Rickets. 213 



the angles of the ribs are as usual unduly prominent. The 

 lumbar spine is comparatively unaltered. The pelvis is 

 flattened from before backwards, and the lower end of the 

 sacrum and coccyx project into the outlet. 



Lower Limbs. — The bones of the right leg are longer and 

 better developed than those of the left. The femora on 

 both sides are curved forward near the upper end. 



The tibiae and fibula? are bent forwards and inwards, this 

 change being specially seen on the left side, where the shape 

 of the fibula reminds one of an Australian boomerang, and has 

 been firmly pressed against the tibia. There is a very marked 

 projection on the outer side of the os calcis on either side. 

 The bones of the upper limbs are not so much distorted as those 

 of the lower. They show a certain degree, especially in the 

 humeri, of the alteration noted in the previous skeleton, but 

 the changes are much less than in the lower limbs. The right 

 radius seems to have sustained a Colles' fracture.

6^ 28. Skeleton affected by Rickets. — Skeleton of an adult 



woman — macerated, showing rickety changes in the lower 

 limbs and pelvis. 



There is a very slight lateral dorsal curve, not sufficient to 

 have distinctly altered the thorax. The pelvis is somewhat 

 flattened from before backwards. In the lower limbs the femora 

 are curved forwards and outwards at the upper ends, and the 

 linea aspera in each case is remarkably prominent. The tibice 

 and fibulae are bent inwards about the middle, with the usual 

 ridges on the concavity. The bones of the feet show scarcely 

 any alteration, except for the prominence of the tubercle on 

 the outer side of the os calcis. B. C. i. 3. M. 22.

and costal cartilages from an adult — macerated, to show the 

 above.
