The Sacroiliac (SI) joint connects the sacrum to the left and right hip bones. The SI joint is located at the bottom of your spine, which is the reason why most people confuse SI joint pain with lumbar pain. The purpose of the SI joint is to stabilize the spine and allow it to remain strong and upright when standing, running or walking.
The goal of a minimally invasive SI joint fusion procedure is to decompress the nerve that is affected in the lower area of the spine and then immediately stabilize the spine to help patients return to their normal daily activities.
The surgeon will enter the SI joint through a small incision in the back. Through this incision the surgeon will fuse together the sacrum and the pelvis to stabilize the spine and decompress the affected nerve.
