Committed to Ongoing Education- Sacroiliac Joint Fusion


To complement the 20 plus types of neurosurgery procedures in Doctor Adam Lewis’ repertoire, he recently completed training in the sacroiliac (SI) joint fusion/iFuse course. This cutting-edge technique is a minimally invasive fusion technique for the sacroiliac joint.

  • What is the sacroiliac joint? – The sacroiliac joint transfers weight between the upper body and the legs and is stabilized by a network of ligaments and muscles. Though healthy ligaments and muscles limit motion, a normal sacroiliac joint allows a small amount of normal motion in any direction.
  • Where is the sacroiliac joint? – The sacroiliac joint is located in the pelvis and links the pelvis to the lowest area of the spine above the tailbone, the sacrum. 
  • Why is the sacroiliac joint important? – The sacroiliac joint absorbs the shock of walking, running and other activities from reaching the spine. Like all other joints, the sacroiliac joint can develop arthritis, and its support ligaments can become loosened or injured.

When arthritis is present or injury to the ligaments occurs, an individual can experience pain in the low back. Pain is especially present when one engages in activities such as lifting, running, and walking.

·  Do treatment options for sacroiliac joint pain exist? – Doctor Adam Lewis says physical therapy, chiropractic care, injection therapy, or the use of a pelvic belt may provide relief from painful symptoms. Unfortunately, because these treatments are performed on a frequent and regular basis, symptom improvement is temporary. If non-surgical treatment options do not provide relief, a neurosurgeon can discuss other options, including surgery.

Doctor Adam Lewis: The Benefits of SI Joint Fusion/iFuse

It is not uncommon for pain from the SI Joint to mimic disc or low back pain. To avoid unnecessary lumbar spine surgery, it is important to consider sacroiliac joint disorders when properly diagnosing low back pain.

Sacroiliac (SI) Joint Fusion with the iFuse Implant System®

Sacroiliac (SI) joint fusion with the iFuse Implant System is indicated for patients with conditions such as sacroiliac joint disruptions or degenerative sacroiliitis.

Sacroiliac (SI) joint fusion is a surgical procedure performed in an operating room. The patient receives general or spinal anesthesia and lies on his or stomach. The neurosurgeon uses a specially designed system to guide the instruments that prepare the bone and insert the implants. The entire procedure is performed through a small incision (approximately 2-3cm long), along the side of the buttock. Normally three implants are used, depending on the size. Doctor Lewis uses the surgical technique and the iFuse Implant System to ensure maximum protection to a patient’s surrounding tissues. The procedure takes about an hour.

The surgeon will send patients home depending on each person’s unique postsurgical status, and some patients have returned home two to three days following surgery.

Doctor Adam Lewis is committed to making sure every patient has a positive experience. Considering surgery is overwhelming, but selecting a good neurosurgeon like Adam Lewis can help alleviate the stress of a medical decision. By choosing Doctor Adam Lewis for your surgery, you can have a successful surgery and begin on the road to recovery!
