An instrument having a proximal portion, that includes a guide having at least one opening, the at least one opening having at least one trajectory. The instrument includes a distal portion that has an engagement mechanism that engages with a first segment of a first metatarsal, and an adjustment mechanism that engages with a second segment of a first metatarsal. A surgical method is disclosed with the steps of: coupling the instrument to the foot of a patient; positioning the instrument so a pair of rails are substantially parallel to the first metatarsal; manipulating a locking mechanism; coupling the distal portion of the instrument with a proximal portion segment of the first metatarsal; coupling an angel wing with the instrument; correcting the deformity of the first metatarsal; targeting the implantation of at least one implant and implanting the at least one implant into the first metatarsal.
