Abstract: A flexible, demineralized unitary bone sheet comprised of cortical cancellous bone having a residual calcium weight of 3.0% to 8.0% with a hyaluronic acid component having a molecular weight of 700,000 to 1,500,000 with the weight of the same ranging from 1% to about 5% of the total sheet weight. The bone sheet is adapted for use during the in vivo repair of a mammalian or animal skeletal system with the thickness of the cortical cancellous sheet ranging from 2.0 mm to about 8.0 mm. The bone sheet has sufficient flexibility to allow the sheet to be shaped to conform to the configuration of a skeletal region to be repaired and sufficient tensile strength to allow the sheet to be so shaped without damage to the sheet.

Abstract: A serrated bone graft section for graft in a patient includes a body portion cut from elongate cortical bone, the body portion having a sidewall portion, the body portion having substantially planar end faces at opposite ends of said body portion, each of the end faces having a plurality of grooves cut therein so as to form serrations in each of the end faces.
