7.0mm & 8.0mm Cannulated Fastener System

Dr. Michael Weaver, orthopedic surgeon, shares one of the major clinical advantages of our UnifiMI technology. Mechanical Integration (MI) is a less invasive method to instantly secure an implant to normal or compromised bone utilizing an integrated thread geometry.

UnifiMI Fastener System Highlights

  • Resists multi-planar and multi-directional loads through Mechanical Integration.
  • Designed to engage twice as much bone when loaded in any direction as compared to standard screws.
  • 24mm provides most ideal length for hip fractures1.

8.0mm Fastener Overview

The 8.0mm fastener uses the same 5.0mm drill bit as the 7.0mm fastener, while it provides 39% more mechanically integrated bone volume with only 7.9% more metal.

EXPERT INSIGHTS

Dr. Michael Weaver, orthopedic surgeon, provides a high-level overview of our 7.0mm & 8.0mm Cannulated Fastener System, featuring Unifi Mechanical Integration (UnifiMI). 

 

The UnifiMI 24mm thread length provides superior performance in osteoporotic bone. Dr. Weaver shares the research on why this is the ideal thread length.
