The sacroiliac joint or SI joint (SIJ) is the place where the sacrum and the ilium meet. It is located just below the beltline, on both the left and right side where the hip meets the tailbone. This joint has a large nerve that extends through the joint and buttocks. When instable this joint can cause low back and leg pain. The primary role of the SI joint is to provide stability and act as a shock absorber for the spine and pelvis. It bears the load of the upper body when you stand, sit, walk or jump before the forces reach your legs. It is an essential component for energy transfer from the legs and the torso.

Common Symptoms

Low back pain is a common symptom that affects many people during their lifetime. For some, low back pain can be an acute, short-term problem. Others experience chronic, long-term symptoms that can limit mobility and effect their quality of life. Either way, the cause may or may not be your SI joint.

SI joint disorders require appropriate interpretation of your history, clinical exam results, and imaging studies. Often hip pathology and/or lumbar pathology can coexist with SI joint pathology. A healthcare provider trained in diagnosis and treatment can help diagnose your condition accurately and get you on the path for lasting relief.

To determine whether your pain is caused by your SI joint or another source, talk to a trained physician.

What is LinQ?

The LinQ SI Joint Stabilization System provides SI joint dysfunction patients with a minimally invasive option to combat pain. After a thorough diagnostic process, physicians may help alleviate, and in many cases eliminate, chronic pain by placing a single LinQ allograft into the SI joint. This single implant may help patients immediately regain joint stability – and with its large graft window, the LinQ SI Joint Stabilization System helps create an ideal environment for long-term fusion.
