Inorganically Surface Modified Polymers for Orthopaedic and Spinal Implants

Detailed Technology Description

University researchers have developed surface-nanopatterned polymers for implant applications, in particular, PEEK materials modified to exhibit nanostructured surfaces that promote osseointegration. Surface modification is done by coating the polymer with biocompatible metals, alloys, and oxides that are nanostructured by various means. Whereas polymers integrate poorly with bone, the invention’s nanostructured coating enhances cell adhesion and promotes preferential stem cell differentiation to bone cells. The invention thus enables use of elastically bone-like and x-ray translucent PEEK for knee prostheses and other joint replacements or bone-anchored implants, e.g., hip and shoulder replacements and dental implants.
