The sacroiliac joint is the junction between the sacrum and the ilium bones of the pelvis, which are connected by strong ligaments. Sacroiliac joint pain is often due to abnormal motion in this region. This may results in inflammation and pain of the SI joint. Patients with SI joint pain may complain of low back, buttocks, groin and hip pain. SI joint pain is often difficult to diagnose. Treatment options include medications and SI joint injections. More recently, the SI joint fusion procedure has been developed, which allows the practitioner to fuse the SI joint and prevent the friction that causes pain.
Recognizing the Signs of Pelvic and Lower Back Instability

The SI joint acts as a crucial shock absorber between your upper body and legs. When the supportive ligaments become damaged or degenerate, the resulting abnormal micro-motions lead to debilitating localized inflammation and nerve irritation.
Hormonal changes, prior physical trauma, or repetitive stress can weaken the strong ligaments holding the sacrum and ilium together, causing painful hypermobility.

Natural wear and tear over time can erode the protective cartilage within the joint space, leading to bone-on-bone friction and localized osteoarthritis.

Because SI pain closely mimics sciatica, highly precise, fluoroscopically guided numbing injections are utilized to pinpoint the exact origin of your discomfort.

Advanced interventional procedures use small titanium implants to stabilize the joint, eliminating the painful friction and restoring lasting structural integrity.

Expert Tip: Because sacroiliac joint dysfunction closely mimics lumbar disc herniation and sciatica, a thorough diagnostic workup utilizing image-guided anesthetic blocks is absolutely crucial before considering any surgical intervention.
