Patient-specific bridging plates
Disclosed herein are a bone plating system and a method for utilizing the same. The bone plating system may include first and second bone plates in contact with respective first and second bones, a cross-connector, a cutting guide and a targeter device. The cross-connector may have a first end and an opposite second extending along a longitudinal axis from the first bone plate to the second bone plate. The cutting guide may have an elongate body placed on one of the first or second bones. The targeter device may have a drill guide to align the cross-connector with the first and second bone plates. A method for fixing the bone plating system to the first and second bone may include using the targeter device.
1. A method of fixing a bone plating system to a first bone and a second bone with a third bone disposed between the first and second bones, the method comprising:
placing a bone contacting surface of a cutting guide having an elongate body on a surface of the first bone;
drilling a first hole through a slot in the cutting guide, the hole extending through the first and second bones;
placing a first bone plate on the first bone and a second bone plate on the second bone;
placing a first arm of a targeter device on the first bone plate and a second arm of the targeter device on the second bone plate;
drilling a second hole through the first hole using the first and second arms of the targeter device as a drill guide; and
securing a cross-connector through the second hole such that the first bone, second bone and third bone are secured by the first and second bone plates.
2. The method of claim 1 , wherein the first bone is at least one of a metatarsal bone, a medial cuneiform bone or a navicular bone.
3. The method of claim 1 , wherein the second bone is at least one of a cuboid bone or a calcaneus bone.
4. The method of claim 1 , wherein the third bone is at least one of intermediate cuneiform bone or a lateral cuneiform bone.
5. The method of claim 1 , further comprising resecting a first counterbore in the first bone and resecting a second counterbore in the second bone.
6. The method of claim 5 , further comprising placing a guidewire through the first hole.
7. The method of claim 6 , further comprising:
placing a drill column over the guidewire; and
ensuring that the first and second counterbores are aligned with an axis of the first hole.
8. The method of claim 5 , wherein the step of placing the first bone plate on the first bone comprises aligning a first fixation hole of the first bone plate with the first counterbore.
9. The method of claim 5 , wherein the step of placing the second bone plate on the second bone comprises aligning a collar of the second bone plate with the second counterbore.
10. The method of claim 1 , wherein the step of placing a first arm of the targeter device on the first bone plate and a second arm of the targeter device on the second bone plate comprises:
retracting the first and second arms of the targeter device away from one another;
aligning the first and second arms of the targeter device with an axis of the first hole; and
allowing the first and second arms of the targeter device to move toward one another, under a biasing force, to secure the first and second bone plates relative to one another.
11. The method of claim 10 , further comprising fastening the first bone plate to the first bone and fastening the second bone plate to the second bone prior to drilling the second hole.
12. The method of claim 1 , wherein the securing step comprises fastening the cross-connector between the first and second bone plates.
13. The method of claim 12 , further comprising:
introducing a biologic fluid through an inlet of the cross-connector having a channel extending in a length direction of the cross-connector and a plurality of apertures extending through an external surface of the cross-connector and in communication with the channel of the cross-connector.
