Cast wedging using vector and geometrical analysis demonstrated that the open wedge produces distraction of the fracture, the closing wedge shortening, and that the opening--closing wedge can perfectly correct skeletal deformity. The level of wedging should lie at the axis intersection, i.e., at the intersection of the long axes of the 2 major fracture fragments. An open wedge at the axis intersection is recommended for tibial shaft fractures immobilized with long leg casts; an opening--closing wedge at the axis intersection, for fractures immobilized with "pins and plaster".
