Abstract

A dynamic bone plate and method of bone compression are disclosed. The dynamic bone plate comprises a first bone plate component including at least one hole for receiving screws for attachment to a first bone segment and a male component and a second bone plate component including at least one hole for receiving screws for attachment to a second bone segment and a female component for mating with the male 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 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 bone plate component causing compression between the first and second bone segments to form a corrective construct.

Claims (32)

1. A dynamic bone plate, comprising:

a first bone plate component having a top surface and a bottom surface, comprising:

at least one hole extending through the first bone plate component and configured for receiving bone screws for attachment to a first bone segment, the at least one hole being recessed in the top surface of the first bone plate;

a male component projecting from the top surface of the first bone plate component; and

a base portion with a length and a width larger than a length and a width of the male component;

a second bone plate component having a top surface and a bottom surface, comprising:

at least one hole extending through the second bone plate component and configured for receiving bone screws for attachment to a second bone segment, the at least one hole being recessed in the top surface of the second bone plate; and

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

wherein the female component forms an opening extending through an interior portion of the second bone plate component;

wherein the male component is moveable within the opening in the interior portion of the second bone plate component after mating with the female component to adjust a position of the first bone plate component with respect to the second bone plate component, wherein the base portion is juxtaposed to the bottom surface of the second bone plate component when 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 second plate component comprises a plurality of female components, each female component configured for mating with a corresponding male component.

3. The dynamic bone plate of claim 1 , wherein the bone screws are inserted through the at least one hole using an external tool and wherein the external tool comprises at least two pins.

4. The dynamic bone plate of claim 1 , wherein the male component connectively engages the female component.

5. The dynamic bone plate of claim 1 , wherein the first bone plate component comprises a recessed hole configured to receive a bone screw that secures both the first bone plate component and the second bone plate component together after the male component has been joined with the female component.

6. The dynamic bone plate of claim 1 , wherein the at least one hole in the first bone plate comprises:

a shaft opening portion that extends from the top surface through the plate to the bottom surface; and

a head opening portion that is recessed in the top surface of the plate, wherein the head opening portion extends to an outer edge of the male component and is configured to receive a head of a bone fastener, and wherein the head of the bone fastener engages the top surface of both the first bone plate component and the second bone plate component.

7. The dynamic bone plate of claim 1 , wherein the opening of the female component of the second bone plate component includes two interior sidewalls and the male component includes two exterior sidewalls; and

wherein the two exterior sidewalls of the male component slidingly engage the two interior sidewalls of the female component.

8. A dynamic plate, comprising:

at least two screws;

a first plate component, comprising:

a male component extending from at least a portion of the first plate component; and

at least one hole extending through the male component and the first plate component and configured for receiving at least one of the at least two screws for attachment to a first body segment, and wherein the at least one hole is positioned for a portion of the hole to overlap with an edge of the male component;

a second plate component, comprising:

a female component extending through at least a portion of the second plate component and configured for mating with the male component of the first plate component; and

at least one hole extending through the second plate component and configured for receiving at least one of the at least two screws for attachment to a second body segment;

wherein the male component is adjustable after mating with the female component to allow movement between the first plate component and the second plate component, and wherein the male component is locked into place with respect to the female component by at least one of the at least two screws 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; and

wherein the at least one hole of the first plate component is configured to receive one screw of the at least two screws and a head of the one screw engages the portion of the hole that overlaps with the edge of the male component and a portion of the second plate component.

9. The dynamic plate of claim 8 , wherein the screws are inserted through the at least one hole using an external tool having at least two pins.

10. The dynamic plate of claim 8 , wherein the male component is coupled to the female component.

11. The dynamic plate of claim 8 , wherein the first plate component comprises a recessed hole configured to receive a screw that holds both the first plate component and the second plate component together after the male component has mated with the female component.
