Abstract
Systems and methods for performing an osteotomy are presented. Examples include forming a fusion osteotomy at a metatarsocuneiform joint of the first ray of a human foot.
Claims15
An osteotomy guide comprising:
- a guide body defining a joint alignment slot that facilitates alignment of the osteotomy guide with a metatarsocuneiform joint via insertion of an element into the metatarsocuneiform joint;
- a feeler gauge sized to be inserted into the joint alignment slot, such that the feeler gauge is configured to align the joint alignment slot with the metatarsocuneiform joint;
- a first guide slot of the guide body, spaced apart from the joint alignment slot and parallel to the joint alignment slot such that, with the osteotomy guide positioned to align the joint alignment slot with the metatarsocuneiform joint, the first guide slot is positioned to guide a first cutter to cut a metatarsus of the metatarsocuneiform joint, to remove part of the metatarsus;
- and
- at least one indexing feature sized and shaped to abut a diaphysis of the metatarsus when the joint alignment slot is aligned with the metatarsocuneiform joint,
- wherein the at least one indexing feature is configured to be offset from the guide body, and
- wherein the osteotomy guide is configured to be fixed to at least one of the metatarsus and the cuneiform with one or more fixation elements.
