Claim 8:
9. A patient-specific opening validating tool for validating a wedge opening of a patient's bone, the patient's bone having a wedge opening defining a top interior surface and a bottom interior surface diverging from one another, the opening validating tool comprising:
a body having a handle end to facilitate manipulation of the tool and an operative end comprising:
a wedge element shaped and configured to fit snugly in the wedge opening in the patient's bone based on an expected shape thereof as determined according to a preoperative plan, the wedge element comprises a substantially planar top surface shaped to conform to a contour of the top interior surface of the patient's bone and a substantially planar bottom surface shaped to conform to a contour of the bottom interior surface of the patient's bone, the substantially planar top and bottom surfaces of the wedge element tapering towards one another to define a thicker end of the wedge element and a thinner free end of the wedge element; and
a tab element located between the handle end of the body and the wedge element adjacent to the thicker end of the wedge element, the substantially planar bottom and top surfaces of the wedge element tapering towards one another from the thicker end to the thinner free end, the tab element having a bone-contacting surface shaped and adapted to abut against and conform to exterior contours of the patient's bone when the wedge element is inserted in the wedge opening in a predetermined position and orientation to limit an insertion depth of the wedge element within the wedge opening and confirm that a configuration of the wedge opening matches the preoperative plan, and wherein the wedge element and the tab element are integrally formed together as a single piece.
