Abstract

Bone plates for engaging bone members are described herein. The bone plates can receive one or more screws to secure the bone plates to an underlying bone member. The one or more screws can be inserted into bone plate holes that can be considered locking or non-locking. The bone plates described herein can have particular combinations of locking and/or non-locking holes. In addition, instruments such as distal and proximal aiming guides can accompany the bone plates to guide one or more screws into the bone plates.

First claim

The invention claimed is:

1. A tibia bone plate comprising:
a head including a plurality of bone screw holes;
a shaft disposed distally of the head, the shaft including:
a first set of holes having first and second locking holes longitudinally spaced from each other; and
a second set of holes disposed proximally of the first set of holes and having a dynamic compression slot and a third locking hole longitudinally spaced from each other,

wherein the first set of holes and the second set of holes are disposed on the shaft such that the first locking hole is directly adjacent to the second locking hole and the dynamic compression slot is directly adjacent to the second locking hole and the third locking hole,
an aiming arm having a proximal end, a distal end, a first side, and a second side, the aiming arm comprising a plurality of openings, wherein each of the plurality of openings is spaced at predetermined intervals between the proximal end and the distal end,
an attachment guide operatively connected to the first side of the proximal end of the aiming arm, the attachment guide including at least one opening that is coaxial with at least one bone screw hole in the plurality of bone screw holes in the neck portion of the bone plate; and
an attachment post having a first and a second end, wherein the attachment post is operable to pass through the at least one opening in the attachment guide and the bone screw hole in the neck portion of the bone plate;
wherein the first end of the attachment post is operatively connectable to the opening in the attachment guide and the second end is operatively connectable to the bone screw hole in the neck portion of the bone plate, and
wherein the second end of the attachment post includes at least one ball end pin and a stabilizing protrusion configured to engage with the neck portion of the bone plate.

2. The tibia bone plate of claim 1 , wherein every locking hole is a fixed angle locking hole.

3. The tibia bone plate of claim 1 , wherein the first dynamic compression slot is a bi-directional dynamic compression slot.

4. The tibia bone plate of claim 1 , wherein the shaft further comprises a third set of holes longitudinally spaced from each other and disposed proximally of the second set of holes, the third set including fourth and fifth locking holes.

5. The tibia bone plate of claim 4 , wherein the shaft further comprises a fourth set of holes longitudinally spaced from each other and disposed distally of the first set of holes, the fourth set including a sixth locking hole and a bi-directional dynamic compression slot.

6. The tibia bone plate of claim 1 , wherein the shaft further comprises a group of a locking hole and a dynamic compression slot longitudinally spaced from each other and disposed distally of the first set of holes.

7. The tibia bone plate of claim 6 , wherein the locking hole of the group is disposed distally of the dynamic compression slot of the group.

8. The tibia bone plate of claim 1 , further comprising a neck disposed between the head and the shaft, and comprises at least three kickstand holes.

9. The tibia bone plate of claim 1 , wherein the plurality of bone screw holes in the head includes a first row of bone screw holes and a second row of bone screw holes.

10. The tibia bone plate of claim 1 , wherein the head further comprises at least one k-wire hole.

11. The tibia plate of claim 1 , wherein the shaft further comprises a group of a fixed angle locking hole and a bi-directional dynamic compression slot longitudinally spaced from each other and disposed distally of the first set of holes.

12. The tibia plate of claim 11 , wherein the locking hole of the group is disposed distally of the dynamic compression slot of the group.

13. A tibia bone plate comprising:
a head including a plurality of bone screw holes and k-wire holes;
a shaft disposed distally of the head, the shaft including:
a first set of holes having first and second fixed angle locking holes longitudinally spaced from each other; and
a second set of holes disposed proximally of the first set of holes and having a bi-directional dynamic compression slot and a third fixed angle locking hole longitudinally spaced from each other;

wherein the first and second set of holes are adapted to receive a bone screw and the hole disposed most distally among the first and second set of holes is a fixed angle locking hole,
wherein the first set of holes and the second set of holes are disposed on the shaft such that the first fixed angle locking hole is directly adjacent to the second fixed angle locking hole and the dynamic compression slot is directly adjacent to the second fixed angle locking hole and the third fixed angle locking hole,
an aiming arm having a proximal end, a distal end, a first side, and a second side, the aiming arm comprising a plurality of openings, wherein each of the plurality of openings is spaced at predetermined intervals between the proximal end and the distal end,
an attachment guide operatively connected to the first side of the proximal end of the aiming arm, the attachment guide including at least one opening that is coaxial with at least one bone screw hole in the plurality of bone screw holes in the neck portion of the bone plate; and
an attachment post having a first and a second end, wherein the attachment post is operable to pass through the at least one opening in the attachment guide and the bone screw hole in the neck portion of the bone plate;
wherein the first end of the attachment post is operatively connectable to the opening in the attachment guide and the second end is operatively connectable to the bone screw hole in the neck portion of the bone plate, and
wherein the second end of the attachment post includes at least one ball end pin and a stabilizing protrusion configured to engage with the neck portion of the bone plate.

14. The tibia bone plate of claim 13 , wherein the shaft further comprises a third set of fixed angle locking holes longitudinally spaced from each other and disposed proximally of the second set of holes.

15. The tibia bone plate of claim 14 , wherein the shaft further comprises a fourth set of holes longitudinally spaced from each other and disposed distally of the first set of holes, the fourth set including a sixth fixed angle locking hole and a bi-directional dynamic compression slot disposed proximally of the sixth locking hole.

16. The tibia bone plate of claim 13 , further comprising a neck disposed between the head and the shaft, and comprises at least three kickstand holes.

17. The tibia bone plate of claim 13 , wherein the plurality of bone screw holes in the head includes a first row of bone screw holes and a second row of bone screw holes.

18. The tibia bone plate of claim 17 , wherein the head further comprises at least one k-wire hole.

19. The tibia bone plate of claim 13 , wherein the plurality of bone screw holes in the head includes a first row of bone screw holes and a second row of bone screw holes disposed distally of the first row of bone screw holes and are larger than the first row of holes.

20. The tibia bone plate of claim 13 , further comprising a plurality of spaced indentations configured to receive an aiming guide.
