BoneSource solidification: a comparison between water and sodium phosphate as the solvent.
The purpose of this study was to determine the solidification rates for BoneSource (hydroxyapatite cement) mixed with sterile water versus BoneSource mixed with 0.25 ml of sodium phosphate. The average time for cure for BoneSource mixed with sterile water was 99 minutes, with a SD of 5.3 minutes. The average time for cure for BoneSource and sodium phosphate was 43 minutes, with a SD of 3.6 minutes (P < 0.0003). The average temperature for BoneSource in sterile water was 19.1 degrees C with a SD of 0.082, and the average temperature of BoneSource in sodium phosphate was 20.1 degrees C, with a SD of 0.1. Therefore, sodium phosphate shows that there is a significantly decreased amount of time required to solidify BoneSource and it remains isothermic throughout this reaction.
