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
What's Inside
Variable Thread Tray, fasteners available in 70-180mm lengths at 5mm increments.
Fully Threaded Tray, fasteners available in 70-180mm lengths at 5mm increments.
24mm Thread Length Tray, fasteners available in 70-180mm lengths at 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.
24mm Thread Length Tray, fasteners available in 60-130mm lengths at 5mm increments.

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.
