Rickets. 217 



The bones have been altered in a way quite similar to 

 that seen in the preceding specimen. The bend has been 

 about the same spot, and the altered shape of the bones is 

 traceable through the covering of the soft parts. The foot was 

 quite flat. The cast was taken when the sole was resting on 

 the ground, to show this point. G. C. 3284.

6. 40. Distortion of the Femur from Rickets. — Right femur 

 of an adult — macerated, to show the above. 



The bone is stunted. The shaft is curved forward a little 

 above the middle, and shows the usual lateral flattening 

 at the curve, with increase of bone in the concavity. The inner 

 condyle is unduly prominent downwards, and the person has 

 probably therefore been knock-kneed. G. C. 1001, 



6.41. Distortion of the Femur from Rickets. — Section of 

 the right femvir of an old man — macerated, to show the above. 

 The bone is short and curved greatly forwards. The neck 

 has sunk so as to relatively raise the trochanter. The section 

 shows that at the bend the compact tissue is increased in front 

 and even more so behind, and that the medullary cavity there is 

 occupied by cancellous tissue. The femora were the only bones 

 distorted in this case. G. C. 3085.

6. 42. Distortion of the Femur from Rickets.— Right femur 



of an adult — ^macerated, to show the above. 



The bone is stunted and the shaft curved forwards about the 

 middle, with a corresponding lateral flattening of the curve and 

 development of bone at its concavity. The angle of the neck is 

 obtuse, and the trochanter is raised relatively to the head. 

 The inner condyle projects downwards, so that this also has 

 probably been a case of knock-knee. B. C. i. 3. M. 37.
