Abstract
Calcium phosphate cements are provided. The subject cements comprise amorphous calcium phosphate, at least one additional calcium source, usually an additional calcium phosphate, and a liquid component, such as a physiologically acceptable lubricant. Upon combination of the cement components, a flowable composition capable of setting in vivo into a solid calcium phosphate mineral product, such as hydroxyapatite, is produced. The subject cement compositions find use in a variety of applications, including the treatment of injured or compromised hard tissue.
