Materials PEEK power
Polyether ether ketone (PEEK) has become a cornerstone biomaterial in spinal implants and is increasingly used in cranial implants thanks to its mechanical properties that more closely match bone than metals and its radiolucent imaging profile. As additive manufacturing matures and patient-specific devices gain regulatory acceptance, analysts say the material is set to grow faster than the wider spinal fusion implants market over the coming decade. Liam Critchley reports.
P
olyether ether ketone (PEEK) is a high- performance, implant-grade polymer that has seen broad clinical adoption in medical devices, particularly in the spine, because its mechanical properties and compliance are close to bone and can be tailored, for example, with carbon-fibre reinforcement, to better approximate bone stiffness. When coupled with its excellent biocompatibility, resistance to chemical and hydrolytic degradation in bodily environments, radiolucency that avoids metal-related artefacts in medical imaging and facilitates clearer assessment of the surrounding bone and implant, and its stability across a range of temperatures, it has become a go-to material for a range of medical devices. Advancements in surgical technologies are

also shaping the adoption of new implant materials. As Thomas Fleming, medical analyst at GlobalData, explains, “Advancements in navigation and imaging technologies are key drivers of innovation in the global spinal fusion market, significantly improving surgeons’ ability to pinpoint the cause of back pain and visualise the surgical site during procedures, thus enhancing the accuracy of spinal fusion surgeries.”
