The SI joint is the link between the ilium in the pelvis to the sacrum, which is the lowest part of the spine above the tailbone.

A dysfunctional SI joint may inflame the joint and surrounding nerves causing pain in the lower back, hip, groin, or pelvis.

SI joint pain can mimic pain in the lower back, hip, groin, or pelvis.

Patients who suffer from SI joint dysfunction can have severe pain when performing transitional movements like standing from a chair.

Patients who have SI joint pain usually find it difficult to sit for long periods of time, and usually try to alleviate the discomfort by sitting on the least effected side.

The iFuse TORQ Implant System is designed to provide stabilization and fusion for certain SI joint disorders.
