Gentamycin elution from polymethylmethacrylate and bone graft substitute: Comparison between commercially available and home-made preparations.

Polymethylmethacrylate (PMMA) represents the current gold standard as an antibiotic delivery carrier in orthopaedic surgery. Despite the accepted use of local antibiotic carriers, there aren't any conclusive data comparing PMMA to Bone Graft Substitutes. The aim of this study was to compare the elution profile of gentamicin from various preparations of PMMA cements and Herafill beads.
