Abstract

The invention provides a particulate composition adapted for forming a bone graft substitute cement upon mixing with an aqueous solution, comprising i) a calcium sulfate hemihydrate powder, wherein the calcium sulfate hemihydrate is present at a concentration of at least about 50 weight percent based on the total weight of the particulate composition; ii) a monocalcium phosphate monohydrate powder; iii) a non-porous β-tricalcium phosphate powder; and iv) a porous β-tricalcium phosphate powder. Bone graft substitute cements made therefrom, a bone graft substitute kit comprising the particulate composition, methods of making and using the particulate composition, and articles made from the bone graft substitute cement are also provided.
