This rotation element is the result of the change in shape of the vertebrae which have yielded to the unequal superincumbent weight and have changed in shape, turning always, as they must, toward the convexity of the lateral curve. The curved region is stiff in motions, and the mobility is greater to one side than the other. Distortions of body outline, prominence of one hip, elevation of one shoulder, and a lack of symmetry in various directions are the expression of the spinal distortion. The curves are called right or left, according to the direction of their convexity, and are named cervical, dor Fig. 377.--Severe Case Of Spastic Paralysis.

If they embrace two regions, they are called cervicodorsal or dorsolumbar. Schulthess' table gives an idea of the relative frequency of the different curves in Germany, the material analyzed being patients received for treatment. This confirms common clinical experience that left curves are more frequent in the lower spine and right curves in the dorsal region. The commonest compound form is the right dorsal left lumbar type; in such a case the right shoulder is raised, the body displaced to the right, and the right arm hangs further from the side than the left. The right side of the chest is prominent backward and the left side of the lumbar region. The dorsal and lumbar concavities may be increased or the back may be abnormally flat. In a left lumbar curve the trunk is displaced to the left, the right ilium is uncovered and unduly prominent, and the left side of the body flatter than normal at the waist. The back...
