Osteotomy fixation device and related systems and methods
An all-in-one osteotomy fixation device, along with various related components, systems, and methods. The various embodiments include a device body, a bone attachment structure, a removable slot body, and a movable cutting guide moveably attached to the body via a guide coupling structure. The various methods include using any single device embodiment herein to perform all of the steps of the osteotomy procedure.
1. A method of performing an osteotomy, the method comprising:
positioning an osteotomy device adjacent to a target bone, the osteotomy device comprising:
(a) a device body comprising:
(i) a bone attachment structure; and
(ii) a guide coupling structure comprising a rod rotatably associated with the coupling structure;
(b) a movable cutting guide threadably coupled to the rod; and
(c) a slot body removably attachable to the device body, wherein the slot body comprises a transverse slot defined within the slot body;
inserting a first anchoring pin through the transverse slot and into the target bone;
inserting a second anchoring pin through an opening defined in the bone attachment structure and into the target bone;
making a desired cut in the target bone with a saw blade positioned against the movable cutting guide, resulting in a base bone and a cut bone;
inserting a transposition mechanism through the movable cutting guide and into the cut bone;
urging the cut bone distally from the base bone by rotating the rod associated with the coupling structure;
urging the cut bone laterally by actuating the transposition mechanism;
urging the cut bone proximally into contact with the base bone by rotating the rod associated with the coupling structure;
removing the slot body from the device body; and
attaching a fixation plate to the cut bone and the base bone.
2. The method of claim 1 , wherein the movable cutting guide comprises a transposition mechanism threadably coupled thereto, wherein the transposition mechanism comprises a rotatable elongate body and a distal plate attached to a distal end of the rotatable elongate body.
3. The method of claim 2 , wherein the distal plate is a rotatable circular plate.
4. The method of claim 2 , wherein the rotatable elongate body is a threaded rotatable elongate body disposed through a threaded guide lumen defined in the movable cutting guide.
5. The method of claim 1 , wherein the movable cutting guide comprises a proximal guide edge.
6. The method of claim 1 , wherein the moveable cutting guide comprises an attachment body, wherein the attachment body comprises a threaded attachment lumen.
7. The method of claim 6 , wherein the rod comprises a threaded rod disposed within and threadably coupled with the threaded attachment lumen.
8. The method of claim 1 , wherein the movable cutting guide comprises:
(a) a first opening defined in the movable cutting guide, the first opening comprising a threaded opening configured to receive a transposition mechanism threadably coupled therein, wherein the transposition mechanism comprises a threaded rotatable elongate body and a distal plate attached to a distal end of the rotatable elongate body; and
(b) a second opening defined in the movable cutting guide, the second opening configured to receive an attachment pin.
9. The method of claim 1 , wherein the bone attachment structure comprises at least two fixation screw openings defined therein, wherein the bone attachment structure has a curved face configured to be contactable with the target bone.
10. The method of claim 1 , wherein the moveable cutting guide is moveable along a path substantially parallel with a length of the target bone.
11. The method of claim 1 , wherein the moveable cutting guide comprises a transposition rod threadably coupled to the moveable guide, wherein the transposition rod comprises a distal plate attached to a distal end of the transposition rod, wherein rotation of the transposition rod causes transverse movement of the transposition rod in relation to a longitudinal axis of the target bone.
