Surgical implant devices incorporating porous surfaces and a locking plate
A surgical implant device, comprising: a body portion defining a plurality of ports; a plurality of bone screws disposed partially through the plurality of ports defined by the body portion; a locking plate disposed over a head portion of at least one of the plurality of bone screws and engaging a plurality of recesses manufactured into a side of the body portion; and a screw operable for compressing the locking plate against the side of the body portion. Optionally, the surgical implant device further comprising: one or more surfaces comprising a plurality of protruding structures; wherein the body portion and the one or more surfaces comprising the plurality of protruding structures are integrally formed. The one or more surfaces comprising the plurality of protruding structures are formed by an additive manufacturing process.
1. A surgical implant device, comprising:
a metallic body portion defining a plurality of ports, the body portion comprising one or more metallic osteo-porous surfaces osteo-derived from one or more spongy bone surfaces to approximate the texture of the one or more spongy bone surfaces and comprising a plurality of metallic protruding structures disposed one or more of on and through the one or more osteo-porous surfaces, wherein the body portion and the one or more osteo-porous surfaces comprising the plurality of protruding structures disposed one or more of on and through the one or more osteo-porous surfaces are integrally formed, wherein one or more osteo-porous surfaces and the plurality of protruding structures disposed one or more of on and through the one or more osteo-porous surfaces are both configured to promote bony ingrowth;
wherein an exterior surface of each of the plurality of protruding structures is roughened to further promote bony ingrowth;
a plurality of bone screws disposed partially through the plurality of ports defined by the body portion;
a locking plate disposed over a head portion of at least one of the plurality of bone screws and engaging a plurality of recesses manufactured into a side of the body portion; and
a screw operable for compressing the locking plate against the side of the body portion.
2. The surgical implant device of claim 1 , wherein the one or more surfaces comprising the plurality of protruding structures are formed by an additive manufacturing process.
3. The surgical implant device of claim 1 , wherein the plurality of protruding structures comprise a plurality of needles.
4. The surgical implant device of claim 1 , wherein the plurality of protruding structures comprise a plurality of needles that are disposed perpendicular to the body portion.
5. The surgical implant device of claim 1 , wherein the plurality of protruding structures comprise a plurality of needles that are disposed at an angle to the body portion.
6. The surgical implant device of claim 1 , wherein the plurality of protruding structures comprise a plurality of needles that comprise titanium.
7. The surgical implant device of claim 1 , wherein the body portion defines a hollow interior cavity.
8. The surgical implant device of claim 1 , wherein the body portion defines one or more ports that are configured to allow bony ingrowth.
9. The surgical implant device of claim 1 , wherein the surgical implant device comprises an anterior lumbar interbody fusion cage or a cervical cage.
