Abstract: A system and method for a ROSE-Reverdin osteotomy obviates severe deformities having a high intermetatarsal angle and which require closure via osteotomy (bone cut) of the first and/or fifth metatarsal in the midshaft or proximal aspect of the bone. The ROSE osteotomy is utilized to achieve this correction and is performed without need for fusion of the first metatarsal cuneiform joint. The ROSE osteotomy achieves correction of the intermetatarsal angle via rotation of the first and/or fifth metatarsal about a proximal based axis point. The Reverdin osteotomy is required to correct a deviated articular cartilage deformity at the head of the first metatarsal and/or additional slight correction of the IM angle. The Reverdin osteotomy achieves correction by wedging of the cut to realign the cartilage and translation of the head of the first metatarsal for further IM correction. A unique jig is used to achieve this cut and fixation.
