Abstract
Official abstract text for this publication.
A composition includes calcium sulfate hemihydrate, stearic acid, an accelerant, and a mixing solution. The composition can be injected, e.g., through a needle, and is capable of setting, e.g., in vivo, in a relatively short period of time to a relatively high hardness.
First claim
Opening claim text (preview).
What is claimed is: 1. A bone graft substitute composition kit, comprising: a powder mixture comprising greater than about 90 weight percent calcium sulfate hemihydrate, an accelerant for accelerating conversion of calcium sulfate hemihydrate to calcium sulfate dihydrate, the accelerant present in an amount of less than about 0.5 percent by weight of the powder mixture, and stearic acid in an amount of at least about 1.0 percent by weight of the powder mixture; an aqueous mixing so…
