Abstract:
The purpose of this study was to record the effect of the addition of vancomycin on the compression strength of antibiotic-loaded bone cement and to compare the results with the international standards (ISO 5833-2). The formulations tested were: Palamed G and Copal. Vancomycin concentrations of 2.5%, 5% and 10% per powder weight were added. Samples of Palamed G with 5% vancomycin and non-standardised mixing procedures were also tested. The ISO requirements for the testing procedures were followed. None of the combinations tested fall short of the ISO standards for compression strength. Copal with 10% and Palamed G with 5% vancomycin and non-standardised mixing procedures, however, did not significantly exceed them. The addition of up to 5% vancomycin per powder weight to the Palamed G and Copal bone cements can be considered safe. Care should be given to the mixing procedure of the cement, as it significantly affects its compression strength.

Strength of Cement
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in ASTM C...
