A treatise on orthopedic surgery . Congenital total scoliosis. The rotation is much greater than the lateral devi-ation. Compare with Fig. 91. LATERAL CUBFATUBE OF TEE SPINE. 153 distortion is most noticeable (Fig. 91), but when the body isbent forward tbe twist of the trunk becomes the prominent de-formity (Fig. 92). If the thoracic region is involved, the ribson the side toward which the spine is rotated project backward, Fig. Primary lumbar curvature to the left. A flat back marked rotation with butslight lateral curvature. and on the other side of the spine there is a corresponding flat-ness or depression. The projection of the ribs due to the dis-tortion of the thorax is far more noticeable Ihan is the simpletwisting of the free portions of the spine in the neck or loins;and in these regions the projecting transverse processes coveredby the thick layers of muscles, yet unaccompanied by markedlateral deviation, may cause mistakes in diagnosis. In the 154 OBTHOPEDIC SUEGEBY. cervical region, for example, as an accompaniment of acute tor-ticollis, the projection may be mistaken for abscess; and in thelumbar region it has been mistaken for a new-growth attachedto the spine. Although persistent lateral curvature of the spine is alwaysaccompanied by rotation, the degree of rotation does not alwayscorrespond to that of the more evident lateral deviation. In the Fig. 94.
