Biocompatibility of PEEK Polymers

This presentation reviews multiple aspects of the biocompatibility of PEEK.



Porous PEEK and Surface Modified PEEK for Musculskeletal Applications

Polyetheretherketone is the thermoplastic of choice for orthopaedic devices due to biocompatibility and strength. Despite PEEK’s widespread clinical use, two limitations include lack of a commercially viable scaffold for osteointegration and relative poor affinity to bone. The purpose of this work was to develop a reliable means to manufacture porous PEEK and to covalently bond a polymer coating for improved bone cell response for porous and solid devices.



Novel Mthod for Making Homogeneous Bioactive PEEK Compounds using an ultrsonic Co-feeding and On-line Mixing System

In this work, the feasibility of an ultrasonic co-feeding system was demonstrated by preparing homogeneous mixtures from two materials with different physical properties. Meanwhile, a homogenous mixing of commercially used implant grade polyetheretherketone polymer (PEEK) and bioglass which are prone to segregate during traditional stir mixing was proved for further bioactive compound fabrication.



Clincal Trials of the MITCH Cup

This presentation details the first clinical trials of the MITCH Cup used in total hip arthroplasty.



A Novel, Flexible PEEK Implant for Treatment of Vertebral Compression Fractures: From Concept to Clinic

Treatment of VCFs using a structural implant consisting of PEEK represents a potentially viable alternative which addresses limitations of vertebroplasty and balloon kyphoplasty. We have developed a minimally invasive, radiopaque, flexible PEEK implant known as Kiva, which is designed to stabilize the fractured vertebra, reduce volume of bone cement, improve its containment, provides a mechanism for height restoration, and offers the structural support necessary for bioactive injectables. This effort describes the engineering and clinical validation to bring the design from concept to market.
