The CornerLoc™ Procedure Is Used To Treat SI Joint Pain

The CornerLoc™ SI Joint Stabilization 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.

The cortical allografts have been painstakingly engineered to provide maximum stabilization, transfixing the SI joint with minimal risk of post-operative complications.


Minimally Invasive – CornerLoc™ is a posterior approach procedure. It is done via two small incisions in the lower back, which is the shortest and safest route to the SI Joint.

Fast Recovery – With CornerLoc™ the risk of neural and post-operative complications are extremely low. The unique graft design creates immediate stability within the SI joint.

Significant Pain Relief – CornerLoc™ retrospective data, which is summarized on their News & Events page, is showing excellent SI joint pain reduction and improvement in daily patient function.
