Abstract

Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail.

First claim

What is claimed is:

1. An intramedullary system configured to stabilize bone, the system comprising:
an intramedullary nail having:
a body elongated along a first axis, the body having a proximal portion and a distal portion, the body having an opening in the proximal portion, the opening having a shoulder and circumferential slot capable of non-threadably connecting to an insertion instrument;
a first aperture formed in the distal portion and transverse to the first axis;
a second aperture formed in the distal portion and transverse to the first axis;
a third aperture formed in the distal portion and transverse to the first axis;
a first elongated aperture formed in the distal portion and transverse to the first axis;
wherein the first aperture, the second aperture, the third aperture and the elongated aperture are positioned on a first plane; and
wherein the body has a curved shape in an anterior-posterior direction and a straight shape in a lateral direction such that the body is configured to be used either antegrade or retrograde, as well as in a right leg or left leg.

2. The system of claim 1 , wherein the first, second, and third apertures are spaced apart from one another and are disposed distally of the first elongated aperture, the first elongated aperture longitudinally extending along a proximal-distal direction.

3. The system of claim 1 , wherein first and second apertures are threaded.

4. The system of claim 1 , wherein the first, second and third apertures are angled.

5. The system of claim 4 , wherein a degree of angle of the first, second and the third apertures are different.

6. The system of claim 4 , wherein a degree of angle of the first, second and the third apertures is equal.

7. The system of claim 1 , wherein the first, second, and third apertures are configured to each receive a fastening device.

8. The system of claim 1 , further comprising:
a fourth aperture formed in the distal portion and transverse to the first axis; and
a fifth aperture formed in the distal portion and transverse to the first axis.

9. The system of claim 8 , further comprising a second elongated aperture formed in the distal portion and transverse to the first axis.

10. The system of claim 9 , wherein the fourth aperture, the fifth aperture, and the second elongated aperture are positioned on a second plane.

11. The system of claim 10 , wherein the first plane and second plane are perpendicular.

12. An intramedullary nail comprising:
a body elongated along a first axis, the body having a proximal portion and a distal portion, the body having an opening in the proximal portion, the opening having a shoulder and circumferential slot capable of non-threadably connecting to an insertion instrument;
a first aperture formed in the distal portion and transverse to the first axis;
a second aperture formed in the distal portion and transverse to the first axis;
a third aperture formed in the distal portion and transverse to the first axis;
a first elongated aperture formed in the distal portion and transverse to the first axis;
wherein the first aperture, the second aperture, the third aperture and the elongated aperture are positioned on a first plane,
wherein the first elongated aperture is positioned proximal to the third aperture on the distal portion of the intramedullary nail; and
wherein the body has a curved shape in an anterior-posterior direction and a straight shape in a lateral direction such that the body is configured to be used either antegrade or retrograde, as well as in a right leg or left leg.

13. The system of claim 12 , wherein the first, second, and third apertures are spaced apart from one another.

14. The system of claim 12 , wherein first aperture and second aperture are threaded.

15. The system of claim 12 , wherein the first aperture, second aperture, and third aperture are angled.

16. The system of claim 15 , wherein a degree of angle of the first, second and the third apertures are different.

17. The system of claim 16 , wherein a degree of angle of the first, second and the third apertures is equal.

18. The system of claim 12 , further comprising:
a fourth aperture formed in the distal portion and transverse to the first axis;
a fifth aperture formed in the distal portion and transverse to the first axis; and
a second elongated aperture formed in the distal portion and transverse to the first axis.

19. The system of claim 18 , wherein the fourth aperture, the fifth aperture, and the second elongated aperture are positioned on a second plane, and wherein the first plane and the second planes are perpendicular.

20. The system of claim 19 , wherein the first, second, third, fourth and fifth apertures are configured to each receive a fastening device.
