Abstract

Disclosed are dual-phase cement precursor systems and related methods and kits. The cement precursor systems are composed of a first and second discrete phases, at least one of which is aqueous. When combined, the cement precursor phases form a cement that is suitable as a bone graft material for bone repair procedures. In preferred embodiments, the materials are highly biocompatible, osteoinductive, and bioresorbable. A number of different but not mutually exclusive cement chemistries may be employed in the cement precursor systems. For instance, hydrogel-forming polymer cements, carboxyl/calcium cements, or calcium phosphate cements may be employed.
