Characterization of the Adherence Patterns and Biofilm Density of Commonly Encountered Bacterial Pathogens to Spinal Instrumentation of Differing Compositions

Infections are one of the most pressing problems in orthopaedic surgery.


No single implant material is able to reduce bacterial adherence of all of the pathogens tested.
Cobalt Chromium and PEEK have highest level of bacterial adherence.
Stainless Steel and Titanium Alloy have the least amount of bacterial adherence.
Adherence appears to be guided by surface microtopography of materials.
