Abstract

Claims (46)

1 . A tibial osteotomy system, comprising:

a base plate comprising a first end and a second end;

a measuring arm coupled with and extending from the first end of the base plate; and

a cut guide coupled with and extending from the second end of the base plate, wherein the cut guide is translatable relative to the base plate and the measuring arm;

wherein the measuring arm is coupled with the first end of the base plate by a first screw and the cut guide is coupled with the second end of the base plate by a second screw; and

wherein the first and second screws each have a bore extending through a length of the screws along a central axis, the bores being configured to receive a stabilization element.

2 . The tibial osteotomy system of claim 1 , wherein the measuring arm comprises a curved geometry.

3 . The tibial osteotomy system of claim 2 , wherein the measuring arm further comprises:

a head portion comprising an aperture configured to fixedly couple with the first end of the base plate; and

an arm portion extending from the head portion comprising a guide portion.

4 . The tibial osteotomy system of claim 1 , wherein the cut guide is pivotably coupled with the second end of the base plate.

5 . The tibial osteotomy system of claim 4 , wherein the cut guide further comprises:

a head portion comprising an aperture configured to pivotable couple with the second end of the base plate; and

a body extending from the head portion comprising a first arm and a second arm, wherein the first arm and the second arm define a slot.

6 . The tibial osteotomy system of claim 5 , wherein the cut guide further comprises:

a measurement flag releasably couplable with the slot such that pivoting of the cut guide relative to the measuring arm positions the measurement flag adjacent to a guide portion of the measuring arm.

7 . The tibial osteotomy system of claim 5 , wherein the slot is configured to accommodate a blade of a cutting tool.

8 . The tibial osteotomy system of claim 5 , wherein the cut guide further comprises:

a protrusion extending from the body of the cut guide and having at least one aperture, wherein the aperture of the protrusion is configured to receive a stabilization element.

9 . The tibial osteotomy system of claim 1 , wherein the base plate comprises a body portion disposed between the first end and the second end, wherein a bottom surface of the base plate is configured to interface with an anterior surface of a tibia.

10 . The tibial osteotomy system of claim 9 , wherein a body portion of the base plate comprises a pair of apertures configured to receive a pair of stabilization elements, wherein the stabilization elements couple the base plate to the tibia.

11 . The tibial osteotomy system of claim 1 , wherein the first and second screws are configured the same.

12 . A tibial osteotomy system, comprising:

a base plate configured to interface with a tibia, wherein the base plate comprises:

a body comprising a first pair of apertures configured to receive a first pair of stabilization elements;

a first end comprising a first aperture; and

a second end comprising a second aperture, wherein the first end is opposite the second end;

a measuring arm fixedly coupled to the first end of the base plate via the first aperture and further comprising a third aperture, wherein the third aperture and the first aperture align to receive a first screw therein; and

a cut guide pivotably coupled with the second end of the base plate via the second aperture and a fourth aperture, the fourth aperture and second aperture are aligned to receive a second screw therein, wherein the cut guide further comprises:

a slot;

a measurement flag releasably couplable within the slot; and

a protrusion comprising a fifth aperture, wherein the fifth aperture is configured to receive a second stabilization element therethrough.

13 . The tibial osteotomy system of claim 12 , wherein the first screw and the second screw each comprise a bore configured concentrically about a central axis, the bores configured to receive a second pair of stabilization elements.

14 . The tibial osteotomy system of claim 13 , wherein the second pair of stabilization elements are K-wires.

15 . The tibial osteotomy system of claim 12 , wherein the first pair of stabilization elements are olive wires.

16 . The tibial osteotomy system of claim 12 , wherein the measuring arm comprises a guide portion, the guide portion comprising incremental measurement markings.

17 . The tibial osteotomy system of claim 12 , wherein a measurement flag is coupled within the slot such that pivoting the cut guide positions the measurement flag adjacent the incremental measurement markings.

18 . A method of preparing a tibia for a tibial osteotomy, the method comprising:

providing a tibial osteotomy system, the system comprising:

a base plate;

a measuring arm fixedly coupled with the base plate; and

a cut guide pivotably coupled with the base plate and comprising a measurement flag releasably coupled within a slot;

coupling the base plate with the tibia;

pivoting the cut guide such that the measurement flag of the cut guide is positioned adjacent the measuring arm;

removing the measurement flag from the slot; and

positioning a cutting tool such that a blade of the cutting tool is disposed within the slot of the cut guide and adjacent the tibia.
