Abstract

A system, including methods, apparatus, components, and kits, for guiding a hole-forming tool and/or a fastener through a bone and then to a bone-repair device that is connected to the bone. In some embodiments, the system may include a guide device including (1) a coupling portion configured to be connected to the bone-repair device adjacent a first surface of a bone; and (2) a guide portion connected to the coupling portion and configured to be disposed adjacent a second surface of the bone that generally opposes the first surface on the bone. The guide portion is configured to guide the at least one hole-forming tool and fastener into the bone and then to a predefined position of the bone-repair device.

Claims

1. A system for bone fixation, comprising:

a bone plate structured to be secured to a bone such that the bone plate covers an exterior surface region of the bone, the bone, plate including a connective feature; and

a guide device including a guide portion and being structured to attach to the bone plate and to extend around the bone from the bone plate such that the guide portion opposes the bone plate across the bone and defines a guide axis for the connective feature of the bone plate.

2. The system of claim 1, wherein the bone plate includes an inner surface that faces the bone and an outer surface that opposes the inner surface, and wherein the guide portion is disposed closer to the inner surface than the outer surface.

3. The system of claim 1, wherein the connective feature is a threaded opening.

4. The system of claim 3, the threaded opening being a plurality of threaded openings included in the bone plate, wherein the guide portion is configured to guide fasteners through the bone and then to each of the threaded openings.

5. The system of claim 1, wherein the guide portion includes a frame and a guide element coupled movably to the frame, and wherein the guide element defines the guide axis.

6. The system of claim 5, wherein the guide element is movable parallel to the guide axis.

7. The system of claim 6, wherein the guide element includes indicia configured to measure a distance along the guide axis, and wherein the distance corresponds to a spacing of the bone plate from the guide element.

8. The system of claim 5, wherein the bone plate includes a plurality of predefined positions, and wherein the guide element is movable to define guide axes intersecting each of the predefined positions.

9. The system of claim 5, wherein the guide portion includes a detent mechanism configured to restrict movement of the guide element.

10. The system of claim 9, wherein the detent mechanism is configured to permit movement of the guide element toward the bone and to restrict movement of the guide element away from the bone.

11. The system of claim 9, wherein the detent mechanism is configured to be releasable manually without tools.

12. The system of claim 1, wherein the guide portion is configured to be movable into engagement with the bone so that the bone is pushed toward the bone plate.

13. The system of claim 1, wherein the guide portion includes a removable cannula defining the guide axis.

14. The system of claim 1, wherein the bone is a radius bone, and wherein the bone plate is configured to be connected adjacent a distal volar surface of the radius bone.

15. The system of claim 1, wherein the bone plate and the guide device are configured in correspondence for use on a left side or a right side of a body, but not both.

16. The system of claim 1, wherein the guide device extends only to an opposing side of the bone from the bone plate when the bone plate is secured to bone and the guide device is attached to the bone plate.

17. The system of claim 1, wherein the guide device extends about half way around the bone from the bone plate when the bone plate is secured to bone and the guide device is attached to the bone plate.
