positioning a targeting guide adjacent to an outer surface of a surgical site, wherein the targeting guide comprises a handle extending substantially along a longitudinal axis and a flat head positioned at a distal end of the handle, wherein the longitudinal handle defines at least one burr hole extending from a first side of the handle to a second side of the handle and the flat head comprises a plurality of sections each defining a plurality of guide holes that extend from a first side of the flat head to the second side, and wherein the targeting guide is slidably coupled to the burr by inserting the burr into the surgical site;
inserting one or more k-wires into at least one bone at the surgical site, wherein the one or more k-wires are inserted through any of the plurality of guide holes formed in the flat head of the targeting guide;
removing the targeting guide and the burr from the surgical site;
cutting a bone at the surgical site, wherein the cut separates the bone into a first bone portion and a second bone portion;
inserting an elevator between the first bone portion and the second bone portion at the surgical site, wherein the elevator comprises a body defining a first inner cavity sized and configured to receive at least one bone and a displacement tip extending from a distal portion of the body, the displacement tip having a predetermined radius of curvature, wherein the displacement tip is sized and configured to be inserted between the first bone portion and the second bone portion; and
