Method and apparatus for pre-forming a high tibial osteotomy

1. An osteotomy implant comprising:

a porous portion including a first part with a first sidewall and a second part with a second sidewall, a clearance is defined between the first sidewall and the second sidewall;

a solid portion abutting the porous portion, the first and the second sidewalls extending from the solid portion to define the clearance; and

a hinge portion of the solid portion coupled to the first part and the second part;

wherein the hinge portion is configured to enable the implant to be changed from a first configuration to a second configuration the implant further comprising an adjustment member, wherein the adjustment member extends from the first part to the second part across the clearance defined between the first part and the second part; wherein rotation of the adjustment member in a first direction draws the first part and the second part together, and rotation of the adjustment member in a second direction pushes the first part and the second part apart.

2. The osteotomy implant of claim 1 , wherein the porous portion includes at least one of a metallic, PEEK, or PEKK.

3. The osteotomy implant of claim 1 , wherein the porous portion includes a porous upper surface and a porous lower surface configured to receive bone ingrowth.

4. The osteotomy implant of claim 3 , wherein the solid portion is coupled to an outer surface of the porous portion, the osteotomy implant formed by additive manufacturing.

5. The osteotomy implant of claim 4 , wherein the solid portion is integral with the outer surface of the porous portion and is load bearing.

6. The osteotomy implant of claim 1 , further comprising a plurality of solid, spaced apart, load bearing ribs with the porous portion therebetween.

7. The osteotomy implant of claim 1 , wherein the solid portion includes at least one of a metallic, PEEK, or PEKK.

8. The osteotomy implant of claim 1 , wherein the implant is monolithic.

9. An osteotomy implant comprising:

a generally “U” shaped loadbearing porous portion including a first part and a second part, the first part includes a first inner surface that opposes a second inner surface of the second part, a clearance is defined between the first inner surface and the second inner surface;

a solid portion coupled to both a first outer surface of the first part and a second outer surface of the second part, the first outer surface is opposite to the first inner surface and the second outer surface is opposite to the second inner surface; and

a flexible hinge portion of the solid portion;

wherein the implant is bendable at the flexible hinge portion to compress or expand the implant;

wherein the flexible hinge portion is configured to enable the implant to be changed from a first configuration to a second configuration upon actuation of an adjustment member at the clearance, the first and the second parts are closer together in the second configuration than in the first configuration.

10. The osteotomy implant of claim 9 , wherein both the porous portion and the solid portion include at least one of a metallic, PEEK, or PEKK.

11. The osteotomy implant of claim 9 , wherein the adjustment member includes a fastener extending from the first part to the second part across the clearance defined between the first part and the second part, rotation of the fastener in a first direction draws the first part and the second part together, rotation of the fastener in a second direction pushes the first part and the second part apart.

12. The osteotomy implant of claim 9 , wherein the adjustment member is arranged in the clearance and extends from the first part to the second part, actuation of the adjustment member in a first direction draws the first part and the second part together, actuation of the adjustment member in a second direction opposite to the first direction moves the first part and the second part apart.

13. The osteotomy implant of claim 9 , wherein the first and the second inner surfaces extend directly from the solid portion.

14. The osteotomy implant of claim 13 , wherein the first and the second inner surfaces extend linearly.

15. The osteotomy implant of claim 13 , wherein the first and the second inner surfaces define the clearance as wedge-shaped.

16. An osteotomy implant comprising:

a porous portion including a first part and a second part that defines a clearance therebetween;

a solid portion abutting the porous portion; and

a hinge portion of the solid portion coupled to the first part and the second part, the hinge portion is configured to enable the implant to be changed from a first configuration to a second configuration; and

an adjustment member configured to change the implant from the first configuration to the second configuration;

wherein the adjustment member includes a fastener extending from the first part to the second part across the clearance defined between the first part and the second part, rotation of the fastener in a first direction draws the first part and the second part together, rotation of the fastener in a second direction pushes the first part and the second part apart.
