JThe rotation appearances are marked, and the sharp anglesof the upper ribs are prominent in the lower part of the curve, whileabove the rotation is less evident because there are only the transverseprocesses of the cervical vertebrae to make a projection. The trunk isdisplaced to the side of the convexity of the lateral Fig. 47.—Left Dorsolumbar Scoliosis, COMPOUND STRUCTURAL CURVES. 6l COMPOUND STRUCTURAL CURVES. The pictures of compound curves cannot, of course, be as simple or uniform as those of the simple types. A right dorsal left lumbar curve, for example, will present a combination of the appearances described in both dorsal and lumbar curves, a right cervicodorsal left dorsolumbar the sum of thepictures of the two factors. If thedorsal element predominates, theappearances will be more dorsalthan lumbar, as is usually the case,and every grade of variation is to
