Patent ID: 7674268

Claim:
A guide for cutting bone comprising: an anterior portion; a posterior portion including a first posterior flange and a second posterior flange; a distal portion between the anterior portion and the posterior portion, the distal portion including: a distal surface; a first guiding side; a second guiding side spaced apart from the first guiding side; and a plurality of cutting surfaces defined by each of the first guiding side and the second guiding side at an acute angle relative to the distal surface of the first and second guiding sides operable to guide a cutting device to the bone to form chamfer cuts in the bone; a box-cut shaped opening defined by the anterior portion, the first guiding side, the second guiding side, the first posterior flange, and the second posterior flange; a U-shaped raised rim that extends above an anterior portion of the box-cut shaped opening; a cutting tool coupled to the guide, the cutting tool having a longitudinal axis, the cutting tool rotatable about the longitudinal axis, the cutting tool pivotable within the box-cut shaped opening between the posterior portion and the raised rim at the anterior portion of the guide for forming a box cut in the bone; and a cylindrical rod extending between the first posterior flange and the second posterior flange, the rod coupled to an end of the cutting tool, the cutting tool selectively movable to a plurality of positions along the rod.
