To assess the efficacy of a biodegradable particulate composite bone cement containing gentamicin and vancomycin for prophylaxis and treatment of Staphylococcus aureus osteomyelitis in rats.
Induced tibial osteomyelitis in rats using S. aureus inoculation alongside polymethylmethacrylate (PMMA) cylinders for 3 weeks.
Evaluated treatment efficacy by placing antibiotic-loaded biodegradable cement or PMMA for an additional 3 weeks in established infections, and tested prophylaxis by applying biodegradable cement at the time of inoculation.
Assessed outcomes serially through clinical evaluation, radiographic imaging, and quantitative microbiological culture for colony forming units (CFUs).
Treatment with antibiotic-loaded biodegradable cement significantly reduced bacterial burden compared to controls (p < 0.01).
Prophylactic application of the biodegradable cement completely prevented infection, showing zero positive findings across clinical, radiographic, and quantitative culture analyses.
Therapeutic effectiveness did not differ significantly between antibiotic-loaded biodegradable cement and conventional PMMA at 3 weeks of treatment.
