Additional dorsal or plantar displacement of the distal osteotomy fragment. When distal osteotomy fragment is displaced laterally by magnitude T, we get two approximately cylindrical fragments of diameter W with the distance between the edges of these cylinders being exactly T. If the distal osteotomy fragment is additionally displaced in the dorsal or plantar direction by the magnitude of x (i.e., in the lateral radiographic projection), the bony fragment overlap in the AP radiographic view remains apparently equal while the true displacement between the two cylinder edges is increased
