Simulated osteotomy procedure for the first metatarsal. a: AP view of osteotomy and movement of the bone segments. The osteotomy was perpendicular to the longitudinal axis of the second metatarsal, while the movement direction was parallel to the axis. b: A lateral view of osteotomy and movement. The osteotomy was perpendicular to the reference plane, while the movement direction was parallel to the plane. c: Lateral views of metatarsal bones shortened by different length in FE mode
