COMPOSITE BONE GRAFT CEMENT COMPRISING CALCIUM SULFATE DIHYDRATE AND BRUSHITE |
摘要 |
<p>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 .beta.-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.</p> |
