214 Diseases of Bone. 



The bone is much increased in breadth (3 inches in manu- 

 brium) but is stunted in length, and the angle of Luo<livici 

 is much increased. The body is twisted to the right and the 

 manubrium to the left. B. C. i. 3. M. 29. 



6. 30. Distortion of the Stepnum from Rickets. — Sternum 



and parts of clavicles, costal cartilages, and anterior ends of true 



ribs, from a rickety person— partly macerated, to show the above. 



The sternum is bent backwards, forming a projection in 



front opposite the second and third costal cartilages, and measures 



3 inches at its greatest breadth, " while that of a very strong man 



6 feet 2 inches in height, measures \^ inches" (Sir Charles Bell). 



The costal ends of the ribs are increased in breadth, but 



there are no remains of the bead-like enlargement seen in rickety 



children. From the complete ossification of the sternum and 



calcification of the cartilages, this has evidently been an old 



. .person. W. C. G. 34 a. 



6.31. Distortion of the Humerus from Rickets. — Left 



humerus from the same skeleton as 6.34, 6.35, and 6.50 — 

 macerated, to show the above. 



The bone is stunted, and there is the same projection of 

 the deltoid attachment, flattening of the head, and enlargement 

 of the condyles which was noted in the description of the rickety 

 skeleton, 6. 25. B. C. i. 3. M. 30. 



6. 32. Distortion of the Upper Limb from Rickets.— Bones 



of the right arm and shoulder girdle — macerated, to show the 

 above. The terminal phalanges of the fingers are wanting. 

 (See also 6. 37.) 



Excepting the bones of the hand, the others are all more 

 or less stunted and distorted. The curves of the clavicle 

 are increased, and the scapula is bent forward below the
