FKACTUKES OF THE KADIUS AND ULNA. 



3. 127. Badly United Fracture of the Radius and Ulna. 



— Left radius and ulna of a young person — macerated — show- 

 ing the above. 



The bones have been united at a considerable angle, and 

 there is callous thickening round the seat of fracture, especially 

 on the radius. 



The epiphyseal lines are apparent at the lower end of both 

 bones on the dorsal aspect. 



This has probably been a fracture of the radius and a green- 

 stick fracture of the ulna. F. P. C. 74. 

 Presented hy Professor John Thomson. 



3. 128. Fracture of the Bones of the forearm, Radius 



ununited. — Bones of the right forearm of an adult macerated. 



The ulna, fractured a little below the middle, is united in 

 bad position. The lower fragment is displaced inwards from 

 the upper, and is somewhat rotated inwards on its own axis. 

 The head and styloid processes are greatly altered, apparently 

 by arthritis deformans. 



The radius has an ununited fracture about the middle. 

 The broken ends are enlarged and irregular, and their contiguous 

 surfaces are rough. At the lower end the radius has been 

 broken about half an inch above the articular surface, and the 

 lower fragment has been displaced outwards and backwards, but 

 without much rotation backwards. The styloid process has, 

 however, thus been raised above the level of that of the ulna. 

 This injury might be called a form of Colles' fracture.
