What It Is
The Zespin SI Joint Fusion System is a medical device used to stabilize and fuse the sacroiliac joint in patients with degenerative sacroiliitis and joint dysfunction. It is intended for use in minimally invasive surgical procedures.
FDA-Cleared Indications
- Sacroiliac joint stabilization and fusion
- Treatment of degenerative sacroiliitis
- Treatment of sacroiliac joint dysfunction
Clinical Applications
- Minimally invasive sacroiliac joint fusion
- Stabilization of the sacroiliac joint in patients with symptomatic joint dysfunction
- Surgical treatment of degenerative sacroiliitis when conservative treatment has not provided adequate relief
Evidence Summary
The available literature includes 10 studies, comprising various study designs such as prospective and retrospective analyses, conducted between 2023 and 2025. These studies provide insights into the device's clinical performance and safety.
Reported Outcomes
Published studies report that the Zespin SI Joint Fusion System demonstrates promising clinical outcomes, including improved joint stability and pain reduction. The evidence suggests effective fusion rates and patient satisfaction with the procedure.
Safety Profile
Reported complications include potential neurovascular injury, although the risk is minimized with novel surgical approaches. Overall, the device is considered safe with a low incidence of adverse events.
Evidence Limitations
Current evidence is limited by the small sample sizes and short follow-up durations in some studies. Further research is needed to establish long-term outcomes and comparative effectiveness against other fusion systems.
Practical Considerations
- The system is intended for implantation in the sacroiliac joint and should be used according to the manufacturer’s surgical technique and FDA-cleared labeling.
- Available implant sizes, shapes and instruments depend on the specific system configuration; the operative team selects the implant based on patient anatomy and imaging.
- MRI safety and scan conditions must be confirmed from the current manufacturer’s labeling. Do not assume that an implanted device is MRI safe without this information.
- Contraindications and precautions may include active infection, inadequate bone quality, allergy or sensitivity to implant materials, and medical conditions that prevent safe surgery or fusion.
- The provided FDA record lists product code OUR and 510(k) K221050, but the supplied record does not include the complete FDA indications, materials or MRI labeling.
