252

A guide anchor is an anchor for a resection guide (described herein). The guide anchor serves to hold a resection guide in place during an osteotomy. In one embodiment, a guide anchor is strategically placed guide pins that pass through a resection guide and hold the resection guide securely to a bone of a patient for the osteotomy. A proximal resection guide anchor 954 is a guide anchor that is proximal during a surgical procedure. A distal resection guide anchor 956 is a guide anchor that is distal during a surgical procedure. In certain embodiments, a proximal resection guide anchor 954 may be deployed in a cuneiform and a distal resection guide anchor 956 may be deployed in a metatarsal. Advantageously, because the surgical procedure is preplanned using medical imaging of bones of a patient the same guide pins that serve as a proximal reference feature and those that serve as a distal reference feature can also serve as a proximal resection guide anchor 954 and a proximal alignment feature 944 and as a distal resection guide anchor 956 and a distal alignment feature 946. Those of skill in the art will appreciate that a reference feature can serve as an alignment feature or a resection guide anchor or both depending on the embodiment. Advantageously, the navigation guide 900 may identify where to position the first reference feature and the second reference feature for use for resection or cutting of one or more bones and for alignment and repositioning of bone fragments after the osteotomies.
