Bi-planar instrument for bone cutting and joint realignment procedure

A method for correcting an alignment of a bone in a foot and preparing bones for fusion, the method comprising:

• inserting a unitary instrument comprising a spacer body connected to a fulcrum body between bones of a foot by inserting the spacer body into a joint space between a metatarsal and an opposed cuneiform and simultaneously inserting the fulcrum body between the metatarsal and an adjacent metatarsal,
• preparing an end of the metatarsal using a bone preparation guide aligned with the spacer body to guide a bone preparation instrument;
• preparing an end of the opposed cuneiform using the bone preparation guide to guide the bone preparation instrument;
• and
• moving the metatarsal relative to the adjacent metatarsal in at least a transverse plane, thereby pivoting the metatarsal about the fulcrum body and reducing an intermetatarsal angle between the metatarsal and the adjacent metatarsal.
