Fractures of the Hadms and Viva. 95 



liackwards. In consequence the radius was broken. The fracture was 

 at first enclosed in splints, without being reduced, and the patient was 

 sent by the surgeon of the works to a surgeon in Edinburgh. The latter, 

 on the supposition that the fracture had been set, left it in the splints, 

 and lastly, the patient, by some mistake, did not return for six weeks to 

 have the splints removed. In consequence the hand became practically 

 useless. Refracture was found impossible, and massage did no good. 



It will be observed that there is little or no lateral 

 displacement. This confirms the view that the usual presence 

 of lateral displacement is due to the direction of the breaking 

 strain. G. C. 3100.

3. 141. United Fracture of the Ulna.— Lower part of a right 



ulna, macerated, showing a fracture united with some displace- 

 ment and considerable callous. 



From the diminution of the articular surface the range of 

 pronation and supination must have been greatly diminished.

3. 142. United "Smith's" Fracture.— Right radius and ulna, 

 carpus, and part of metacarpus — macerated, showing the above. 

 There has been a fracture through the lower end of the 

 radius, just above the articular surface, with a displacement 

 similar to that seen in Colles' fracture, only forwards instead of 

 backwards. The styloid process of the radius is at a higher 

 level than that of the ulna. The articular surface of the radius 

 looks now very obliquely forwards. The normal hollow, just 

 above the articular surface in front, is increased, while there is 

 a marked projection at a corresponding place at the back. There 

 are deep grooves on the back of the radius for the tendons of 

 the extensor secundi internodii pollicis and the extensor indicis. 

 This fracture is produced by a forcible bending of the hand 

 forwards, i.e. in a direction the reverse of that in which Colles' 

 fracture is produced. Gr. C. 3551.
