Comparison for the Mechanical Properties of Sternal Cerclage Implants
Test results showing the biomechanical superiority of Ortholox® UHMWPE Sternal Cerclage Bands have been published.
This study aims to determine the mechanical properties of the Ortholox® UHMWPE Sternal Cerclage Band System in a clinically significant test setup. In addition, these results compared with Polymer Cable, Steel cable and No. 5-0 (1.0mm Diameter) stainless steel wire.
Ortholox® UHMWPE Cerclage Band System was found to be 141% times stronger and 1.5 times more rigid when compared to its closest alternative, the polymer cable. While the polymer cable was displaced by 2.45mm at ~1.100N(the yield strength), Ortholox® UHMWPE Sternum Band reached this value at ~1.625N. Because sneezing has been shown to generate 814 Newtons of lateral distraction force on the sternum [Adams 2014], Ortholox® UHMWPE Sternal Cerclage Band System offers a safe alternative to Dual Polymer cable and metal implants (steel multifilament cable and steel wire) for sternal closure
