DEFOEMITIES OF THE LIMBS. 



Up'per Limb. 

 a. From Deficiency in Development. 



11. 9. Deficient Development of the Hand.— Plaster of Paris 



cast of the arm of a child, illustrating the above. 



The hand is wanting, and only a few rudimentary stumps 

 indicate fingers. G. C. 2548. 



Presented by Dr Braidwood. 



11. 10. Congenital Absence of the Radius.— Plaster of Paris 



cast of the left hand and forearm of a young person, showing 

 distortion, consequent on the above. 



The forearm is bent towards the radial side, and the ulna 

 projects at the wrist. The forearm is clumsy and short. The 

 thumb is poorly developed, and has apparently been devoid of 

 much power of movement, but the four fingers are long and 

 well developed. G. C. 3291. 



Presented h]j John Thomson, M.D., 1890. 



11. 11. Deficiency of Radius (?). — Plaster cast of the right hand 

 of an infant, said to be four months old, apparently illustrating 

 the above. 



The hand is bent in upon the radial side, so that the fore- 

 finger touches the side of the forearm. The thumb is absent. 

 The hand was said to have become straight, some years after 

 the cast was taken. G. C. 2547. 



Presented by Dr Braidwood, 1880. 



11. 12. Deficiency of the Radius (?). — Plaster of Paris cast of the 

 left hand from the same infant as the last, showing a similar 

 deformity.
