Abstract:
1. A sterile malleable bone composition for application to a bone defect site to promote new bone growth at the site comprising a mixture of partially demineralized osteoinductive and osteoconductive bone material having a calcium content ranging from above 4% to about 8% with a particle size ranging from about 100 to about 800 microns, the bone material ranging from about 25 to about 35% of the weight of the composition, the carrier comprising a hydrogel component in a phosphate buffered aqueous solution, said hydrogel component comprising sodium hyaluronate and its derivatives, and having a high molecular weight ranging from seven hundred thousand to three million Daltons with a stable viscosity from 22° to about 37° C. and ranging from about 0.75% to about 5.0% by weight of the aqueous carrier solution.
