Increasing Adoption of PEEK-based Devices for Hand and Foot Applications
Both unfilled PEEK and carbon fiber reinforced PEEK materials have been successfully used in plating applications for the hand and foot.
Demonstrated benefits include:
PEEK-based intramedullary devices can provide similar advantages as metallic designs with potential additional benefits:
