MC+® Reliability
Independent testing completed by several laboratories, including
Orthopaedic Research Laboratories, confirms the reliability of the ROI & MC+ implants
as intervertebral body replacement devices.
Mechanical testing
Testing of the ROI and MC+® implants was completed by
independent laboratories in accordance with ASTM F 2077
(Test Methods for Intervertebral Body Fusion Devices).
This testing confirms that the ROI and MC+ provide the
necessary mechanical properties to provide primary
stability and distribution of loads along the spine
segment. These mechanical properties and design of the
implants provide conditions necessary for fusion.
