Claims20
An osteotomy system that facilitates performance of an osteotomy between a metatarsus and a cuneiform defining a metatarsocuneiform joint of a human foot, the osteotomy system comprising:
- an osteotomy guide comprising:
- a joint alignment feature that facilitates alignment of the osteotomy guide with the metatarsocuneiform joint via insertion of an element into the metatarsocuneiform joint;
- one or more fixation elements that facilitate fixation of the osteotomy guide to at least one of the metatarsus and the cuneiform;
- and
- a first guide feature, spaced apart from the joint alignment feature such that, with the osteotomy guide positioned to align the joint alignment feature with the metatarsocuneiform joint, the first guide feature is positioned to guide a first cutter to cut the metatarsus to remove part of the metatarsus.
An osteotomy system that facilitates performance of an osteotomy between a metatarsus and a cuneiform defining a metatarsocuneiform joint of a human foot, the osteotomy system comprising:
- an osteotomy guide comprising:
- a first guide feature positionable to guide a first cutter to cut the metatarsus to remove part of the metatarsus;
- and
- a second guide feature that, with first guide feature positioned to guide the first cutter to cut the metatarsus, is positioned to guide one of the first cutter and a second cutter to remove part of the cuneiform to create a gap between the metatarsus and the cuneiform;
- wherein the first guide feature and the second guide feature are on a one-piece guide body.
An osteotomy system that facilitates performance of an osteotomy between a metatarsus and a cuneiform defining a metatarsocuneiform joint of a human foot, the osteotomy system comprising:
- an osteotomy guide comprising:
- a first guide feature that is positionable to guide a first cutter to cut the metatarsus to remove part of the metatarsus;
- and
- a second guide feature that, with the first guide feature unobstructed and positioned to guide the first cutter to cut the metatarsus, is positioned to guide one of the first cutter and a second cutter to remove part of the cuneiform to create a gap between the metatarsus and the cuneiform.
