The research was financed in the framework of the project Lublin University of Technology-
Regional Excellence Initiative, funded by the Polish Ministry of Science and Higher Education
(contract no. 030/RID/2018/19).
This study presents an analysis of the impact of doping bone cement with saline. The twoingredient
cement, made right before the surgery, is subject to various kinds of organic contaminants
and liquids used in the operating area, such as saline used to cleanse or cool it, during the process
of mounting the prosthesis or bone-filling procedures. The processes of experimental destructive
testing and statistical analysis have shown that, depending on the degree of saline doping, the static
compressive strength parameters may greatly improve (with a low degree of contamination) or
significantly worsen (when the contamination degree is higher). The limit value of the degree of salt
admixture was estimated (2%), with which no statistically significant differences were observed in
the cement strength in relation to the strength of non-contaminated cement.
