IMPLANT FOR FOCAL TALUS DEFECTS AND METHOD

1 . A talar implant comprising:

at least one body section;

at least one mesh section; and

at least one solid section extending down from the body section, the at least one solid section comprising at least one point.

2 . The talar implant of claim 1 , wherein the at least one body section is semi-spherical.

3 . The talar implant of claim 2 , wherein the at least one body section comprises at least one smooth continuous surface.

4 . The talar implant of claim 1 , wherein the at least one mesh section is configured as a honeycomb pattern comprising a plurality of cells.

5 . The talar implant of claim 1 , wherein the at least one mesh section has a variable porosity.

6 . The talar implant of claim 1 , wherein the at least one mesh section, the at least one body section and the at least one solid section are printed as one piece.

7 . The talar implant of claim 1 , wherein the at least one solid section comprises at least one spike element.

8 . The talar implant of claim 1 , wherein the at least one solid section comprises a plurality of spike elements extending out from the body section.

9 . A kit for inserting a talar implant comprising:

at least one tibial guide;

at least one talar guide;

at least one impactor instrument for inserting the talar implant into a patient's talus.

10 . The kit of claim 9 , wherein the at least one tibial guide has at least one slot configured to accept a cutting tool to cut a tibia in a guided manner along the slot.

11 . The kit of claim 9 , wherein the at least one talar guide is substantially U-shaped and comprises a plurality of holes.

12 . The kit of claim 9 , wherein the impactor has a first end and a second end, wherein the first end is configured as a substantially concave surface.

13 . A method for implanting a talus implant comprising:

identifying a damaged area;

projecting a missing damaged area on a contralateral joint;

printing an implant based upon a mirror image of a portion of the contralateral joint;

applying at least one cutting guide to a bone;

removing at least a portion of a damaged region of the talus;

inserting the talar implant into the talus; and

setting the talar implant within the talus.

14 . The method of claim 13 , wherein the method for setting the talar implant comprises using an impactor to set the talar implant.

15 . The process of claim 13 , wherein the at least one cutting guide comprises at least one of a tibial guide or a talar guide.

16 . The method of claim 15 , wherein the talar guide is configured to receive a pin, and wherein the method further comprises using a reamer guided by the pin on the talar guide to guide the reamer.

17 . The method of claim 13 , wherein the removing at least a portion of a damaged region of the talus comprises using at least one reamer for removing at least a portion of the talus that is either damaged or in a region of a damaged portion of the talus.

18 . The method of claim 13 , further comprising removing a portion of a tibia.

19 . The method of claim 13 , wherein the talar implant has at body, a mesh portion and a solid portion.

20 . The method of claim 19 , wherein the body of the talar implant has a polished surface, and wherein the mesh portion has variable porosity.
