Lateral Curvature of the Spine. 511 



of the angles of the ribs on the concave side is masked by the 

 compression of the ribs together. The compression of the left 

 side of the chest, and opening out of the right side, must have 

 produced a corresponding depression of the left shoulder, and 

 elevation of the right one. B. C. i. 3. M. 14. 



7. 210. Advancing Lateral Curvature of the Spine.— Spinal 



column and pelvis of a woman — macerated, showing alternating 

 curves in the dorsal and lumbar regions. 



The first curve, beginning from above, is towards the right 

 side, and has its maximum about the fourth dorsal vertebra. The 

 second curve is towards the left side, and reaches its maximum 

 at the tenth dorsal vertebra. 



When viewed from behind, the curvature seems to begin 

 about the third dorsal vertebra, and extends from that part 

 downwards towards the left. B. C. i. 3. M. 5.

7. 211. Advancing" Lateral Curvature.— Cervical, dorsal, and 



upper lumbar portion of a spine, with the ribs attached — 

 macerated, illustrating the above. 



There is a curve to the left in the cervical and upper 

 dorsal region, having its maximum at the third dorsal vertebra. 

 There is also a very slight curve to the right in the lower dorsal 

 vertebrse, reaching its maximum about the ninth vertebra. 

 There is a slight rotation of the vertebrae towards the con- 

 vexity of the upper curve, and, in consequence, the upper ribs 

 on the left side are raised and separated, and have their angles 

 projected backwards, while the corresponding ribs on the 

 opposite side have their angles flattened, and their shafts 

 thrown together and depressed. In the lower ribs the angles 

 are somewhat increased on the right side, and flattened on the 

 left, corresponding to the alternating convexity of the curve.
