[0051] Open wedge high tibiotomy overview

[0052] Looking first at Figures 1-3, a knee joint 5 is shown on which an open cuneiform osteotomy will be performed. Knee joint 5 generally includes tibia 10 and femur 15 . According to the present invention, the wedge-shaped opening 25 is configured to accommodate the bone by first making an incision 20 ( FIG. 1 ) in the upper tibia, and then manipulating the lower portion of the tibia to open the wedge-shaped opening 25 ( FIG. 2 ) in the bone. The way loads are transferred from the femur to the tibia, enabling an open cuneiform osteotomy. Cutouts 20 and wedge-shaped openings 25 can be formed in a variety of ways well known in the art.

[0053] Among other things, the present invention provides new and improved methods and apparatus for forming cutouts 20 and wedge-shaped openings 25, as will be discussed in greater detail below.

[0054] Once the desired wedge-shaped opening 25 has been formed in the tibia 10 in order to reconf...

Abstract

An apparatus for performing an open wedge high tibiotomy comprising: a cutting apparatus for forming an osteotomy incision in the tibia, the cutting apparatus comprising: identifying a cutting plane through the tibia and terminating Targeting device of the borderline of the cut along the cutting plane, wherein the borderline is positioned inside the tibia, parallel to the anterior-posterior slope of the tibia and parallel to the sagittal plane of the patient. A method for performing an open wedge high tibiotomy, the method comprising: positioning a targeting device for identifying a cutting plane through the tibia and a borderline for terminating cuts made along the cutting plane, wherein the borderline is positioned at Inside the tibia, parallel to the anterior-posterior slope of the tibia and parallel to the patient's sagittal plane; cut the bone along the cutting plane, with the cut terminating at the borderline; move the bone on each side of the cut apart to create a wedge-shaped opening in the bone; and stable bone.
