1. A method for correcting a bunion present in a patient's foot, the method comprising:
obtaining a first bone model of a cuneiform of the patient's foot;
obtaining a second bone model of a metatarsus of the patient's foot;
virtually repositioning the second bone model relative to the first bone model to simulate
reorientation of the metatarsus relative to the cuneiform to correct the bunion; and
using at least the first bone model relative to the repositioned second bone model to generate a cutting guide model defining:
a first bone engagement surface shaped to match a first contour on the cuneiform;
a second bone engagement surface shaped to match a second contour of the metatarsus; and
a first guide feature that, with the first bone engagement surface overlying the first contour, is positioned to guide resection of at least one of the cuneiform and the metatarsus as part of a bunion correction osteotomy for correcting the bunion.
