft tissue disruption than traditional open surgery.
Possible benefits
While individual results vary, possible benefits may include:
- Smaller incisions compared with traditional surgery
- Limited disruption of surrounding muscles and soft tissues
- Improved stability along the SI joint
- The possibility of reduced pain and improved function in appropriately selected patients
Possible risks
All surgery involves risk. Possible risks of SI joint fusion include:
- Infection or bleeding
- Nerve irritation or injury
- Incomplete pain relief
- Problems related to anesthesia
- Failure of the joint to fuse properly or need for additional treatment
We will review the possible benefits and risks in detail during your consultation, so you can make an informed decision.
What Is Recovery Like After SI Joint Fusion?
Recovery after SI joint fusion is a stepwise process. The precise timeline depends on the specific procedure, your health, and your activity demands.
In general, patients can expect:
- An early healing phase focused on protecting the surgical area
- Gradual return to walking and basic daily activities
- Possible use of an assistive device for a period after surgery
- A structured progression of activity based on your surgeon’s guidance
Physical therapy may be recommended as you advance through recovery to help restore strength and mobility in a controlled way. Because every patient heals at a different pace, it is important to follow your provider’s instructions rather than comparing your experience to someone else’s.

Frequently Asked Questions
Where is SI joint pain usually felt?
SI joint pain is most often felt on one side of the lower back or buttock, just below the belt line. It can spread into the hip, groin, or back of the thigh, and it frequently worsens with standing, walking, climbing stairs, or getting up from a chair.
Can SI joint dysfunction go away on its own?
Mild SI joint irritation sometimes settles with rest, activity changes, and time. Persistent or recurring pain usually needs a focused evaluation, since ongoing dysfunction tends to respond better to a structured plan of physical therapy, activity modification, and, when appropriate, image-guided injections.
Is minimally invasive SI joint fusion an outpatient procedure?
Minimally invasive SI joint fusion is often performed through small incisions and, for many patients, does not require an extended hospital stay. Your care team will confirm the specifics for your situation, including anesthesia and recovery, during your consultation.
Is SI joint fusion covered by insurance?
Coverage varies by plan and by the documentation that supports medical necessity, such as a positive diagnostic injection and a trial of conservative care. Our team can help you understand your benefits and what is typically required before the procedure is approved.
What activities tend to make SI joint pain worse?
Many patients notice more pain with prolonged standing, climbing stairs, rising from a seated position, or lying on the affected side. Identifying the movements that consistently aggravate your pain helps guide activity changes and physical therapy.
Can SI joint problems cause hip or leg pain?
Yes. Because the SI joint sits where the spine meets the pelvis, pain from the joint can radiate into the hip, groin, or thigh, and it is often mistaken for a hip condition or a pinched nerve. A targeted exam helps separate SI joint dysfunction from hip pain and spine conditions.
