A bioerodible cement system, which, upon mixing of the system parts, forms a cured bioerodible cement, said system comprising a first part comprising a first bioerodible polymer capable of producing acidic products upon hydrolytic degradation; and a second part comprising a second bioerodible scaffolding polymer which upon crosslinking provides a biopolymeric scaffolding or internal reinforcement for said cured cement is disclosed. In a preferred embodiment, the second bioerodible polymer comprises polypropylene fumarate (PPF), which is cross-linked during curing, desirably by a vinyl monomer such as vinyl pyrrolidone (VP) to form the biopolymeric scaffolding which provides the cured cement with dimensional and geometric stability.
