Devices and methods for creating wedge-shaped recesses

A method of creating a wedge-shaped recess in a bone, the method comprising:

• creating a cylindrical recess within a bone, the cylindrical recess comprising cylindrically-shaped side walls and a bottom surface, wherein the cylindrical recess comprises a longitudinal axis;
• positioning a tool within the cylindrical recess, wherein a distal end of the tool comprises a tapered end, the tapered end of the tool being sized and configured to be placed within the cylindrical recess;
• and
• radially expanding an articulating cutter of the tool and rotating the tool to remove additional bone along the cylindrical side walls and to create a wedge-shaped recess;
• wherein the articulating cutter is expanded radially outwardly at an angle relative to the longitudinal axis;
• and
• wherein, after the wedge-shaped recess is formed, a diameter of the bottom surface of the wedge-shaped recess is larger than a diameter of a surface opening of the wedge-shaped recess.
