Why Choose iFuse?
About SI Joint Fusion using the iFuse Implant System®
Sacroiliac joint fusion is a surgical procedure intended to stabilize the joint and eliminate motion. The iFuse Implant System® is intended for sacroiliac fusion for conditions including sacroiliac joint dysfunction that is a direct result of sacroiliac joint disruption and degenerative sacroiliitis. This includes conditions whose symptoms began during pregnancy or in the peripartum period and have persisted postpartum for more than 6 months. This system uses small titanium implants placed across the sacroiliac joint to stabilize and fuse it. (Figures 2,3) SI joint treatment using the patented triangular design of the iFuse Implant™ has produced unparalleled clinical results. More than thirty published, peer-reviewed articles demonstrate safety and effectiveness of the iFuse Implant.* The iFuse Implant is the only SI joint fusion device with multiple clinical studies demonstrating that treatment improved pain, patient function, and quality of life.**
Traditional sacroiliac joint fusion involves open surgery that may take several hours. Open surgery typically involves a large incision to access the SI joint, bone removal, and adding bone graft to help the joint heal. Open surgery usually translates into several days of hospitalization. The potential advantages of the SI-BONE iFuse Implant System include:
- Minimally invasive surgical (MIS) approach
- Patented, 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
- Rigid titanium construction and implant geometry provide immediate stabilization
About the Procedure
SI joint fusion using iFuse is performed in an operating room under general or spinal anesthesia. Your doctor uses a specially designed system to guide the instruments that prepare the bone and insert the iFuse Implants. The surgical technique and the iFuse Implant System are designed to offer the maximum protection to your surrounding tissues and minimize soft tissue damage.
The entire procedure is performed through a small incision (2-3cm) made along the side of your buttock. During the procedure fluoroscopy (real time X-ray) provides your doctor visual feedback to enable proper placement of the implants. The number of implants used depends upon your size and the anatomy of your ilium and sacrum.
Post-operative X-ray shows SI joint with the iFuse Implants
The procedure typically takes about an hour. Your doctor will make the decision for how long you remain in the hospital based on your post-surgical status.
