Paragraph Number

390

In the illustrated embodiment, the positioning guide 2300 serves to reduce the osteotomy and bring two bone fragments together for fixation and eventual fusion. Accordingly, the bone engagement surface 2310 can be configured to account for a portion of each of the bone fragments (e.g., posterior bone fragment 2114 and anterior bone fragment 2116) after one or more of these bone fragments has been translated and/or rotated to a position below the positioning guide 2300. Advantageously, in certain embodiments, the bone engagement surface 2310 can be defined, at least in part, based a lateral surface of a one or more bone models of bones involved in a surgical procedure. In addition, the bone engagement surface 2310 can be defined, at least in part, based on a planned reduced position of a posterior bone fragment 2114 and/or an anterior bone fragment 2116. The planned reduced position may represent a desired final position of the bone fragment prior to fixation. Advantageously, the bone engagement surface 2310 is configured to resemble, substantially resemble, and/or match the surface of the bone fragments in this condition. In certain embodiments, the bone engagement surface 2310 may engage the lateral surface of the bone fragments such that a surgeon can “feel” the positioning guide 2300 register into place and “feel” that the positioning guide 2300 is in the position planned before the surgical procedure.
