Fractures of the Badnts and Ulna. 91 



3. 129. United fracture of the Radius between the attach- 

 ments of the Pronator Radii Teres and Supinator 

 Brevis, — Plaster of Paris cast of a right radius showing the 

 above. 



The fracture has united in a bad position in two ways. 

 Besides a distinct angular deformity there has been a relative 

 rotation of the two fragments ; the upper is in supination, and 

 the lower in pronation. 



This latter deformity can only be prevented by treating 

 the fractured limb in the supine position. G. C. 3089.

3. 130. Fracture of the Radius, below the Pronator Radii 



Teres. — Right radius — macerated — showing the above. 



The fracture has been badly united. The ends overlap, 

 and the upper fragment has been drawn inwards, and has 

 evidently been united to the ulna, while the lower fragment is 

 somewhat pronated. W. C. G. 17. 



3. 131. Fracture of the Radius beween the Pronator Radii 

 Teres and the Pronator Quadratus. — Longitudinal section 

 through a right radius — macerated — showing the above. 



The fragments overlap, and the lower one has been drawn 

 inwards, and is pronated. The medullary canal where exposed 

 on the overlapping fragments has been closed in, but it has not 

 been re-established in the interior. F. P. C. 75.

3. 132. United Fracture of the Radius near its Lower 

 End. — Skeleton of a left forearm — cleaned and dried, showing 

 the above.
