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 |
