The invention provides a particulate composition adapted for forming a bone graft substitute cement upon mixing with an aqueous solution, including i) a calcium sulfate hemihydrate powder having a bimodal particle distribution and a median particle size of about 5 to about 20 microns, wherein the calcium sulfate hemihydrate is present at a concentration of at least about 70 weight percent based on the total weight of the particulate composition; ii) a monocalcium phosphate monohydrate powder; and iii) a β-tricalcium phosphate powder having a median particle size of less than about 20 microns. 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.
A particulate composition adapted for forming a bone graft substitute cement upon mixing with an aqueous solution, comprising:
A bone graft substitute cement comprising a mixture of a calcium sulfate dihydrate phase characterized by a first in vivo resorption rate, a brushite phase characterized by a second in vivo resorption rate slower than the first in vivo resorption rate;
A bone graft substitute kit, comprising:
A method for treating a bone defect, comprising:
