Claim Text:
1. A settable osteostimulative bone graft putty composition consisting essentially of: a bioactive glass osteostimulative particulate component consisting essentially of a long-term bioactive glass osteostimulative particulate component characterized by a slow absorption rate in the human body and a short-term bioactive glass osteostimulative particulate component characterized by a faster absorption rate in the human body than said long-term bioactive glass osteostimulative particulate component; said long-term component having particle sizes greater than 90 micrometers and said short-term component having particle sizes of less than 90 micrometers; said long-term component comprising about 60% to 90% of said bioactive glass osteostimulative particulate component dry weight and said short-term component comprising about 40% to 10% of said bioactive glass osteostimulative particulate component dry weight; a binder component consisting essentially of a calcium sulfate component characterized by a fast setting time and a calcium silicate component characterized by a slower setting time in comparison to said calcium sulfate component; and water; said bioactive glass osteostimulative particulate component and said binder component mixable in said water to form said putty, said putty retaining shape and supporting physiologic loading of up to 40 MPa after setting.
