Abstract:
[Objective]To study the influence of hydroxypropyl methyl cellulose(HPMC) on injectability of calcium phosphate cements(CPC).[Method]Calcium phosphate cement(ICPC) with different content of HPMC(0～4%) was prepared.Injectability coefficient and consistency were tested to evaluate the injectability of the cements.[Result]Injectability increased as HPMC content increased.CPC injectability coefficient reached to 95% with lowest consistency when HPMC increased to 2%.CPC with 2% HPMC could be injected from syringe completely.Injectability began decrease when HPMC beyond 3%.Injectability decreased to 90% as HPMC increased to 4%,2% HPMC increased the injectability and decreased the consistency significantly,without any influence of setting time.[Conclusion]Rheology and injectability of CPC can be improved by HPMC significantly,Injection of CPC with 2% HPMC can be used for mini-invasive orthopedic surgery.
