SI Joint Fusion with the iFuse Implant System®
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. There are potential risks associated with the iFuse Implant System. It may not be appropriate for all patients and all patients may not benefit.

Sacroiliac (SI) joint fusion is a surgical procedure performed in an operating room, with either general or spinal anesthesia. You will be lying down during the surgery while your surgeon uses a specially designed system to guide the instruments that prepare the bone and insert the implants. Both the surgical technique and the iFuse Implant System are designed to offer the maximum protection to your surrounding tissues.
The entire procedure is performed through a small incision (approximately 2-3cm long), along the side of your buttock. During the procedure, fluoroscopy provides your surgeon with live imaging during the procedure to facilitate proper placement of the implants. Fluoroscopy is an imaging technique commonly used by physicians to obtain real-time moving images of internal structures using X-rays. Normally three implants will be used, depending on your size.
The procedure takes approximately an hour. Your surgeon will decide when you can return home based on your postsurgical status.
Following the Surgery
At discharge, your surgeon will arrange follow-up visits to assess your progress, health status (including the status of your incision) and may take additional images of your surgical site. Your doctor will advise you when it is appropriate to resume your daily activities and weight bearing. Return to work will depend on your postsurgical progress and occupation.
Possible benefits of an MIS procedure may include:
