<p>The invention is directed toward a sterile malleable bone composition for application to a bone defect site to promote new bone growth at the site comprising a mixture of demineralized osteogenic bone powder with a particle size ranging from about 250 to about 750 microns and surface demineralized cortical bone rods having a diameter ranging from 1.0 mm to 5.00 mm or larger bone chips. The surface demineralized cortical bone rods have diameter to length ratio ranging from 1:2 to 1:20. The demineralized bone powder range from about 25 to about 30 % of the weight of the composition and the cortical bone rods range from 5 % to about 10 % of the weight of the composition with the carrier being selected from the high molecular weight hydrogel in aqueous solution having a high molecular weight over 700,000 Daltons and ranging from about 2.0 % to about 5.0 % by weight of the carrier solution.</p> |
