Zeniva PEEK is being used by Carbon22 for the company’s new cannulated screws for foot and ankle surgery.

Solvay says that its Zeniva polyether ether ketone (PEEK) resin has been chosen to help make composite screws for foot and ankle surgery.

The resin was selected by Carbon22, part of medical equipment company GLW for its new Creed cannulated screw system which recently received 510(k) clearance from the US Food and Drug Administration (FDA).

 The screws are made of a ortholucent, plastic-metal hybrid composite with Solvay’s implant-grade radiolucent Zeniva PEEK resin overmolded onto a titanium core prior to final processing. This material allows the screw to be seen with X-ray or computed tomography (CT) scanning while enabling the surgeon to assess anatomical details near and behind the implant site without visual distortion or artifacts, according to the company.

‘We worked closely with Carbon22 to achieve strong adhesion to titanium, which is not an inherent property of PEEK,’ said Anna Maria Bertasa, healthcare manager at Solvay.
