Studies Indicate Titanium-Coated PEEK Interbody Devices Generate Debris During Impaction into Disc Space


Biomechanical study results have demonstrated that titanium-coated polyetheretherketone (PEEK) implants may be susceptible to the generation of particulate debris during impaction into the disc space. 

Specifically, the study showed that 26% of the teeth on titanium-coated PEEK implants lost coating material when subjected to shear loading, with more than half of the particles of a size range that allows for phagocytosis.

Study results indicate that the proprietary subtractive manufacturing process used to create Titan’s Endoskeleton® devices produced no impaction-related debris.

In 4Q15, Titan Spine plans to launch next-generation nanoLOCK™ surface technology that features various topographies at the macro, micro, and nano (MMN™) levels.
