Abstract:
1. A method of performing an osteotomy, the method comprising the steps of: providing a guide assembly; providing a base assembly; fixedly mounting the base assembly to abut against an exposed surface of a bone to be cut; connecting the guide assembly to the base assembly to thereby place the guide assembly in operative relationship to the bone so that the guide assembly defines first and second guide edges that are fixed in operative, non-parallel relationship to each other to each guide movement of a cutting tool; guiding the cutting tool along each of the first and second non-parallel guide edges without moving the guide assembly relative to the bone to produce first and second cut lines in the bone that allow separation of a fragment of the bone from between first and second bone surfaces formed respectively at the first and second cut lines; separating the bone fragment so that a gap with a first width is formed between the first and second bone surfaces; and changing the width of the gap to be less than the first width.
