92 Injuries of Bone. 



above the lower end, is brought near the ulna. The articular 

 surface for the carpus looks slightly backwards, and the styloid 

 process has been displaced upwards. These alterations resemble 

 those found in Colles' fracture, which, however, is usually at a 

 lower level. The ulna at its lower end is bent away from the 

 radius, and its styloid process projects unduly. G. C. 278.5.

in Colles' Fracture. — Skeleton of a left hand and wrist, and 

 sections of a left radius, to illustrate the above. G. C. 3271.

3. 133. Recent Compound Colles' Fracture.— Right hand 

 and forearm of a young woman — in spirit, with the tendons 

 dissected at the back, to illustrate the above. 



The patient while drunk had been tripped up on the street. 

 Acute septic inflammation ensued, and was followed by spreading 

 gangrene, for which amputation through the upper arm became necessary. 

 For many days after the amputation her life was in danger, but she 

 ultimately made a good recovery. 



The wound made by the lower end of the ulna is shown 

 in front. The lower end of the radius has been comminuted 

 and the styloid process of the ulna broken off. G. C. 3271.

3. 134. Badly united Colles' Fracture.— Skeleton of the left 



forearm of an old person — cleaned and dried, showing the above. 



The radius has been fractured about half an inch above its 

 lower end ; the carpal articular surface has been forced back- 

 wards and upwards, and looks obliquely backwards. Its 

 styloid process is now on a level with that of the ulna. 



The carpus and lower fragment of the radius thus project
