Once the SI joint is confirmed as the cause of a patient's symptoms, treatment can begin. Some patients respond to physical therapy, chiropractic manipulations, use of oral medications, as well as injection therapy. Intermittent use of a pelvic belt may provide symptomatic relief as well. These treatments are performed repetitively, and frequently symptom improvement using these therapies is temporary. At this point, you and your patient may consider other options, including minimally invasive surgery.
SI Joint Fusion With The iFuse Implant System®
The iFuse is a minimally invasive surgical option, designed to be less invasive than traditional open surgical SI joint fusion. The iFuse Implant System is indicated for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis. The procedure typically involves three small titanium implants surgically inserted across the SI joint. It is designed to create a durable construct to stabilize the SI joint. The procedure is done through a small incision and takes about an hour.
With the iFuse Implant System, there is no need for: BMP in conjunction with autologous bone graft, additional pedicle screws and rods, hollow modular anchorage screws, cannulated compression screws, threaded cages within the joint, or facture fixation screws.
iFuse Potential Benefits:
- Less invasive than traditional open SI joint fusion surgery with no extensive soft tissue stripping
- Plus: minimal incision size (approximately 2-3 cm long) and minimal tendon irritation
- Straightforward minimally invasive surgical approach
- Designed for maximum joint stability
- Triangular implant profile minimizes rotation and an interference fit minimizes micromotion
- Rigid titanium constructs and large implant surface area provide stability
- Porous plasma spray coating allows for biological fixation
- Larger implant surface area designed to maximize post-surgical weight bearing capacity
- Biomechanically rigorous implant designed specifically to stabilize the heavily loaded SI joint
- The iFuse implant has 3X shear and 7X bending strength compared with screws1
- Pin, drill, broach, insert implants, and close
- Procedure takes about an hour
- Potential for less blood loss and reduced soft tissue stripping

Over 10,000 procedures have been performed with the iFuse Implant System.
SI-BONE is sponsoring two prospective clinical trials of iFuse for SI joint disorders.
The iFuse Implant System is intended for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis. As with all surgical procedures and permanent implants, there are risks and considerations associated with surgery and use of the iFuse Implant. Please review the iFuse Instructions For Use for a complete discussion of contraindications, warnings, precautions, and risks.
