Semi-rigid fixation, with better fatigue performance and imaging.
PEEK-OPTIMA Ultra-Reinforced is specially designed to provide the strength of metal with reduced stiffness. These characteristics make it ideal for applications such as intramedullary nails, where load sharing is desired. PEEK-OPTIMA Ultra-Reinforced fracture nails allow semi-rigid fixation, which can promote earlier healing and help avoid stress shielding and non-unions.
The extremely high fatigue strength of PEEK-OPTIMA Ultra-Reinforced is well documented. Dynamic ASTM F1264 testing demonstrated that PEEK-OPTIMA Ultra-Reinforced fracture nails offer more than an order of magnitude improvement in fatigue strength over similar Titanium nails. This means it has the potential to prevent device failures related to high cyclical loading — a major advantage over metals.
Another desirable characteristic of PEEK-OPTIMA polymers is that they are inherently biologically inert. This can reduce implant tissue adhesion to a greater degree than Titanium. The result: Nails made from PEEK-OPTIMA Ultra-Reinforced can simplify implant removal and conserve bone during revision surgeries.
Imaging is another area where PEEK-OPTIMA polymers offer a clear advantage. They are inherently radiolucent and provide clear, artifact-free imaging. This simplifies placement of intramedullary nails and monitoring the fracture site to assess healing and identify infections.
