Corrosion on Spinal Implant Constructs: Should Standards Be Revised?

Source

Corrosion is known to occur on modular spinal implants but design features such and material, surface finish, and interconnection characteristics have not been related to corrosion. Literature review was combined with retrieval analysis of thirty-three constructs to identify which design features were associated with corrosion. Corrosion was found consistently on implants where stainless steel components with differing surface finishes (Matte and polished) were designed with rigid interconnections. No clear direction for new standards activity was identified.
