Scarf osteotomy. A, Placement of Kirschner wires at corner point of planned osteotomy. Standard orientation for lateral translation is 90 degrees to longitudinal axis of second metatarsal (A) and in approximately 20 degrees horizontal inclination to plantar surface (XY). B, Osteotomy cuts. C, Lateral displacement is obtained if short osteotomy cuts are perpendicular to longitudinal axis of foot. D, Proximally oriented inclination of short osteotomy cuts caused shortening depending on angle of inclination and amount of translation. E, After lateral displacement, osteotomy is fixed with two minifragment screws.
