The D-shaped window on the back of a Mehta cast actively assists in the derotation of the child’s most prevalent curve with every breath the child takes. The D -shaped window should always be placed on the concavity side of curve, not past the midline. This special window allows the oblique ribs on the cavity side to grow out of the window, while the ribs on the convexity side are molded down to improve overall body shape and decrease rib hump.
