Abstract

The present invention discloses an alignment guide apparatus, system, and method. The alignment guide apparatus includes a body, a fixation insert, a guide pin, and a screw. The body may include an arm with a first end and a second end, an attachment portion at the first end, and an alignment portion at the second end. The fixation insert may be configured to pass through the attachment portion and the guide pin may be configured to pass through the alignment portion. The screw may be configured to engage the guide pin. The alignment system may include a bone plate, an alignment guide, a screw, at least one first fastener, and at least one second fastener. A method for moving a joint is also disclosed.

First claim

Having thus described the preferred embodiments, the invention is now claimed to be:

1. A bone plate alignment guide apparatus, comprising:
a body, the body comprising:
an arm with a first end and a second end;
an attachment portion comprising:
a through hole; and

an alignment portion comprising:
at least one through hole;

a fixation insert rotatably coupled to the attachment portion, wherein the fixation insert includes an engagement portion for engaging a portion of a bone plate;
a guide pin configured to pass through the at least one through hole of the alignment portion; and
a screw configured to receive the guide pin;
wherein the arm is configured to position an axis of the through hole of the attachment portion generally perpendicular to an axis of the at least one through hole of the alignment portion, and
wherein the screw is offset from the bone plate.

2. The alignment guide apparatus of claim 1 , further comprising a drill bit configured to be inserted over the guide pin.

3. The alignment guide apparatus of claim 1 , wherein the at least one through hole of the alignment portion comprises a plurality of through holes.

4. The alignment guide apparatus of claim 3 , wherein the plurality of through holes may be at least one of straight and angled relative to the alignment portion.

5. The alignment guide apparatus of claim 3 , wherein the plurality of through holes comprises three holes, the three holes including a central hole and two holes positioned linearly with the central hole and defining a right hole and a left hole.

6. The alignment guide apparatus of claim 5 , wherein at least one of the right hole and the left hole are angled towards the central hole.

7. The alignment guide apparatus of claim 5 , wherein the right hole and left hole are angled towards the central hole, wherein a central axis for each of the right hole and the left hole intersect a central axis of the central hole at a distance from the alignment portion.

8. The alignment guide apparatus of claim 1 , wherein the fixation insert comprises:
a knob portion; and
a shaft portion extending away from the knob portion.

9. The alignment guide apparatus of claim 8 , wherein the shaft portion comprises an alignment portion and a threaded section for engaging the at least one opening of the bone plate.

10. The alignment guide apparatus of claim 1 , further comprising:
a guide pin tissue protector, wherein the guide pin tissue protector comprises:
a first end and a second end:
a shaft portion having a handle portion connected to the first end;
a tip proximate to the second end; and
a hole extending from the first end to the second end.

11. The alignment guide apparatus of claim 1 , wherein the screw has a first end and a second end, the screw comprising:
a head portion at the first end;
a shaft portion extending away from the head portion to the second end, wherein the shaft portion comprises a smooth portion and a threaded portion; and
a through hole extending from the first end to the second end.

12. A bone plate alignment system, comprising:
a bone plate, comprising:
at least one through hole, wherein at least one of the at least one through holes is a compression slot;

a bone plate alignment guide, comprising:
a body, comprising:
an arm with a first end and a second end;
an attachment portion; and
an alignment portion;

a fixation insert rotatably coupled to the attachment portion, wherein the fixation insert couples with the bone plate; and
a guide wire configured to pass through the alignment portion;

a screw;
at least one first fastener for insertion through at least one of the at least one through holes of the bone plate and into a first portion of bone; and
at least one second fastener for insertion through at least one of the at least one through holes of the bone plate and into a second portion of bone, and
wherein the attachment portion is positioned superior to the alignment portion in a direction extending from a bottom bone contacting surface to a top surface of the bone plate when the fixation insert engages the bone plate.

13. The bone plate alignment system of claim 12 , wherein the screw is configured to engage the guide wire.

14. The bone plate alignment system of claim 12 , further comprising:
a drill configured to be inserted over the guide wire.

15. The bone plate alignment system of claim 12 , wherein the fixation insert couples with at least one of the at least one through holes of the bone plate.

16. The bone plate alignment system of claim 12 , wherein the screw has a first end and a second end and comprises:
a through hole extending from the first end to the second end, the through hole configured to receive the guide wire.

17. The bone plate alignment system of claim 12 , wherein the bone plate further comprises:
a first end, a second end, and an intermediate portion connecting the first end and the second end of the bone plate, wherein each of the first and second ends comprise at least one of the at least one through holes.

18. A method for moving a joint of a patient, comprising:
preparing the joint;
obtaining a bone plate alignment guide apparatus, comprising:
a body, the body comprising:
an arm with a first end and a second end;
an attachment portion at the first end; and
an alignment portion at the second end;

a fixation insert rotatably coupled to the attachment portion;
a guide pin configured to pass through the alignment portion; and
a screw;

aligning the bone plate on the joint, wherein the bone plate comprises:
a plurality of through holes, wherein at least one of the plurality of through holes is a compression slot;

inserting at least one first temporary fixation pin to secure the bone plate to a first bone of the joint;
inserting at least one second temporary fixation pin to secure the bone plate to a second bone of the joint;
attaching the bone plate alignment guide apparatus to the bone plate in a desired position relative to the joint;
inserting the guide pin across the joint through the alignment portion of the body of the bone plate alignment guide apparatus;
inserting the screw;
securing the bone plate to the first bone and the second bone of the joint;
removing the bone plate alignment guide apparatus; and
closing an incision of the patient.

19. The method for moving a joint of claim 18 , wherein the screw is configured to engage the guide pin.
