SI JOINT STABILIZATION
Inflammation or irritation of the SI joints may cause pain in the lower back, abdomen, groin, buttocks, or legs. Minimally invasive SI joint fusion is a procedure designed to stabilize the SI joints by grafting the sacrum to the ilium using instrumentation, bone graft, or both in order to fuse the bone, limiting movement.
SI Joint implants are intended to stabilize your sacroiliac joint and provide an environment for fusion (joining bones together into one solid structure) to occur.
The system uses a posterior approach with SI joint fusion, which has several advantages:
- Physicians can use a minimally invasive approach through a small incision.
- Insertion of the device causes minimal tissue disruption.
- Bone graft can be delivered within the device to promote a fusion.
The 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.
This unique procedure is minimally invasive and involves implanting one small bone allograft into the SI joint to stabilize and fuse the dysfunctional joint. The entire procedure is done through a single, small incision on the patient’s back. Patients leave the surgery the same day, shortly after this procedure and can usually resume daily living activities within a couple of weeks, depending on how well they are healing and based on physician’s orders.
What is the SI Joint?
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.
What is SI joint dysfunction?
Sacroiliac joint dysfunction generally refers to pain in the sacroiliac joint region that is caused by abnormal motion in the sacroiliac joint, either too much or too little motion due to the lack of support from the once strong and taut ligaments.
Common problems of the sacroiliac joint are often called sacroiliac joint dysfunction (also termed SI joint dysfunction; SIJD). Your physician may also refer to sacroiliac joint pain by other terms like sacroiliitis, SI joint degeneration, SI joint inflammation, SI joint syndrome, SI joint disruption, SI joint insufficiency, SI joint strain and arthritis.
