Abstract
A method of performing an osteotomy including the steps of: providing a guide assembly; placing the guide assembly in operative relationship to a bone to be cut so that the guide assembly defines first and second guide edges that are in fixed relationship to each other to each guide movement of a cutting tool; guiding the cutting tool along each of the first and second guide edges to produce first and second cut lines in the bone to facilitate 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.
Claims23
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.
A method of performing an osteotomy, the method comprising the steps of:
- providing a base assembly;
- mounting the base assembly to a bone to be cut;
- providing a guide assembly;
- connecting the base assembly to the guide assembly,
- the base assembly and guide assembly together making up a first subassembly;
- placing the guide assembly in operative relationship to a bone to be cut so that the guide assembly defines first and second guide edges that are in fixed relationship to each other to each guide movement of a cutting tool;
- guiding the cutting tool along each of the first and second guide edges to produce first and second cut lines in the bone to facilitate 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;
- changing the width of the gap to be less than the first width;
- and
- directing a fixation component through the first and second bone surfaces using the first subassembly as a guide to thereby urge the first and second surfaces either against or adjacent to each other into a final desired relationship.
