Symptoms of SI joint dysfunction include:

• Pain in your buttock
  Pain on one or both sides of your lower back that may extend into the thigh or groin.
• Difficulty sitting or lying on the painful side
  These positions can stress the SI joint, which may cause pain and make simple actions like turning over in bed difficult.
• Pain performing daily activities
  Climbing stairs, kneeling or other activities that cause your pelvis to twist can cause pain.

If you have some of these symptoms, your doctor can perform simple tests to determine whether your pain is caused by an SI joint problem.

Because of its pivotal location, a damaged SI joint can make the simplest activities painful.

1. Lumbar spine
2. Sacrum
3. Ilium
4. Sacroiliac Joint

Minimally invasive surgery using the SImmetry system typically takes less than one hour to perform, has fewer postoperative complications than open SI joint fusion surgery and involves:

• < 50cc estimated blood loss¹
• A small incision—typically only a couple centimeters—on one side of the buttock²
• Brief hospital stay³
• Potential for short weight-bearing recovery period based on sacroiliac joint fusion postoperative guidelines⁴
• True SI joint arthrodesis⁵

The SImmetry system affords an efficient and effective minimally invasive technique to effect a true arthrodesis of the sacroiliac joint as follows:

• Minimally invasive lateral access for safety and control
• Joint preparation with the proprietary SImmetry Decorticator^® instrument removes cartilage and decorticates opposing joint surfaces
• Bone graft delivery to the prepared joint to facilitate fusion
• Joint fixation with threaded titanium implants
