1. A bi-planar instrument for a bone cutting and joint realignment procedure, the instrument comprising:
a spacer body configured to be inserted into a joint space between a metatarsal and an opposed cuneiform of a foot, wherein the spacer body has a first surface configured to contact the metatarsal and a second surface configured to contact the opposed cuneiform, the spacer body defining a length configured to be inserted into the joint space, a thickness defined between the first surface and the second surface configured to extend between the metatarsal and the opposed cuneiform, and a width configured to extend in a medial to lateral direction across at least a portion of the joint space, the width being greater than the thickness; and
a fulcrum body coupled to the spacer body, the fulcrum body being configured to be inserted in an intermetatarsal space between the metatarsal and an adjacent metatarsal such that, when the spacer body is inserted into the joint space and the fulcrum body is inserted into the intermetatarsal space, the bi-planar instrument is configured to extend around a proximal-lateral portion of the metatarsal, and wherein the fulcrum body defines a length configured to be inserted into the intermetatarsal space, a thickness configured to extend between the metatarsal and the adjacent metatarsal, and a width configured to extend in a proximal to a distal direction along the foot.
