Abstract
At least a portion of the surface of an osteoprosthetic implant is provided with demineralized bone powder adhering thereto. Sorption of the bone particles is accompanied by rapid and deep bone in-growth which firmly anchors the prosthesis to the host bone repair site.
Claims19
An osteoprosthetic device possessing an osteogenic coating composition adhering to at least a portion of a surface thereof,
- wherein said coating composition consists essentially of demineralized bone powder substantially uniformly distributed within a biocompatible, non-bioerodible binding agent whereby as the demineralized bone powder undergoes gradual resorption, new bone ingrowth is induced and replaces the resorbed demineralized bone powder to provide a firm connection between the prosthesis and the pre-existing bone tissue.
An osteoprosthetic device possessing an osteogenic coating composition adhering to at least a portion of a surface thereof,
- the coating composition comprising demineralized bone powder substantially uniformly distributed within a biocompatible, non-bioerodible binding agent.
- wherein the average particle size of the demineralized bone powder is from about 0.1 to about 1.2 cm whereby as the demineralized bone powder undergoes gradual resorption, new bone ingrowth is induced and replaces the resorbed diemineralized bone powder to provide a firm connection between the prosthesis and the pre-existing bone tissue.
An osteoprosthetic device possessing an osteogenic coating composition adhering to at least a portion of a surface thereof,
- the coating composition comprising demineralized bone powder substantially uniformly distributed within a biocompatible, non-bioerodible binding agent,
- wherein the average particle size of the demineralized bone powder is from about 0.2 to about 1 cm whereby as the demineralized bone powder undergoes gradual resorption, new bone ingrowth is induced and replaces the resorbed demineralized bone powder to provide a firm connection between the prosthesis and the pre-existing bone tissue.
