Minimally invasive displacement osteotomy system and method
A cutting guide includes a body extending between an upper surface and a lower surface and defined by a perimeter. The cutting guide further includes a guide foot having a contact surface. A guide element is pivotably coupled to the body. A handle extends from a first end to a second end. The first end is configured to be coupled to the body.
1. A cutting guide comprising:
a body extending between an upper surface and a lower surface and defined by a perimeter and a guide foot having a contact surface;
a guide element pivotably coupled to the guide foot defining an open ended channel sized to receive a cutting instrument to thereby form an osteotomy in a bone when the cutting instrument is pivoted about and through a pivot point, through a plane parallel to the upper surface, with the guide element while engaging bone; and
a handle comprising a body extending from a first end to a second end, wherein a first end is configured to be coupled to the body.
2. The cutting guide of claim 1 , wherein the handle is releasably coupled to the body.
3. The cutting guide of claim 2 , wherein the body comprises a coupling feature configured to releasably couple the handle to the body.
4. The system of claim 3 , wherein the handle comprises a first coupling feature and the body of the cutting guide defines a second coupling feature, and wherein the first coupling feature and the second coupling feature are configured to releasably couple the handle to the body of the cutting guide.
5. The system of claim 4 , wherein the first coupling feature comprises a first thread and the second coupling feature comprises a second thread configured to engage the first thread.
6. The cutting guide of claim 1 , wherein the guide element comprises a guide element body extending along a longitudinal axis and the open ended channel is substantially along the longitudinal axis, wherein the longitudinal axis extends at a predetermined angle with respect to the upper surface of the body.
7. The cutting guide of claim 6 , wherein the channel is sized and configured to receive the cutting element therethrough, wherein the guide element is configured to pivot with respect to the body such that the cutting element traverses a plane having a predetermined angle with respect to the upper guide surface.
8. The cutting guide of claim 7 , wherein the cutting element includes a first portion having a first diameter sized and configured to be received within the channel of the guide element and a second portion having a second diameter, wherein the second diameter is less than the first diameter.
9. The cutting guide of claim 4 , wherein the guide element comprises a projection extending from a first surface of the guide element body, wherein the projection is sized and configured to be received within a hole defined in the body of the cutting guide, and wherein the cutting guide body is configured to pivot about a pivot point defined by the hole.
10. The cutting guide of claim 1 , wherein the body defines at least one fixation hole sized and configured to receive a fixation element therethrough.
