SI Joint Pain

What is SI Joint Pain?

The sacroiliac (SI) joint is located in the pelvis, connecting the sacrum (the area right above the tailbone and the lowest part of the spine) and the iliac (pelvic) bones. If you place your hand on your lower back, you should be able to feel both sides of your SI joint. The two joints work together to provide support and stability whenever you are walking, lifting, and more.

As with any other major joint in the body, the SI joint can become injured or worn down over time. Whether you have suffered an injury, or the SI joint has begun to degenerate for another reason, SI joint pain is often felt in the lower back and buttocks, but it can also cause pain or discomfort in the hips and higher up the spine.

SI joint pain can resemble other conditions such as a herniated disc or hip problems. As we age, the cartilage between the bones wears down, causing the bones to rub together and leading to pain. The SI joint is a synovial joint that is filled with fluid, and it also has free nerve endings, often leading to chronic pain if the joint deteriorates.

This pain can range from mild to severe, depending on the extent of the deterioration and cause. For those who have acute SI joint pain, they will experience the pain for just a few days to several weeks before it heals. However, there are those who suffer from chronic SI joint pain which lasts for more than three months, feeling constant and debilitating.


The pain begins in the lower back and buttocks, but it may travel to the lower hips, groin, and the upper thigh. It can even travel to further up the spine as well. Patients usually experience pain on just one side of their body, but it can occur on both sides.

The symptoms can worsen whenever you sit, stand, sleep, walk, run, or do something physical. The pain varies depending on the cause and severity of the condition.


SI joint pain can occur following a number of instances. The pain begins once the ligaments become too loose or too tight. A fall, work injury, car accident, childbirth, or hip or spine surgeries can all lead to SI joint pain.

Uneven movement on either side of the pelvis can also cause SI joint pain. This uneven moment happens when one leg is longer or weaker than the other, or if there is arthritis in the hip. Because SI joint pain resembles other conditions, it is important to see a specialist to properly diagnose and treat the condition.

iFuse Implant System

The iFuse Implant System is one of the most innovative to date. Manufactured by SI-BONE, this minimally-invasive treatment method is ideal for patients living with chronic low back pain caused by the sacroiliac (SI) joint.

The SI joint is often the culprit of lower back pain, something that 80 percent of the population will experience at one time or another. It is estimated that SI joint disorders affect 15-30 percent of chronic low back pain patients and can be blamed for more than 40 percent of new low back pain cases.

As you can see, the SI joint can be quite problematic and cause serious problems for patients of all ages and medical histories. Thanks to the iFuse Implant System, patients suffering from SI joint pain finally have an effective treatment option that isn’t surgery.

What Is the iFuse Implant System?

First introduced in 2009 by SI-BONE, the iFuse Implant System has helped thousands of patients looking for an alternative to surgery. The implant is a triangular device that was developed to stabilize and merge the SI joint. One of the main causes of SI pain is a weakened SI joint, which can make it feel like your low back is giving out at times. The implant will help relieve the strain and pressure put on the SI joint by acting as a replacement for the worn-down cartilage.

With the iFuse implant, patients experience improved function, and many have reported their pain has diminished completely.

What Are the Benefits of the iFuse Implant System?

One of the major benefits of the iFuse Implant System is that it is a minimally-invasive, non-surgical treatment option for widespread low back pain caused by SI joint dysfunction. At Texas Partners Healthcare Group, we strive to provide our patients with options that treat the root of the problem, rather than masking it with prescription medications.

While surgery is often necessary for patients with back pain, there are numerous nonsurgical options out there today, including regenerative medicine, stem cell therapy, and implant systems like the iFuse.

Some of the other benefits of the iFuse Implant System include:

  • Minimally-invasive procedure performed through a small (one to two inch) incision
  • Shape of the implant device encourages joint mobility
  • The shape, material, and intention of the implant are excellent for stabilization of the SI joint

This treatment option is ideal for patients with SI joint conditions such as degenerative sacroiliitis and sacroiliac joint disruption.
