ABSTRACT

PURPOSE:

To analyze the physical properties of demineralized bone matrix (DBM) and self-setting calcium phosphate cement (CPC) composite for its compatibility to percutaneous kyphoplasty. MATERIALS AND

METHODS:

According to tap volume method, DBM was mixed with CPC in variable ratio 0%, 20%, 30%, 40% and 50%. Distilled water was used as a hardening fluid. Its properties, including injectability, mold applicability, setting time and its behavior, maximum temperature, and mechanical strength, were analyzed.

RESULTS:

The DBM-CP composites has a good injectability and mold applicability, a maximum temperature of less than 5oC, a initial setting time of 3 to 10 minutes. The outer surface of DBM-CP composites showed their even distribution in optical microscopy. Injectability, mold applicability and compressive strength were in inverse proportion to the amounts of DBM.

CONCLUSION:

This study suggests that the DBM-CP composites has a good injectability and mold applicability with a low setting temperature and even distribution of compound. Therefore this composite might be used as a substitute of PMMA in kyphoplasty.
