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 absorbable||Non-absorbable – requires 2nd surgery for removal|
|Does not act as a foreign body||Potential for bacterial colonization if not removed|
|Delivers full amount of antibiotic||Delivers only partial amount of antibiotic|
|Will stop delivering antibiotic once fully absorbed||If not removed, prolonged sub therapeutic levels increase risk of antibiotic resistance|
|Low exothermic reaction||High exothermic reaction decreases the effectiveness of some antibiotics|
|Complete sterile kit for bead production||No commercial PMMA bead kit available|
Medical Grade Calcium Sulfate vs.
Commercial Plaster of Paris:
How does KERRIER medical grade calcium sulfate compare to commercial plaster of Paris purchased at your local store?
|KERRIER (Medical Grade Calcium Sulfate)||Commercial Plaster of Paris (POP)|
|PURITY||99% purity||75-85% purity|
|TOXICITY||Lab tested non-toxic||Unknown toxicity|
|ABSORBABILITY||Fully absorbable||Store-bought POP contains non-absorbable impurities|
|SAFETY||Lab tested safe for animal implantation||Safety unknown|
|STERILITY||Gamma radiation sterilized||Not provided sterile|
|ON DEMAND KIT||Complete sterile kit for bead production||No kit|
|PROCESSING TIME||10 to 60 minutes||Up to 24 hours|
