Sternal closure bone cerclage wiring Ortholox® UHMWPE

multifilament polymer

The Ortholox® UHMWPE Sternotomy Closure System provides a fast and reliable solution for closing the sternum after open heart surgery or lobectomy. The Ortholox® UHMWPE Sternal Cerclage Band System is a band system woven from UHMWPE fibres that is quickly and easily applied with simple instrumentation and secures the sternum in a transverse, Figure-U and/or 8 shape with a patented locking block. This dynamic compression procedure allows for controlled expansion of the rib cage, providing secure stability. After surgery, it acts as a shock absorber by absorbing the loads caused by the patient's sneezing, coughing or daily movements. When emergency intervention is required, it can be easily removed with a scalpel on the operating table without the need for sterile wire cutting scissors or plate removal tools. Ortholox® UHMWPE Sternotomy Closure System is manufactured from Medical Degree Ultra High Molecular Weight Polyethylene material. For Ortholox® UHMWPE Sternotomy Closure System, very thin fibers are woven in the form of bands with a width of 5 mm to form a multifilament material. Sharp and blunt tip atraumatic needle options are available. By means of its wide cross section, it eliminates single-point stress. Pressure on bone tissue is distributed and thus decreased thanks to the wide surface of the band. By means of its wide surface, it is more reliable in osteoporotic bones when compared to sternal cables or cerclage wires. Three bands, each with a single winding, were measured to have a load carrying capacity of 2647 N. (Approx. 270Kg) The highest load calculated during a cough is 800-1000N and the bands have more than enough resistance to meet this load.
