A device for treating an angular bone deformity, comprising: an elongate plate body configured to extend along a length of a patient's stable metatarsal, the elongate plate body comprising an inner surface configured to engage the stable metatarsal and an outer surface, wherein the elongate plate body comprises a first end and a second end and a longitudinal axis extending between the first end and the second end, wherein the longitudinal axis is configured to be parallel or substantially parallel with the length of the stable metatarsal; two buttress wings extending from opposite sides of the plate body, each of the buttress wings comprising an inner surface configured to engage the stable metatarsal and an outer surface, wherein the inner surfaces of the buttress wings at least partially face each other so that when the plate body and the buttress wings are placed against the stable metatarsal, the stable metatarsal is at least partially surrounded by the elongate plate body and the two buttress wings; and a transverse opening located between the first and second ends (422, 424) of the plate body, wherein the transverse opening extends perpendicular to the longitudinal axis and is aligned with the two buttress wings such that when the plate body and the two buttress wings are placed against the stable metatarsal and cerclage material passes through the transverse opening and is tied around the stable metatarsal, and is then secured to the patient's unstable metatarsal, the cerclage material extends over the two buttress wings; characterized by raised ridges or flanges disposed along the buttress wings, or a groove disposed within the center of the wings, the raised ridges or flanges or groove being configured to maintain the position of the cerclage material centered over the wings after the cerclage material passes through the transverse opening. an elongate plate body configured to extend along a length of a patient's stable metatarsal, the elongate plate body comprising an inner surface configured to engage the stable metatarsal and an outer surface, wherein the elongate plate body comprises a first end and a second end and a longitudinal axis extending between the first end and the second end, wherein the longitudinal axis is configured to be parallel or substantially parallel with the length of the stable metatarsal; two buttress wings extending from opposite sides of the plate body, each of the buttress wings comprising an inner surface configured to engage the stable metatarsal and an outer surface, wherein the inner surfaces of the buttress wings at least partially face each other so that when the plate body and the buttress wings are placed against the stable metatarsal, the stable metatarsal is at least partially surrounded by the elongate plate body and the two buttress wings; and a transverse opening located between the first and second ends (422, 424) of the plate body, wherein the transverse opening extends perpendicular to the longitudinal axis and is aligned with the two buttress wings such that when the plate body and the two buttress wings are placed against the stable metatarsal and cerclage material passes through the transverse opening and is tied around the stable metatarsal, and is then secured to the patient's unstable metatarsal, the cerclage material extends over the two buttress wings; characterized by raised ridges or flanges disposed along the buttress wings, or a groove disposed within the center of the wings, the raised ridges or flanges or groove being configured to maintain the position of the cerclage material centered over the wings after the cerclage material passes through the transverse opening.
