One surgical method includes coupling, to a cuneiform of a subject, a surgical apparatus for use in facilitating correction of a bunion and coupling the surgical apparatus to another bone of the subject. Another surgical method includes coupling a surgical apparatus to a cuneiform and metatarsal of a subject, coupling a cutting block for alignment at a joint between the cuneiform and the metatarsal, and performing a surgical procedure utilizing the surgical apparatus and the cutting block to correct a bunion. A further surgical method includes providing a surgical apparatus for use in facilitating correction of a bunion in a subject in which the surgical apparatus is configured to couple to a cuneiform and a metatarsal of the subject and performing a surgical procedure utilizing the surgical apparatus while the surgical apparatus is coupled to the cuneiform and the metatarsal. ## Claims ### Claim 1 A method, comprising: coupling, to a cuneiform of a subject, a surgical apparatus for use in facilitating correction of a bunion in the subject, wherein the cuneiform is a first bone of the subject; and coupling the surgical apparatus to a second bone of the subject; wherein the second bone comprises a metatarsal; using the surgical apparatus to rotate the metatarsal about its longitudinal axis to place the metatarsal in a rotated position; and using the surgical apparatus to lock the metatarsal in the rotated position. ### Claim 2 (depends on 1) The method of claim 1, further comprising: performing a surgical procedure to correct the bunion using the surgical apparatus. ### Claim 3 (depends on 1) The method of claim 1, further comprising using the surgical apparatus to correct an intermetatarsal angle of the metatarsal. ### Claim 4 (depends on 1) The method of claim 1, further comprising: using the surgical apparatus to distract a joint between the cuneiform and the metatarsal subsequent to the metatarsal being locked in the rotated position. ### Claim 5 (depends on 4) The method of claim 4, further comprising: using the surgical apparatus to compact the joint subsequent to the joint being distracted. ### Claim 6 (depends on 1) The method of claim 1, wherein: the surgical apparatus comprises an attachment body configured to couple the surgical apparatus to the cuneiform, the attachment body comprising one or more first apertures; and coupling the surgical apparatus to the cuneiform comprises inserting one or more first wires through the one or more first apertures of the attachment body and into the cuneiform. ### Claim 7 (depends on 6) The method of claim 6, wherein: the surgical apparatus further comprises a distraction body configured to couple the surgical apparatus to the metatarsal, the distraction body comprising one or more second apertures; and the method further comprises coupling the distraction body of the surgical apparatus to the metatarsal by inserting one or more second wires through the one or more second apertures and into the metatarsal. ### Claim 8 A method, comprising: coupling a surgical apparatus to a cuneiform and a metatarsal of a subject; coupling a cutting block for alignment at a joint between the cuneiform and the metatarsal of the subject; and performing a surgical procedure utilizing the surgical apparatus and the cutting block to correct a bunion in the subject; rotating, via a rotation guide of the surgical apparatus and a guide wire, the metatarsal about its longitudinal axis to place the metatarsal in a rotated position; and locking the metatarsal in the rotated position via the rotation guide and guide wire. ### Claim 9 (depends on 8) The method of claim 8, wherein performing the surgical procedure comprises: correcting, via an arm and an adjustment screw of the surgical apparatus, an intermetatarsal angle of the metatarsal. ### Claim 10 (depends on 8) The method of claim 8, wherein performing the surgical procedure further comprises: using the cutting block to facilitate surgically cutting the joint. ### Claim 11 (depends on 10) The method of claim 10, wherein performing the surgical procedure further comprises: distracting the joint subsequent to the joint being surgically cut; and removing excess bone from the joint. ### Claim 12 (depends on 11) The method of claim 11, wherein performing the surgical procedure further comprises: compacting the joint subsequent to the joint being distracted and removal of the excess bone. ### Claim 13 (depends on 12) The method of claim 12, wherein performing the surgical procedure further comprises: permanently fixating the joint subsequent to the joint being compacted. ### Claim 14 A method, comprising: providing a surgical apparatus for use in facilitating correction of a bunion in a subject, wherein the surgical apparatus is configured to couple to a cuneiform and a metatarsal of the subject; and performing a surgical procedure utilizing the surgical apparatus while the surgical apparatus is coupled to the cuneiform and the metatarsal of the subject; using the surgical apparatus to rotate the metatarsal about its longitudinal axis to place the metatarsal in a rotated position; and using the surgical apparatus to lock the metatarsal in the rotated position. ### Claim 15 (depends on 14) The method of claim 14, wherein: the surgical apparatus comprises an attachment body configured to couple the surgical apparatus to the cuneiform, the attachment body comprising one or more first apertures; and coupling the surgical apparatus to the cuneiform comprises inserting one or more first wires through the one or more first apertures of the attachment body and into the cuneiform. ### Claim 16 (depends on 15) The method of claim 15, wherein: the surgical apparatus further comprises a distraction body configured to couple the surgical apparatus to the metatarsal, the distraction body comprising one or more second apertures; and the method further comprises coupling the distraction body of the surgical apparatus to the metatarsal by inserting one or more second wires through the one or more second apertures and into the metatarsal. ### Claim 17 (depends on 16) The method of claim 16, wherein performing the surgical procedure comprises: correcting, via an arm and an adjustment screw of the surgical apparatus, an intermetatarsal angle of the metatarsal; distracting the joint subsequent to the metatarsal being rotated; compacting the joint subsequent to the joint being distracted; and permanently fixating the joint subsequent to the joint being compacted.
