SImpact® Tri-Fin
The SImpact Sacroiliac Joint Fixation System consists of cannulated implants offered in various lengths, and threaded congurations to accommodate variations in patient anatomy. It is intended for sacroiliac joint fusion for conditions including degenerative sacroiliitis and sacroiliac joint disruptions.
- Self-harvesting screw design to pack bone material into fenestrations, enhancing fusion potential
- Anti-Rotational sleeve to prevent screw back-out
- Threaded configurations offer construct customization based on patients’ needs
- Surface architecture provides osteophylic titanium substrate1
- Promotes mineralization (bony on-growth) of implant2
