What is the sacroiliac (SI) joint?

There are many structures in the lower back and pelvic area that can cause pain. Most commonly, people think of a “slipped or ruptured disc” as the most common cause of low back pain.

There is no need to suffer with low back, hip or leg pain any longer. Your pathway to relief and a return to normal activity begins with a simple phone call and expert evaluation

Our Treatment Approach

In the past, sacroiliac joint fusion involved several hours of open surgery involving a significant incision to access the joint, removal of cortical tissue from the joint and the use of bone grafts from other parts of your body to help fuse the joint. Patients typically required several days in the hospital after surgery and an extended recovery period at home.

Now, there is an alternative. A minimally invasive surgical procedure called the iFuse Implant System® is being performed with smaller incisions, less down time and greater long-term success.

This highly advanced procedure uses a guide pin to place the titanium implants across the sacroiliac joint. These small implants are designed to correct the sacroiliac (SI) joint by
allowing the surgeon to stabilize the joint without a long and involved surgical procedure.

Dr. Douglas Won, a pioneer in the advancement of minimally invasive surgery, is presently the only surgeon in the area with the extensive training required to perform the iFuse Implant procedure to correct issues of the SI joint. The surgery is performed in an out-patient setting at the new Star Medical Center, an innovative new specialized surgery center developed by Lumin Health.
