Lateral Curvature of the Spine. 513 



is to the left, and its maximum about the eighth dorsal vertebra. 

 There are also compensating curves to the right in the upper 

 dorsal and lumbar regions respectively. The rotation of the 

 bodies of the vertebrae towards the convexity is well shown, and 

 in the main curve to the left the corresponding changes in the 

 ribs are also well marked. Thus there is a projection of the angles 

 backwards at the convexities, i.e. below on the left and above on 

 the right ; and a flattening of the angles at the concave portions, 

 i.e. below on the right and above on the left. It should 

 be noted, however, that the ribs at the convexity or left side 

 below are not separated, but are rather thrown together. This 

 may be due to the effect of the pressure of the ribs from above.

 frequent form of lateral curvature combined with stoop, caused 

 by standing or sitting in a bent position." B. C. 1. 3, M. 8.

column, from third cervical vertebra downwards, with pelvis

There is a series of alternating lateral curves, i.e. to the 

 left in the upper dorsal and in the lumbar region, and to the 

 right in the mid-dorsal and in the cervical region. The spine, 

 as a whole, is bent forwards, and the normal curves are as usual 

 diminishetl. The usual rotation of the bodies towards the con- 

 vexity is best seen in the strong curve to the right in the mid- 

 dorsal region. A development of bone at the inter-vertebral 

 borders from arthritis deformans is well seen on the left side of 

 the eighth, ninth, tenth, eleventh, and twelfth dorsal, and 

 first lumbar < itebrae ; and on the right side of the second and 

 third lumbiir n ertebrae. Figured by Shaw "on Distortion of the 

 Spine," as a " pipentine Curve," plate 1, fig. 2. W. C. G. 14.
