Abstract: A composite allograft bone device comprising a first bone member body with a face that defines a plurality of spaced projections forming a pattern and a second bone member body defining a face that forms a plurality of spaced projections forming a second pattern. The projections in the first face allow the two bodies to be mated together. The mated bodies form a composite bone device which is provided with a throughgoing bore and a threaded rod member mounted in the throughgoing bore extending into and engaging the bone member bodies holding the same together. Alternatively a rod member with a demineralized or knurled outer surface can be press fit into the throughgoing bore engaging the bone member bodies in an interference fit holding the same together. In another embodiment an inner central cancellous bone block is surrounded by plates or a U shaped base constructed of cortical bone material.

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: The invention is directed toward a cartilage repair assembly comprising a shaped structure of subchondral bone with an integral overlying cartilage cap which is treated to remove cellular debris and proteoglycans and milled cartilage in a bioabsorbable carrier. The shaped structure is dimensioned to fit in a drilled bore in a cartilage defect area so that said shaped bone and cartilage cap when centered in the bore does not engage the side wall of the bore in an interference fit and is surrounded by milled cartilage and carrier. A method for inserting the assembly into a cartilage defect area is disclosed.

Abstract: The invention is directed toward a bone block, a bone-tendon-bone assembly and method of tendon reconstruction in which at least one tendon replacement is extended between two bone blocks and fixed within each of two bone tunnels in the bones of a joint using interference screws. Each bone block has a central through going bore and at least one substantially parallel channel longitudinally cut in the exterior of the bone block body in which the ligament replacements are seated. One end of each bone block has a rounded recess leading from the central bore to the exterior parallel channel.
