Do you have SI Joint Pain?
Understanding Causes, Symptoms, and Treatment
The SI joint can be a significant cause of lower back pain. Clinical publications have identified the SI joint as a pain generator in 15-30% of chronic lower back pain patients. In addition, the SI joint is a pain generator in up to 43% of patients with continued or new onset lower back pain after a lumbar fusion.
What Is the SI (Sacroiliac) Joint?
The sacroiliac joint (SI joint) is located in the pelvis; it links the iliac bones (pelvis) to the sacrum (lowest part of the spine above the tailbone). It is an essential component for energy transfer between the legs and the torso.
Like any other joint in the body, the SI joint can be injured and/or undergo degeneration. When this happens, people can feel pain in their buttock and sometimes in the lower back, hips and legs. This is especially true while lifting, running, walking or even lying on the involved side.
Common Symptoms of SI Joint Pain
Sacroiliac Joint Fusion with the iFuse Implant System
The iFuse Implant System is designed to stabilize and fuse the SI joint. The iFuse procedure involves inserting typically three triangular-shaped titanium implants across the sacroiliac joint to maximize SI joint stability, reduce pain, and improve function. The procedure is done through a small one-inch incision and takes about an hour. SI joint treatment using the patented triangular design of the iFuse implant has been clinically evaluated more than any other SI joint fusion procedure.
10 Common Misconceptions About SI Joint Pain
Frequently Asked Questions About SI Joint Pain
The SI joint, short for sacroiliac joint, is located in the pelvis, connecting the iliac bones (pelvis) to the sacrum (lowest part of the spine above the tailbone).
SI joint pain can be caused by degeneration or injury to the supporting ligaments, similar to other joints in the body.
Yes, SI joint pain can often be misdiagnosed as lower back pain, as the symptoms may overlap. Proper diagnosis is crucial to determine the actual source of pain.
Women tend to have more flexible sacroiliac ligaments than men, which allows for mobility during childbirth. However, both men and women can experience SI joint pain.
In many cases, SI joint pain can be relieved through non-surgical treatments such as medications, physical therapy, external support (SI joint belts), and therapeutic injections.
Studies suggest that approximately 15-30% of chronic low back pain may be attributed to the SI joint. It is also prevalent in a significant percentage of post-lumbar fusion patients.
Yes, SI joint pain can cause radiating symptoms such as numbness, tingling, or weakness in the lower extremities due to its proximity to nerve roots.
Yes, SI joint pain can affect various daily activities, including walking, sitting for long periods, transitioning from sitting to standing, and engaging in physical activities.
SI joint fusion is a minimally invasive surgical option for chronic SI joint pain. However, other surgical procedures may be considered based on individual circumstances.
Yes, studies have shown positive long-term results with SI joint fusion using the iFuse Implant System, providing improved pain relief and increased function up to 5 years post-surgery.
