Transfix & Compress the SI Joint with One Implant

The Liberty SI™ Fusion System is intended for sacroiliac (SI) joint fusion for conditions including SI joint disruptions and degenerative sacroiliitis. The procedure involves the lateral insertion of 1 or 2 titanium implants transfixing across the ilium and sacrum designed to apply a compressive force to stabilize and fuse the SI Joint. Liberty SI™ is single use and provided sterile.

Main Causes of SI Joint Dysfunction

  • Previous Spine Surgery: Up to 75% of patients undergoing lumbar fusion will develop SI joint degeneration within 5 years.*
  • Pregnancy: Hormone Relaxin can lead to hypermobility of SI joint*
  • Trauma: Trauma can cause disruption to SI joint which leads to chronic pain
  • Obesity: Obesity can cause excessive load to the SI joint leading to dysfunction*

    Features & Benefits of Liberty SI

    • Specifically designed to avoid the most common complication in SI fusion procedures, foraminal impingement
    • Available in multiple diameters & length offerings, composed of Titanium alloy with partial hydroxyapatite coating
    • Only Lateral SI System on the market that engages the cortical walls of the ilium and sacrum for true joint compression
    • Bone decortication during procedural steps helps promote joint fusion
    • Implant fixation, compression and fusion may reduce hypermobility of the SI Joint*
    • Single lateral surgical approach used with 1 implant (2nd implant optional) may reduce risk of Superior Gluteal Artery injury compared to multiple implant systems

      Research & Data

        • It is estimated that SI joint dysfunction is the underlying etiology for 15 to 30% of patients suffering from chronic low-back pain*
        • Randomized clinical trials support sacroiliac arthrodesis for treating SI joint dysfunction in carefully selected patients who previously failed conservative measures*
        • SI Joint arthrodesis has been shown to be an effective way of reducing pain, increasing* quality of life and reducing opioid use
        • Patients undergoing minimally invasive surgery report better pain relief compared with those receiving open surgery at 12 months postoperatively*
