[ EN ]

I claim:

1. An orthopedic implant comprising:

a bridge including a first end and a second end;

a first leg extending from the first end of the bridge; and

a second leg extending from the second end of the bridge;

wherein the bridge comprising a metal spacer structure provided in between the first leg and the second leg and extending from the bridge in the same direction as the first and second legs, wherein the metal spacer structure is configured to be inserted between two osteotomy bone surfaces.

2. The orthopedic implant of claim 1, further comprising additional legs provided between the metal spacer structure and the first leg and/or the second leg.

3. The orthopedic implant of claim 1, wherein the metal spacer structure has a porous perforated structure for promoting bone ingrowth into the metal spacer structure after the metal spacer structure is positioned between the two osteotomy bone surfaces.

4. The orthopedic implant of claim 1, wherein the metal spacer structure has a triangular wedge shaped profile and having two planar surfaces facing the first and second legs.

5. The orthopedic implant of claim 1, wherein the metal spacer structure has a trapezoidal shaped profile and having two planar surfaces facing the first and second legs.

6. The orthopedic implant of claim 1, wherein at least the bridge and the legs are made from a shape memory material.

7. An orthopedic implant comprising:

a bridge including a first end and a second end, wherein each of the first and second ends of the bridge is provided with one or more holes for receiving bone screws; and

a first leg and a second leg provided between the first end and the second end and extending from the bridge.

8. The orthopedic implant of claim 7, wherein the holes for the bone screws are threaded to accommodate threaded heads of locking screws.

9. The orthopedic implant of claim 7, wherein at least the bridge and the legs are made from a shape memory material.

10. An orthopedic implant comprising:

a bridge including a first end and a second end;

a first leg extending from the first end of the bridge; and

a second leg extending from the second end of the bridge;

wherein the at least the bridge portion of the orthopedic implant is made of a shape memory material such that the bridge is movable between an insertion shape and an implanted shape, wherein when in the insertion shape the bridge is straight, and when in the implanted shape the bridge is bowed in a direction opposite from the extension direction of the first and second legs and urges the first and second legs toward each other.

11. An orthopedic implant comprising:

a bridge having a longitudinal axis and including a first end and a second end;

a bridge extension provided at each of the first end and the second end, wherein the bridge extensions extend in a transverse direction with respect the longitudinal axis of the bridge; and

a plurality of legs extending from each of the bridge extensions;

wherein the orthopedic implant being made of a shape memory material such that the orthopedic implant is movable between an insertion shape and an implanted shape,

wherein in the implanted shape, the plurality of legs are urged in more than one preset directions to produce compression load in the more than one preset directions.

12. The orthopedic implant of claim 11, wherein in the implanted shape, the more than one preset directions comprise at least one direction that produces compression in a plane that is in-line with the longitudinal axis of the bridge.

13. The orthopedic implant of claim 11, wherein in the implanted shape, the more than one preset directions comprise at least one direction that produces compression in a plane that is transverse to the longitudinal axis of the bridge.

14. The orthopedic implant of claim 13, wherein the transverse direction is non orthogonal to the longitudinal axis of the bridge.

15. The orthopedic implant of claim 11, further comprising one or more legs extending from the bridge between the first and second ends.
