Abstract

A dynamic bone plate and method of bone compression is disclosed. The dynamic bone plate comprises a first bone plate component and a second bone plate component. The first bone plate component comprises at least one hole configured for receiving bone screws for attachment to a first bone segment; and a male component. The second bone plate component comprises at least one hole configured for receiving bone screws for attachment to a second bone segment; and a female component configured for mating with the male component of the first bone plate component. The male component is adjustable after mating with the female component to adjust a position of the first bone plate component with respect to the second bone plate component and wherein the male component is locked into place with respect to the female component by at least one bone screw inserted through the at least one hole of the second bone plate component causing compression between the first bone segment and the second bone segment to form a corrective construct.

Claims (37)

1. A dynamic bone plate, comprising:

a first bone plate component, comprising:

at least one hole configured for receiving bone screws for attachment to a first bone segment; and

a male component;

a second bone plate component, comprising:

at least one hole configured for receiving bone screws for attachment to a second bone segment; and

a female component configured for mating with the male component of the first bone plate component;

wherein a portion of at least one of the at least one holes in the second bone plate extends into a side portion of the female component;

wherein the male component is adjustable after mating with the female component to adjust a position of the first bone plate component with respect to the second bone plate component and wherein the male component is locked into place with respect to the female component by at least one bone screw inserted through the at least one hole of the second bone plate component causing compression between the first bone segment and the second bone segment to form a corrective construct.

2. The dynamic bone plate of claim 1 , wherein the male component comprises an elongated member receivable by the female component in a dovetail configuration.

3. The dynamic bone plate of claim 1 , wherein the female component comprises a dovetail receptacle configured for receiving the male component in a dovetail configuration.

4. The dynamic bone plate of claim 1 , wherein the male component and the female component, when mated, fit telescopically.

5. The dynamic bone plate of claim 1 , wherein tightening of a bone screw inserted through a hole of the at least one hole of the second bone plate component, causes a head of the bone screw to impinge on one edge of the male component mated with the female component and lock the male component in place within the female component.

6. The dynamic bone plate of claim 1 , wherein tightening of a secondary locking bone screw inserted through a hole of the at least one hole of the second bone plate component, causes the male component to lock into place within the female component by interference.

7. The dynamic bone plate of claim 6 , wherein when the secondary locking bone screw is not fully screwed through the hole, the male component is capable of sliding within the female component.

8. The dynamic bone plate of claim 1 , wherein the bone screws each comprise at least one thread.

9. The dynamic bone plate of claim 1 , wherein the bone screws are each dual thread screws.

10. The dynamic bone plate of claim 9 , wherein the dual thread screws each comprise a bone thread and a machine thread, wherein the bone thread is configured for attaching to bone, and the machine thread is configured for attaching to portions of the dynamic bone plate.

11. The dynamic bone plate of claim 1 , wherein the bone screws are screwed through the at least one holes using an external tool.

12. A dynamic plate, comprising:

a first plate component, comprising:

at least one hole configured for receiving screws for attachment to a first body segment; and

a male component;

a second plate component, comprising:

at least one hole configured for receiving screws for attachment to a second body segment; and

a female component configured for mating with the male component of the first plate component;

wherein the at least one hole of the second plate component overlaps with a side portion of the female component;

wherein the male component is adjustable after mating with the female component to adjust a position of the first plate component with respect to the second plate component and wherein the male component is locked into place with respect to the female component by at least one screw inserted through the at least one hole of the second plate component causing compression between the first body segment and the second body segment to form a corrective construct.

13. The dynamic plate of claim 12 , wherein the male component comprises an elongated member receivable by the female component in a dovetail configuration.

14. The dynamic plate of claim 12 , wherein the female component comprises a dovetail receptacle configured for receiving the male component in a dovetail configuration.

15. The dynamic plate of claim 12 , wherein the male component and the female component, when mated, fit telescopically.

16. The dynamic plate of claim 12 , wherein tightening of a screw inserted through a hole of the at least one hole of the second plate component, causes a head of the screw to impinge on a side of the male component mated with the female component and lock the male component in place within the female component.

17. The dynamic plate of claim 12 , wherein tightening of a secondary locking screw inserted through a hole of the at least one hole of the second plate component, causes the male component to lock into place within the female component by interference.

18. The dynamic plate of claim 17 , wherein when the secondary locking bone screw is not fully screwed through the hole, the male component is capable of sliding within the female component.

19. The dynamic plate of claim 12 , wherein the screws each comprise at least one thread.

20. The dynamic plate of claim 12 , wherein the screws are each dual thread screws.

21. The dynamic plate of claim 12 , wherein the screws are screwed through the at least one holes using an external tool.
