The SAIL Fusion system is intended to treat lower back pain that originates in the sacroiliac joint. This device fuses the sacrum to the pelvis, which addresses the degenerative joint changes and alleviates one of the leading causes of lower-back pain.

This innovative treatment for sacroiliac joint dysfunction is not yet available in the United States. News of regulatory clearances will be made available through this site.

Dysfunction in the sacroiliac joint ("SI joint") can cause lower back and/or radiating leg pain. Recent research shows that SI joint pain accounts up to 30% of lower back pain¹. These symptoms can present in a similar way to lumbar disc herniation ("sciatica"), and it can be difficult for doctors to tell the two sources of pain apart. As a result, SI joint pain is frequently misdiagnosed, leading to many unnecessary lumbar fusions.

The pain associated with SI joint dysfunction can be worsened by climbing, extended walking or standing, extra weight on a single leg, or carrying extra weight. Common causes include arthritis, pregnancy, prior lumbar spine surgery, and traumatic injury.²

A medical examination by a qualified physician is required to accurately diagnose SI joint dysfunction. In addition to reviewing your medical history, they may utilize physical manipulations, medical imaging, or injections to identify or rule out sources of pain.
