Intramedullary implant and method of use

1. A bone implant comprising:

a proximal end;

a distal end;

a first portion extending between the proximal and distal ends having a maximum portion height and a minimum portion height; and

a second portion extending between the proximal and distal ends having a maximum portion height and a minimum portion height, the second portion connected to the first portion at the proximal end and the distal end and at least one of the first portion and the second portion being moveable relative to the other of the first portion and the second portion so as to transition the bone implant between a relaxed state wherein the first and second portions are separated by a first distance and a contracted state wherein the first and second portions are separated by a second distance different from the first distance, wherein at least one of the proximal end and the distal end have the minimum portion height,

wherein the first and second portions are biased away from each other so that the bone implant is configured to be transitioned to or maintained in the contracted state via engagement with an instrument at a single contact point on each of the first portion and the second portion.

2. The implant of claim 1 , further comprising an anchor element on at least one of the first portion and the second portion.

3. The implant of claim 2 , wherein the anchor element is a plurality of barbs extending from at least one of the first and second portions.

4. The implant of claim 3 , wherein a first set of barbs are positioned adjacent the proximal end of the implant and extend from the first and second portions so that ends of the first set of barbs face a first direction, and a second set barbs are positioned adjacent the distal end of the implant and extend from the first and second portions so that ends thereof face in a second direction opposite the first direction.

5. The implant of claim 4 , wherein the first and second portions taper outwardly from the proximal and distal ends so that a maximum width of the implant is positioned between the proximal and distal ends.

6. The implant of claim 5 , wherein the first and second portions each include an engagement surface for engaging an instrument, the engagement surfaces of the first and second portions are disposed at a location of the maximum width of the implant and between the first and second sets of barbs.

7. The implant of claim 1 , wherein the first and second portions are bent along their length so that the proximal end is oblique to the distal end.

8. The implant of claim 1 , further comprising a first flange extending from the first portion towards the second portion and a second flange extending from the second portion towards the first portion.

9. The implant of claim 8 , wherein the first and second flange members are spaced from one another when in the relaxed state and contact one another when in the contracted state.

10. The implant of claim 8 , wherein the first and second flanges extend from inner surfaces of the first and second portions and are located along a length of the first and second portions at a position of maximum width of the bone implant.

11. The implant of claim 1 , wherein the proximal end has a width greater than a width of the distal end.

12. The implant of claim 1 , wherein the first and second portions define a channel extending between the first and second portions and towards the proximal and distal ends, the channel adapted to accept a guide wire therein.

13. The implant of claim 12 , wherein the channel is defined between inner surfaces of the first and second portions and upper surfaces of the proximal and distal ends.

14. A bone implant comprising:

a monolithic bone implant including first and second elongate portions and proximal and distal end portions, the first and second elongate portions each connecting to the proximal and distal end portions so as to form a space that is confined between the first and second elongate portions and proximal and distal end portions, the first and second elongate portions and proximal and distal end portions also defining a channel that extends along a length of the implant from the distal end portion to the proximal end portion, the channel being configured to slidingly receive a guide wire.

15. The implant of claim 14 , wherein the space is defined by inner surfaces of the first and second elongate portions and inner surfaces of the proximal and distal end portions, and the channel is defined by inner surfaces of the first and second elongate portions and upper surfaces of the distal and proximal end portions.

16. A bone implant, comprising:

a proximal end;

a distal end;

a first portion;

a second portion connected to the first portion at the proximal and distal ends of the bone implant;

a first flange extending from the first portion towards the second portion; and

a second flange extending from the second portion towards the first portion, wherein the first and second portions are biased away from each other and have a relaxed state where the first flange and second flange are separated by a first distance and a contracted state wherein the first flange and the second flange are separated by a second distance different from the first distance.

17. The implant of claim 16 , wherein the first and second portions have a portion height, the proximal and distal ends of the implant have an end height, and the first and second flanges have a flange height smaller than the portion height.

18. The implant of claim 17 , further comprising a channel defined between the first and second portions, the channel having a height defined by the difference between the portion height and the flange height.

19. The implant of claim 17 , further comprising a channel defined between the first and second portions and within the portion height, and the channel ending above the end height at the proximal and/or distal end, the end height being smaller than the portion height.
