Regenerative Medicine

The CornerLoc™ SI Joint Stabilization System is designed to achieve optimal stabilization and fusion, 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 meticulously engineered to provide maximum stabilization, transfixing the SI joint with minimal risk of post-operative complications. 


  • Minimally Invasive – The CornerLoc™ procedure takes a posterior approach, creating two small incisions in the lower back, 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 – 8 out of 10 patients who undergo the CornerLoc™procedure report excellent pain relief and functional improvement with no serious complications. 

At the Pain Institute of Long Island, our pain management experts use the latest evidence-backed techniques to provide long-lasting pain relief for our patients. Please call 631-474-0707 or email us today to schedule your initial consultation.
