Years of Clinical Use & Success
Traditional Implants Damage Bone During Insertion
Establishing a stable implant-to-bone connection and protecting the bone surrounding the implant is critical. Traditional methods often damage this surrounding bone during surgery, making it weaker and less able to support the implant. This can slow the recovery process, potentially increase complications, and create uneven stress on both the implant and bone over time.

Introducing MIS Bone Preservation Technology
UnifiMI MIS Bone Preservation Technology preserves the bone structure, creates a stable foundation and is designed to accelerate the patient’s healing journey.
Mechanical Integration Technology
Unique thread geometry instantly and circumferentially interlocks with bone by entrapping and containing bone between the thread form.
Mechanical Integration creates a structural and functional connection between an implant and bone which transfers and shares loads in a similar manner to biological integration (Osseointegration).
UnifiMI is supported by 10 years of advanced research and development. No other SI Joint System on the market is equipped with advanced UnifiMI technology.
Patented MIS Bone Preservation Interface
JOINT PREP & DECORTICATION
Decortication has been shown to promote the fusion process by exposing subcortical blood and marrow, encouraging vascularization, osteogenic and inflammatory factors to promote the bone growth necessary to achieve fusion.

BIOMECHANICAL PERFORMANCE
Compression, Peak Stripping Torque, & Off-Axis Resistance
Integrity Fasteners with UnifiMI technology exhibited superior biomechanical performance vs. Legacy standard thread designs

Higher peak stripping - allows for more stabilization without losing implant purchase in the bone
Higher resistance to off-axis loading. UnifiMI’s unique interface resists the forces that the body imparts on the implant that can cause loosening or failure much better than other implants
Greater pull-out force than the market leading implant option - leading to stronger stabilization of the joint
51%
More than the maximum compression force generated by leading market implants - this allows the surgeons to compress and stabilize the joint more effectively, which are proven factors in generating fusion
SYSTEM
The Integrity-SI System is clinically proven to reduce post-operative pain, facilitate bony arthrodesis and improve patient outcomes during primary or revision sacroiliac joint fusion procedures.
