Abstract
Methods and compositions for use in bone repair are provided. The subject methods employ a two component calcium phosphate cement having a dry component and a lubricant, wherein the dry component of the cement comprises basic calcium phosphate particles at least partially coated with a partially neutralized acidic calcium phosphate. In the subject methods, the dry component and lubricant of the cement are combined to produce a moldable paste which is capable of hardening into a solid mass. The moldable paste may be introduced at a bone repair site and allowed to harden in situ. Alternatively the paste may be allowed to harden and then shaped to obtain a preformed object useful in bone repair.
