Noteworthy in 2016: Material Model for PEEK under High Temperature Processing Conditions

Researchers have developed a modified Johnson-Cook (JC) model to describe the flow behaviour of polyether-ether-ketone (PEEK) with the consideration of coupled effects of strain, strain rate and temperature. As compared to traditional JC model, the modified one has better ability to predict the flow behaviour at elevated temperature conditions that are encountered during polymer processing. In particular, the yield stress was found to be inversely proportional to temperature from the predictions of the proposed model.

Noteworthy in 2015: Clinical Performance of PEEK Humeral Plates

Carbon fiber-reinforced-poly-ether-ether-ketone (CFR-PEEK) plates have recently been introduced as an alternative to traditional metallic plates. In a multicenter study involving the Orthopedic Services of 6 Italian hospitals, 182 patients with a proximal humeral fracture were treated with a CFR-PEEK plate. CFR-PEEK plates proved as reliable as metallic plates in the treatment of proximal humeral fractures. The advantages of these new devices include a better visualization of fracture reduction during intraoperative fluoroscopic assessment and easy hardware removal due to the absence of screw-plate cold fusion.

Noteworthy in 2015: PEEK for Orthodontic Wires

Most orthodontic equipment is fabricated from alloys such as stainless steel, Co-Cr and Ni-Ti because of their excellent elastic properties. In recent years, increasing esthetic demands, metal allergy and interference of metals with magnetic resonance imaging have driven the development of non-metallic orthodontic materials. In this study, researchers assessed the feasibility of using PEEK as orthodontic wires. Because of its properties and recent developments in coloration of PEEK, researchers concluded that the material is a suitable candidate for use as an esthetic metal-free orthodontic wire.

Conference Transactions and Final Program Archive: 2nd International PEEK Meeting, Washington DC

The Implant Research Center of Drexel University and Exponent, Inc., are pleased to archive the conference transactions on this website, including conference abstracts, as well as the final program for the 2nd PEEK International Meeting, which was convened at the Cosmos Club, Washington DC, USA, on Thursday and Friday, April 23 and 24, 2015. The purpose of the meeting was to bring together engineers, scientists, regulators, and clinicians from academia, industry, and government agencies and present leading edge research on advancements in medical grade PEEK technology and clinical applications.

 

Conference organizers are planning a CORR Symposium on Advances in PEEK Biomaterials based on papers and posters from the conference. Please contact Steve Kurtz (skurtz@exponent.com) for more details or if you are interested in contributing.



Noteworthy in 2014: Patient-Specific PEEK Implants for Cranioplasty

There is increasing use of PEEK implants for calvarial defects which remain a significant reconstructive challenge.This single-surgeon study is a retrospective review of patients who underwent PEEK cranioplasty. PEEK implants were fashioned from high-resolution CT scans of each patient and sterilized preoperatively before cranioplasty was performed using standard techniques. Computer-designed, patient-specific PEEK implants for cranioplasties were found to be viable alternative when autologous bone grafts are unavailable or unsuitable.
