Abstract:
2% hydroxypropyl methyl cellulose (HPMC, medical grade, Taian Ruitai Cellulose Co., Ltd.) was added into calcium phosphate cement (Orthopedics Institute of General Hospital of Chinese PLA) and the mixture was put into distilled water to observe whether the surface was corrupt. Some calcium phosphate cement was immersed in water at different time and the residual cement was weighed 24 hours later. The results showed that there was no surface corruption in calcium phosphate cement with 2% HPMC after shake; the residual weight measured 24 hours later showed that 2% HPMC could shorten calcium phosphate cement cohesion time from 4 minutes to 1 minutes. The experiment indicates that 2% HPMC can significantly increase the waterproof performance of calcium phosphate cement, increase the work time and is adaptable in clinical application.
