SI JOINT PAIN

Inflammation is the root cause of SI Joint pain. There are many reasons why inflammation develops in the SI joint, but hypermobility (loose joint) and hypomobility (stiff joint) are the main conditions responsible for the change that causes the development of pain in the first place.

But… What’s the si joint?

Simple. It is the joint located between the Sacrum and the Ilium bones of the pelvis on each side. Strong ligaments connect them, and their function is to support the upper body's weight.

Sacroiliitis

Sacroiliitis is an inflammation in the SI joint caused by abnormal motion in that area.

So, what are the causes of Sacroiliitis (AKA SI joint pain)?

SI joint pain is commonly caused by repetitive use. For example, continued pounding pressure from an exercise like running may be a cause. Other causes may include:

  • An injury or trauma to the ligaments that surround the SI joint

  • Previous spine surgery

  • Uneven leg length, asymmetry in pelvis structure

  • Childbirth

  • Infection

  • Inflammation

  • Ankylosing Spondylitis

IT’S IMPORTANT TO RECOGNIZE THE SYMPTOMS OF SI JOINT PAIN

  • Pain in the lower back, hips, or buttocks

  • Pain that radiates from the pelvis to the thighs, knees, or feet

  • Pain that worsens when standing up or sitting down (For instance, when getting in and out of the bed or vehicle)

  • Numbness or tingling in the legs

  • Weak legs

If you have been diagnosed with Sacroiliac Joint Dysfunction, you may be a candidate for Aurora’s SI Joint Fusion Systems. SiLO™ & SiLO TFX™

The SiLO™ allograft system was developed for the sacroiliac joint to reduce pain and stabilize it by immobilizing and fusing iliac and sacral elements in a short, minimally invasive procedure.

AND IT’S ONLY THE SIZE OF A PENNY!

SiLO TFX™

It’s another option for you!

A human pelvic bone with a spinal column, showing a medical implant with the logo 'SiLO TFX' in purple, attached to the pelvis. The implant reconstructs and stabilizes the sacroiliac joint.

Aurora Spine & Pain has developed a bridge cone with two screws specially designed for each part of the SI joint (the Sacrum and Ilium). The unique shape and design of the SiLO TFX™ assist in promoting bone growth, immobilizing the SI joint, and providing pain relief to the patient.

This version is made of Titanium alloy, a biocompatible material.
