Learn About SI Joint Dysfunction

Why does it hurt?

If you have low back pain, you are not alone. Up to 85% of all people do at some point in their lives.2, 3 It has been reported that over 20% of all chronic low back pain is due to sacroiliac (SI) joint dysfunction.1 Located in the pelvis where the iliac bone joins the sacrum, the SI joint helps stabilize your pelvis and bear the weight of your upper body. If it degenerates or becomes injured, the nerve endings in the SI joint can cause pain in your low back, pelvis, buttocks and legs.


True SI Joint Arthrodesis

The SImmetry System follows accepted orthopedic spine principles designed to ensure optimal patient outcomes. The proprietary SImmetry Decorticator™ allows you to prepare the articular region of the SI joint, while other instruments facilitate collection of autologous bone, insertion of bone graft and placement of implants—in other words, a true arthrodesis.
