An osteotomy procedure may be performed to correct a misalignment of a bone, such as a bunion deformity. In some examples, the osteotomy procedure involves making a first crescentic-shaped cut transecting a first metatarsal, thereby forming a concave-shaped end and a convex-shaped end on opposed bone portions. The method further involves making a second crescentic-shaped cut across the concave-shaped end of one bone portion and thereafter moving the bone portions relative to each other in multiple planes to correct an anatomical misalignment.
