Abstract

Objectives: To assess the efficacy of a standard operational procedure to clean flexible intramedullary bone reamers, as well as the sterilization
level, and to show the cytotoxicity of the residual dirtiness of a flexible reamer used in care practice. Methods: Flexible intramedullary bone reamers were
weighed before processing, after challenge contamination and after cleaning. They were contaminated with the Soil Test™, Geobacillus stearothermophilus
suspension, in the concentration of 106 cfu/ml, and bovine bone flour. After processing, the samples were inoculated into a culture medium and
incubated for 21 days. Residual dirtiness of a flexible intramedullary bone reamer used in practice was submitted to in vitro cytotoxicity test. Results:
Despite being sterilized, the samples indicate to accumulated dirtiness and the processing was inefficient. Residual dirtiness presented a cytotoxic effect.
Conclusion: It is recommended that the flexible design of reamers is discontinued by the lack of safety of reprocessing.
