The same relationof the shoulder-girdle is to be noticed in single curves to the left which are ac-companied by bony rotation, the position again being the reverse of that seen inleft total scoliosis. 6o DESCRIPTION AND SYMPTOMS The disappearance of concave-sided torsion which has once existed in anypart of the spine may indicate that the compensatory change has already begunand that the so-called total scoliosis has begun on its transition to a compoundcurve. We should, therefore, regard with suspicion any case of apparent total scoliosisthat shows any departure from the clinical type described (see page 55), such casesprobably having entered on the stage of Fig. 46.—Experimental Double Curve (Right Dorsal, Left Lumbar) Produced inTHE Model by Elevating the Right Side of the Pelvis and Having the ModelActively twist the Upper Spine, Face to the Left. That left total curves most frequently change to right dorsal, leftlumbar compound curves than to any other form is shown by thefigures of Hess and by a statement of Schulthess.^ But we cannotexpect the same final curve always to result from the same initialcurve. Various forms of curves may occur from the same simplecurve. For example, the dorsal region may not react as described, ^Liining and Schulthess: Orth. Chir., 1901, page 248. STRUCTURAL SCOLIOSIS 6l and the dorsal and lumbar region may }deld, as a whole, to the left,later showing bony rotation on the left side. The spine has yieldedbackward and to the left as a whole, and other types of compoundcurves may obviously result from the same initial curve. In his investigations concerni
