Abstract

An orthopedic implant having an implant body including a bone interface surface having a bone interface structure protruding therefrom. The bone interface structure includes a proximal portion of the bone interface structure adjacent the bone interface surface and a distal portion of the bone interface structure extending from the proximal portion of the bone interface structure, wherein the distal portion of the bone interface structure configured to be disposed at least partially into a bone structure during use.

Claims

1. An orthopedic implant, comprising:

an implant body comprising a bone interface surface having a bone interface structure protruding therefrom, wherein the bone interface structure comprises;

a proximal portion of the bone interface structure adjacent the bone interface surface; and

a distal portion of the bone interface structure extending from the proximal portion of the bone interface structure, wherein the distal portion of the bone interface structure configured to be disposed at least partially into a bone structure during use.

2. The orthopedic implant of claim 1, wherein the proximal portion of the bone interface structure comprises one or more openings configured to receive a bonding agent within the one or more openings during use.

3. The orthopedic implant of claim 1, wherein the proximal portion of the bone interface structure comprises a web structure comprising a plurality of struts connected at nodes.

4. The orthopedic implant of claim 1, wherein the distal portion of the bone interface structure comprises a web structure comprising a plurality of struts connected at nodes.

5. The orthopedic implant of claim 1, wherein the distal portion of the bone interface structure comprises rod structure.

6. The orthopedic implant of claim 1, wherein the distal portion of the bone interface structure comprises at least one of a V-shaped structure, a U-shaped structure, and a hook-shaped structure.

7. The orthopedic implant of claim 1, wherein the bone interface structure comprises one or more stops configured to inhibit insertion of the proximal portion of the bone interface structure into the bone structure.

8. The orthopedic implant of claim 1, wherein the distal portion of the bone interface structure is configured to be pressed into the bone structure such that the distal portion bone interface structure at least partially penetrates the bone structure.

9. The orthopedic implant of claim 1, wherein the implant body comprises an injection port comprising a conduit configured to route a bonding agent into the bone interface structure.

10. The orthopedic implant of claim 1, wherein one or more portions of the bone interface structure comprise a biologic, growth factor or pain medication disposed thereon.

11. The orthopedic implant of claim 1, wherein the orthopedic implant comprises one or more of a large joint implant, a small joint implant, a trauma implant, a spine implant, a cranial maxi facial implant, a dental implant a knee implant, an ankle implant, a foot implant and a shoulder implant.

12. The orthopedic implant of claim 1, wherein the distal portion of the bone interface structure is configured to inhibit uplift of the orthopedic implant during use.

13. The orthopedic implant of claim 1, wherein the distal portion of the bone interface structure is configured to inhibit migration of the orthopedic implant during use.

14. The orthopedic implant of claim 1, wherein the distal portion of the bone interface structure is configured to inhibit rotation of the orthopedic implant during use.

35. The orthopedic implant of claim 3′

1 claim 1, wherein the distal portion comprises a structure extending from the proximal portion.

36. The orthopedic implant of claim 3′

1 claim 1, wherein the proximal portion comprises a first structure directly coupled to the bone interface surface of the implant and the distal portion comprises a second structure directly coupled to the bone interface surface.

50. The orthopedic implant of claim 1, wherein the proximal portion of the bone interface structure extends a first distance from the bone interface surface;

and the distal portion of the bone interface structure extends a second distance from the bone interface surface, wherein the second distance is greater than the first distance.

15. An implant, comprising:

an implant body; and

a bone interface structure, comprising;

a distal bone interface structure; and

a proximal bone interface structure located between the distal bone interface structure and the implant body,

wherein the distal portion of the bone interface structure configured to be disposed at least partially into a bone structure during use, and

wherein the proximal portion of the bone interface structure is configured to be disposed in a gap between the bone structure and the implant body during use.

16. A method for providing an orthopedic implant, comprising:

inserting, into a bone structure, a distal portion of a bone interface structure coupled to an implant body such that a gap is formed between the implant body and the bone structure, and wherein the gap is spanned by a proximal portion of the bone interface structure extending between the implant body and the distal portion of the bone interface structure; and

providing a bonding agent within the gap.
