A qualitative method for testing the antimicrobial ability of osteosynthetic fixation material by simulating in vitro contamination by Staphylococcus aureus.

External fixators of serious fractures could be an attractive substrate on which microorganisms can accumulate. Therefore, this study aimed to develop a suitable method for enabling the simulation of a real situation when osteosynthetic fixation material is open for the potential threat of bacterial attack. Agar-based media represented human tissue, and the metallic pin characterized the screw in the fixation.
