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.
MC+ Static Axial Compression Average Maximum Load 7511 N Standard Deviation 633 N Range 6609 – 8154 N MC+ Dynamic Compression Test Frequency 5 Hz Load Cycle 200 – 2000 N Number of Cycles 5,000,000 (without cracking or deformation) MC+ Dynamic Torsion Test Frequency 5 Hz Moment Load Cycle +/- 1000 N-mm Number of Cycles 5,000,000 (without cracking or deformation) Independent testing of ROI and MC+ implants was completed by Orthopaedic Research Laboratories, CRITT-MDTS and LNE.
