Interbody bone implant device
A composite interbody bone implant device is provided including a body having a non-bone composition, such as a polymer, formed into a shape and including one or more cavities. An osteoinductive material, such as bone allograft tissue, may be retained in the one or more cavities of the body. The body is formable via injection molding and/or machining into a shape and size adapted for implantation at a surgical site. The dimensions of the body include a length, a width and a thickness, and the thickness of the body may be less than at least one of the length and width.
1. A bone implant device comprising:
a monolithic body, which comprises a non-bone composition formed into a shape and including at least one cavity, the composition comprising a polymer comprising poly-ether-ketone-ketone (PEKK), poly-ether-ether-ketone (PEEK), or a combination thereof; and
a biocompatible material provided within the at least one cavity of the body, wherein the at least one cavity passes through the body, wherein the body is formable into a shape and size configured for implantation at a surgical site, wherein the biocompatible material comprises demineralized bone matrix fibers and demineralized bone matrix chips in a 30:60 ratio, and the demineralized bone matrix chips are surface demineralized and the demineralized bone fibers are fully demineralized,
wherein the device comprises a surface area and about 5% to about 50% or about 10% to about 20% of the surface area is configured to contact host bone from an intervertebral endplate,
wherein the biocompatible material comprises allograft bone material and the allograft bone material comprises from about 10% to about 60% by weight of the device or from about 15% to about 30% by weight of the device.
2. A device of claim 1 , wherein the non-bone composition includes at least one of an additional polymer, ceramic, metal or combinations thereof.
3. A device of claim 1 , wherein the body includes a plurality of cavities distributed throughout surfaces of the body.
