Who is Not a Candidate for the Rialto SI Fusion System?

The Rialto SI fusion system should not be used in patients with the following conditions:

  • Deformities
  • Tumor resection
  • Infection near the operative site and/or signs of local inflammation
  • Failed previous fusion
  • Suspected or documented allergy or intolerance to the component materials


Potential risks in any surgical procedure include unforeseeable complications caused by anesthesia, blood clots, undiagnosed medical problems, such as silent heart disease, and rare allergic reactions.

In addition, some risks of SI joint surgery include incomplete pain relief, damage to the nerve roots, infection, and complications with the hardware.

Most of these complications can be treated once they are detected, but sometimes they require a longer period of hospitalization or recovery, additional medications, and sometimes even additional surgery.

These risks will be explained by the primary surgeon. In general, these complications happen very infrequently, but it is important to remember that surgery is a difficult process, and, therefore, unforeseeable complications do occur.
