Sacroiliac Joint Treatment: Conservative and Surgical Options
Sacroiliac joint (SIJ) pain is a common source of lower back and pelvic discomfort. When left untreated, it can significantly impact daily activities and overall quality of life. At Complex Spine Institute, we provide a comprehensive, personalized approach supported by advanced diagnostics and top-tier surgical expertise.
Understanding the Sacroiliac Joint
The sacroiliac joint connects the sacrum (the base of the spine) to the iliac bones of the pelvis. It plays a vital role in stabilizing the body and transferring loads between the upper body and legs during activities like walking or standing.
When inflamed or dysfunctional—a condition known as sacroiliitis or sacroiliac joint dysfunction—it can cause low back pain, pelvic discomfort, or even radiating pain down the legs, mimicking sciatica.
Common Symptoms of SI Joint Dysfunction
- Unilateral pain in the lower back or buttock
- Worsening pain after prolonged standing or walking
- Stiffness or a feeling of locking in the pelvic region
- Pain while climbing stairs or rotating the trunk
Accurate Diagnosis Is Key
A precise diagnosis helps avoid ineffective treatments. At Complex Spine Institute, we use clinical evaluations and advanced imaging such as MRI, CT scans, and image-guided anesthetic blocks to confirm the pain source.
Dr. Vicenç Gilete utilizes dynamic imaging—flexion, extension, and rotation views—to detect subtle dysfunctions not visible in standard MRIs. This level of precision allows us to tailor treatment plans to each patient’s needs.
Conservative Treatment Options
Most cases are initially managed with non-surgical therapies, including:
- Specialized physical therapy to stabilize the pelvic region
- Anti-inflammatory medications and muscle relaxants
- Core-strengthening and pelvic-stabilizing exercises
- Image-guided SI joint injections with anesthetics and corticosteroids
- Regenerative therapies such as stem cells or platelet-rich plasma (PRP)
Dr. Augusto Covaro, an expert in conservative and minimally invasive approaches, evaluates each patient individually to determine the most effective care strategy.
SI Joint Block: Diagnostic and Therapeutic Tool
This procedure involves injecting a local anesthetic into the SI joint under imaging guidance. If the patient experiences temporary pain relief, it confirms the joint as the pain source. It can also be repeated as a periodic pain management technique.
When to Consider SI Joint Fusion Surgery
In cases of chronic, disabling pain that doesn’t respond to conservative treatments, SI joint fusion may be recommended. This minimally invasive procedure stabilizes the joint by surgically fusing it, eliminating painful movement.
Dr. Covaro performs this technique through tiny incisions, resulting in minimal blood loss and faster recovery. He is also a leading educator in this surgical method across Europe.

Benefits of Minimally Invasive SI Joint Surgery
- Minimal tissue damage
- Reduced postoperative pain
- Faster functional recovery
- Same-day discharge in most cases
