Impaction durability of porous polyether-ether-ketone (PEEK) and titanium-coated PEEK interbody fusion devices

Although recent surface modifications to interbody fusion devices are beneficial for osseointegration, they may be susceptible to damage and wear during impaction. The current study found porous PEEK devices to show minimal damage during simulated cervical impaction, whereas titanium-coated PEEK devices lost substantial titanium coverage.
