7.0mm & 8.0mm

Cannulated Fastener System

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 fractures*.​

7.0mm Fasteners Offered in Multiple Thread Lengths.

System Overview

The OsteoCentric Trauma Cannulated Fasteners consist of cannulated fasteners in a variety of lengths and diameters to accommodate different procedures and patient sizes. The fasteners are provided non-sterile and are manufactured from Stainless Steel per ASTM F138.

The OsteoCentric Trauma Cannulated Fasteners System includes:

7.0mm Cannulated Fasteners:

  • Full Thread, 24mm Partially Threaded, and Variable Threaded options 

  • 60 – 180mm lengths in 5mm increments 

 

8.0mm Cannulated Fasteners:

  • Partially Thread (24mm) option

  • 60 – 130mm lengths in 5mm increments

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) and discusses the clinical relevance of a 16mm washer.

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