Problems solved by technology

[0019] While both closed and open cuneidotomy provide substantial benefit to the patient, they are procedurally challenging for the surgeon
With respect to opening cuneiform osteotomy, among other things, it can be difficult to create a wedge-shaped opening in the bone with the necessary precision and with minimal damage to surrounding tissue

[0051] Open wedge high tibiotomy overview

[0052] look first Figure 1-3 , shows the knee joint 5 on which an open cuneiform osteotomy will be performed. Knee joint 5 generally includes tibia 10 and femur 15 . According to the present invention, by first forming incision 20 ( figure 1 ), and then manipulate the lower portion of the tibia to open a wedge-shaped opening 25 in the bone ( figure 2 ), so that the wedge-shaped opening 25 is configured to adjust the way the load is 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 reconfigure the tibia 10 into the...

Abstract

Apparatus for performing an open wedge, high tibial osteotomy, the apparatus comprising: cutting apparatus for forming an osteotomy cut in the tibia, the cutting apparatus comprising: targeting apparatus for identifying a cutting plane through the tibia and a boundary line for terminating a cut made along the cutting plane, wherein the boundary line is located within 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 tibial osteotomy, the method comprising: positioning targeting apparatus for identifying a cutting plane through the tibia and a boundary line for terminating a cut made along the cutting plane, wherein the boundary line is located within the tibia, parallel to the anterior-posterior slope of the tibia and parallel to the sagittal plane of the patient; cutting the bone along the cutting plane, with the cut terminating at the boundary line; moving the bone on eitherside of the cut apart so as to form the wedge-like opening in the bone; and stabilizing the bone.
