Kerrier vs. Bone cement (PMMA)

Bone cement (polymethyl methacrylate or PMMA) antibiotic beads are formed by mixing antibiotics, powdered acrylic and a liquid monomer. PMMA has a good degree of compatibility with animal tissue and can deliver antibiotic locally, but poses significant disadvantages when compared to absorbable materials like calcium sulfate:

KERRIER (Medical Grade Calcium Sulfate)Bone Cement (PMMA)
Fully absorbableNon-absorbable – requires 2nd surgery for removal
Does not act as a foreign bodyPotential for bacterial colonization if not removed
Delivers full amount of antibioticDelivers only partial amount of antibiotic
Will stop delivering antibiotic once fully absorbedIf not removed, prolonged sub therapeutic levels increase risk of antibiotic resistance
Low exothermic reactionHigh exothermic reaction decreases the effectiveness of some antibiotics
Complete sterile kit for bead productionNo commercial PMMA bead kit available
