The SI Joint Fusion Experts

The sacroiliac (SI) joint is located in the pelvis; it links the iliac bones (pelvis) to the sacrum (lowest part of the spine above the tailbone). It is an essential component for energy transfer between the legs and the torso.

Physicians Who Perform SI Joint Fusion

North American Spine partner physicians are board-certified, minimally invasive specialists in SI Joint Fusion and other related procedures. They are among the best in the field, and many have served as teachers of the next generation of minimally invasive specialists.


Unlike at most practices, North American Spine partner physicians may collaborate on a complex procedure to ensure that all the required skill and knowledge is brought to the case. But perhaps the most telling fact of all is this: 97% of patients say they would recommend their doctor to a friend.



Let’s Get Started

Answering a few questions will kickstart the process. Let's get you free of pain.

Benefits of the SI Joint Fusion

The minimally invasive procedure is designed to stabilize and fuse the SI joint. Clinical studies have demonstrated that the SI Joint Fusion procedure has improved pain, patient function, and quality of life.


Other benefits include:

  • Triangular implant profile minimizes rotation and an interference fit minimizes micromotion
  • Porous surface promotes bony ongrowth and ingrowth
  • Designed specifically to stabilize and fuse the heavily loaded SI joint
  • Advanced instrumentation provides immediate stabilization

Compared to traditional, “open” surgeries, the minimally invasive approach used by North American Spine physicians results in less surgical trauma, less bone and tissue damage, and results in fewer complications and a reduced recovery period. Note: we do see patients whose previous spine surgeries are no longer providing them the relief they need.

Details of the SI Joint Fusion

For an SI Joint Fusion, the surgeon uses a specially designed system to guide instruments that prepare the bone and insert specialized hardware. Normally three implants will be used, depending on the patient’s size.


The surgical technique is designed to offer the maximum protection to your surrounding tissues. The hour-long procedure is performed through a small incision (approximately 2-3cm long), along the side of your buttock. Real-time moving images of internal structures using X-rays ensure proper placement of the implants.

Preparing for the SI Joint Fusion


Before pursuing an SI Joint Fusion minimally invasive procedure, prospective patients should have tried conservative methods, such as physical therapy, chiropractic, and spinal injections. If those methods have not produced meaningful relief, you may be a candidate for a North American Spine procedure.

SI Joint Fusion Recovery

Usually, patients will be walking the same day as the procedure, and most doctors tell patients that they can return to work and perform light activities after 2 weeks. More in-depth, customized recovery guidelines will be provided by your North American Spine physician. The vast majority of patients report a significant and lasting reduction-or the complete eradication-of their pre-op pain.


While every surgery carries some risk of injury or infection, complications and adverse events are rare. Your physician will counsel you on these risks prior to the procedure.
