CornerLoc™ SI Joint Stabilization System

The sacroiliac joints (SI) are the foundation of the spine, located at the junctions of the sacrum and ilium on each side. These complex joints, composed of systems of ligaments and multiplanar joint surfaces, transmit the forces exerted through the spine from the upper body to the legs.

Causes of SI Joint Instability and Pain

  • Prior injury or accident
  • Postpartum pelvic girdle pain
  • Ligamentous loosening due to pregnancy
  • Arthritis
  • Osteoarthritis
  • Low back instability or prior low back surgery

Common Symptoms of Sacroiliac Joint Dysfunction

As with other joints in the body, the SI joint can become damaged, can suffer from wear and tear, or the ligaments supporting the joint may be stretched or injured. Sacroiliac joint dysfunction and the associated pain can be caused by a specific traumatic event (disruption) or can develop over time (degeneration).

  • Low back pain
  • Pelvis/buttock pain
  • Lower extremity pain
  • Hip/groin pain
  • Problems sitting, sleeping, or walking

The CornerLoc™ SI Joint Stabilization System may be the right solution for you. This system has been specifically designed to achieve optimal stabilization and fusion potential, with minimal surgical invasiveness. After careful preparation of the SI joint, two CornerLoc™  grafts are placed orthogonally within the SI joint, effectively creating immediate joint stability and an ideal environment for fusion.
