Fig 1.
Cumulative antibiotic release amount in high dose group.
Graphs showing cumulative antibiotic released from cement specimens of (A) Simplex P; (B) Osteobond; (C) PALACOS R; and (D) CMW loaded with high (4g vancomycin) dose preparations of Sterile Vancomycin, Lyo-Vancin or Vanco in broth elution assay for 336 hours. Values are shown as the mean and standard error of the mean for eight specimens in each group.
Fig 2.
Cumulative antibiotic release amount in low dose group.
Graphs showing cumulative antibiotic released from cement specimens of (A) Simplex P; (B) Osteobond; (C) PALACOS R; and (D) CMW loaded with low (1g vancomycin) dose preparations of Sterile Vancomycin, Lyo-Vancin, or Vanco in broth elution assay for 336 hours. Values are shown as the mean and standard error of the mean for eight specimens in each group.
Fig 3.
Ultimate compressive strength in high dose group.
Mean ultimate compressive strength of (A) Simplex P; (B) Osteobond; (C) PALACOS R; and (D) CMW cement samples loaded with high (4g vancomycin) dose preparations of the 3 brands of antibiotics before and after 336-hour broth elution assay relative to cement without antibiotics (control). Values are shown as the mean and standard error for each group.
Fig 4.
Ultimate compressive strength in low dose group.
Mean ultimate compressive strength of (A) Simplex P; (B) Osteobond; (C) PALACOS R; and (D) CMW cement samples loaded with low (1g vancomycin) dose preparations of 3 brands of antibiotics before and after 336-hour broth elution assay relative to cement without antibiotics (control). Values are shown as the mean and standard error for each group.
