Overview – 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. The SI joint is designed to absorb shock forces and is naturally constrained to only limited movement. Instability in the SI joint is a major pain generator in some
patients.
Preparation – To begin, you are given medicine to put you to sleep and block sensation in your SI Joint. You’re positioned face down and two small incisions are made in the skin. With the help of fluoroscopy two small guide pins
are placed within the SI Joint. These guide the approach for the remainder of the procedure.
Procedure – The CornerLocTM SI Joint Fusion System has been specifically designed to achieve optimal stabilization and fusion potential, with the least invasive approach and surgical instrumentation available. After careful preparation
of the SI Joint, two CornerLocTM grafts are placed orthogonally within the SI Joint, effectively creating immediate joint stability and an ideal environment for fusion. The CornerLoc cortical allografts have been painstakingly engineered
to provide maximum stabilization, transfixing the SI joint with minimal risk of post-operative complications.
Post procedure – Once the procedure is complete you will be monitored for a couple of hours and should be able to go home. Once at home your physician will provide instructions to aid in your recovery.
