We read with interest an elaborate review “Medical application of polyether ether ketone” by Guo et al. It has succinctly touched all key areas related to be revolutionized by polyetheretherketone (PEEK) material. Another very important enterprise that shall be benefited by this biomaterial of diverse usage is the area of three-dimensional (3-D) printing or additive manufacturing. 3-D printing is a current big idea whose time has come and its importance is set to grow by leaps and bounds according to expert opinions. 3-D printing for fabrication of anatomical models for teaching, preoperative planning, and custom-made implants and for development of patient-specific instrumentation is now a reality, and it is an emerging research field. Techniques such as fusion deposition modeling or fused filament fabrication have enabled successful use of PEEK in 3-D printing of vital orthopedic biomaterials. One of the major advantages of PEEK's uses as orthopedic implants are lack of stress shielding. Coating the PEEK implant with silver nanoparticles has been attempted to manage infections by superior antibacterial effects. These breakthroughs might revolutionize future management of implant-related infections. Lightweight and modules closer to native bone favors use of PEEK for various prosthesis like rib prosthesis that may be used as bone replacement following tumor resection.
In a human study, periprosthetic synovial tissue around implants containing Ultra-High-Molecular-Weight Polyethylene (UHMWPE) or carbon fiber reinforced PEEK was obtained during a revision surgery, among which a different type of nonscattered conglomerates was observed without giant-cell reaction in PEEK biomaterial. Most of the past studies are either in-vitro or in-vivo animal model studies assessing PEEK biocompatibility, barring only two human retrieval studies which have been systematically reviewed by Stratton-Powell et al. They concluded that wear particles of PEEK were, in general, in phagocytozable range and their cytotoxicity was within the acceptable limits in comparison to UHMWPE. The authors also advocate for more future human retrieval studies and further characterization of particle properties for more comprehensive insight. As PEEK is bioinert and deficient in osteogenic properties on its own, research to increase its bioactivity is coming up with myriad innovations like coating with nano-sized hydroxyapatite. More discoveries in this area are instrumental for better version of PEEK in future clinical application.
There is not much to write as of now about impact of PEEK on 3-D printing scenario, but ongoing researches indicate fruitful results in coming times. The future, however, holds the answers to the long-term behavior of PEEK in 3-D printing and their combination appears to be constructive, benefitting various surgical disciplines.
