The effect of the incorporation of amphotericin B into bone cement was examined; as literature suggests, this may be a feasible method for the treatment of periprosthetic fungal infections. Addition of antifungal increased the compressive strength of the bone cement-a statistically significant amount from 107 +/- 2.3 to 121 +/- 1.5 MPa. Elution of tobramycin and amphotericin B was quantified using ultraviolet-visible spectroscopy. Spectroscopy showed that 18% of the antibiotic was released during the first week, with most released in the first 24 hours. The elution of antifungal, however, was unable to be detected after 1 week, with less than 0.03% released. Amphotericin B does not weaken bone cement. Its inability to be delivered at a clinically significant dose gives no clear indication for its incorporation into cement.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
