6. 36. Distortion of the Pelvis from Rickets —Pelvis of a 



rickety person — macerated, to show the above. 



The pelvis is flattened from before backwards, especially on 

 the right side. This want of symmetry has probably been due to 

 lateral curvature. The sacrum is straight at the upper part, and 

 bends acutely forwards at the junction of its third and fourth 

 pieces. " Interesting as connected with the operations of 

 Midwifery." The bones are small, but ossification is complete,

6. 37. Distortion of the Lower Limb from Rickets.— Skeleton 



of the left leg of the same rickety person from whom the speci- 

 mens 6. 32 and 6. 33 were taken — macerated, to show the above. 

 The bones are stunted in growth, bent, and relatively 

 enlarged at the ankle and knee. The neck of the femur is 

 bent so that the great trochanter is higher than the head. The 

 shaft is curved, with the convexity of the bend directed forwards 

 and outwards, and flattened as usual from side to side. The 

 tibia and fibula towards their lower ends are markedly bent. 

 The curvature is also directed forwards, and has, besides lateral 

 flattening, a development of bone in the concavity of the arch. 

 Eelative to the lower end of the tibia, the foot is in the position 

 of extreme flexion. B. C. i. 3. M. 34. 



6. 38. Distortion of the Lower Limb from Rickets. — Skeleton 

 of the right lower limb, from the same patient as the preceding 

 — macerated, showing corresponding changes.

6. 39. Distortion of the Leg" from Rickets.— Plaster cast 



of a right leg, showing the above. 



The patient was a boy aged about 14 years.
