Solvay partners with Carbon22™ to develop Creed™ cannulated screws for orthopaedics

Solvay's Zeniva® polyetheretherketone (PEEK) resin has been selected by Carbon22™, a GLW company, for its new Creed™ cannulated screw combination for foot and ankle surgery
.
This advanced new screw combination recently received 510(k) clearance from the U.
S.
Food and Drug Administration (FDA)
.

To make this new combined transparent plastic-metal hybrid composite, Solvay's implant-grade radioactive transparent Zeniva® PEEK resin was coated on a titanium core prior to final processing
.
This high-performance material solution allows the screw to be seen by X-ray or computed tomography (CT), while enabling surgeons to accurately assess anatomical details near and behind the implant site without visual distortion or artefacts
.

The new Creed™ cannulated screws are produced using Carbon22™'s unique manufacturing technology
.
This breakthrough process helps control costs by reducing material waste compared to conventional titanium screws, which generate a lot of expensive scrap during machining
.
Additionally, Carbon22™ Hybrid Technology enables a more aggressive cutting tip that is not possible with an all PEEK screw design
.

Anna Maria Bertasa, Healthcare Global Marketing Manager, Solvay Specialty Polymers, said: "We worked closely with Carbon22™ to achieve strong adhesion to titanium, which is not inherent to PEEK
.
Solvay's broad and deep technology Expertise and advanced materials technology sets us apart from the competition and allows us to help create innovative Creed™ systems
.
We welcome new challenges and address the unique individual needs of our customers to give them a competitive advantage and help them succeed"
.

While all-titanium screws are opaque to X-rays and the imaging of all-PEEK screws is affected by their diameter, the Creed™ Hybrid Composite Screw allows X-rays to pass through the bone
.
The contours produced by these new screws greatly enhance the visualization of bony structures
.
Surgeons can use this ability to confirm screw placement during surgery, check positioning post-operatively, and determine the status of the healing process at follow-up
.
The ability to image screw locations gives surgeons more confidence and can help them achieve better outcomes
.

"Solvay is a recognized industry leader in implantable PEEK materials," said Vadim Gurevich, CEO of Carbon22
.
"Their team provided exceptional materials expertise and engineering capabilities that were instrumental in the development of our new Creed system
.
Together, we are actively involved in new developments that are expected to further advance the next generation of orthopedic devices
