Table 1 Antibiotic ratio of the six dual antibiotic-loaded bone cement (dALBC) preparations

Group	PMMA bone cement	Premixed gentamicin	Manually added gentamicin	Total amount of gentamicin	Premixed vancomycin	Manually added vancomycin	Total amount of vancomycin
A	Copal spacem	0	0,5 g	0,5 g	0	2 g	2 g
B	*Copal spacem*	0	0,5 g	*0,5 g*	0	4 g	*4 g*
C	Palacos R + G	0,5 g	0	0,5 g	0	2 g	2 g
D	*Palacos R* + G	0,5 g	0	*0,5 g*	0	4 g	*4 g*
E	Copal G + V	0,5 g	0	0,5 g	2 g	0	2 g
F	*Copal G* + V	0,5 g	0	*0,5 g*	2 g	2 g	*4 g*

From each of the three PMMA bone cements two different preparations were tested, a low concentration with 2 g of vancomycin (Group A, C and E;) and a high concentration preparation with 4 g of vancomycin (Group B, D and F; all written in cursive letters)
